Physop plan and engineering setup for Monday 6/22/2009

If the TF scanner is available we will complete power testing with
TF tests and proceed to attempt to get plasma.

If not, we will start the first part of
MP#555 PF Error Field Evaluation and Compensation,
which calls for long single supply PF pulses under DPCS control.
Note that depending on results, it may be necessary to modify the
EF3 and EF4 bus connections to pulse the upper and lower coils independently,
as was done on 1030717. It would also be necessary to change the A-coil
taps; see detailed physop run plan below.

Physop plan for plasma operation:
----------------------------------
Prior to first attempt, complete implementation of modifications
to account for deceased flux loops f23 and f25:
1) Install new ian_007 tree in /usr/local/cmod/codes/pcs/ian/ and new
version of ianup.pro in /usr/local/cmod/codes/pcs/user_algs/contihh/
2) Turn off input_18 and input_20 (f23 and f25) in top.config.inputs
and input_018 and input_020 in top.dpcs_config.inputs. Also,
update the contents of four BP loop inputs that Bob will have
changed: inputs #41,43,47,54 which correspond to BP12,14,18,25.
3) Change analysis::recon_vac:static_shot from 2003 to 2015
4) Modify the coefficients in analysis::top:fluxihh using
/usr/local/cmod/codes/mhd/fluxihh/load_predictors_procedure.sh
5) change the weights of efit_efitin:fwtsi[[22:24]] to 0. in the
analysis_model and efit_model trees.
6) Insert a bogus synthetic expression in magnetics::mag_fluxes:flux_22
and flux_24 so that MFLUX and the vacbrbz routines won't choke (and
may even give decent approximations).
7) If possible, arrange for Ian to copy the new versions of ianup.pro
and ian_007.* to his directories, so that mflux and mfil might work.

Start with Seg 1 and 2 from 1080523011, as successful ohmic 750ka, 7e19
shot from the last day of operation. Recalculate all magnetics predictors
in all segments (or just 1 and 2 and zero out 3 and 4).

Tweak fields and gas as well as I can, and hope for something other than
duds to tune to. Last time (1071127-29) we went for long stretches with no
plasma, but at least we had fizzles. We also had more loop failures, all fixed
by zapping.

Physop summary for Monday, 6/22/2009

This was a difficult day, but some progress was made. We took Option#1,
aiming for a plasma shot after completion of TF testing. We completed
the TF tests, but found another problem that prevented a successful 
plasma on the one attempt we made. We plan to continue this line tomorrow,
after a hardware repair (see below).

The day began with a series of test (no-power) shots to test 
the TF scanner. Eventually the bugs were worked out and the scanner
software became functional. It was then discovered that some of the 
taps were plugged into the wrong place, resulting in bad values from
the scan. This was remedied by swapping plugs, and the TF turn resistances
were determined to be quite good. 

Once the scanner was working properly, we had to wait for the alternator
to get up to speed; they had some difficulty which delayed the spin up
this morning. Shots#8-14 were TF tests under PLC control. After the first
one of these, we discovered that the polarity of the new \BTOR signal
is reversed, so Bob had to change the expression in the tree. This required
that I recalculate all the magnetics predictors (at least the ones that
include the bp_coils, which need BTOR pickup correction) again before we 
tried out first plasma attempt on shot#15. During the course of the tf tests,
the engineers also discovered a bad camac channel reading the tf supply 
voltage, and moved this signal to a different input.

Shot#15 was a full plasma attempt based on the prepared model 1090622000,
with the magnetics predictors re-recalculated to account for the 
change in btor sign. The result was a dud due to excessive BR_0 (over 70mT),
with the BR_0 feedback driving the OH2's in opposite directions, taking OH2U
to its current rail. At first I thought that the predictor was somehow screwed
up, since the sign of the feedback error was backward from the actual
Br0 value, as indicated both by vacbrbz and recon_vac signals. After an 
hour and a half of head scratching and software tests, I decided there might
be something wrong with the dpcs input signals. To investigate this further
we took a PLC controlled test shot (#16 a 10Ka oh commutation, like 1090619025,
but without the EF4), so I could see a case with more or less balanced 
Br_0. Again the feedback signal on BR_0 was large and not consistent. Finally
I found that the dpcs input_009 signal  (F10) was about half the amplitude
it should have been based on the F10 signal from the magnetics. It turns
out that the iso-amp channel appears to be bad, probably the gain of 2 output
amplifier. Shot #17 was a repeat on which I verified that the problem 
was not in the dpcs digitizer by teeing off the input_001:016 to the
high channels of diag_hw:dt196_1. We then tried (#18) to workaround this problem
by swapping the F10 signal over to dpcs input_028, which was previously labeled f28 (no longer exists) but had actually been connected to a diamagnetic
comp loop, which had also been removed from the machine last year. 
I changed the hybrid config inputs to reflect this change, but missed some
nodes that also needed to be changed, so when I tried to recalculate
the BR_0 predictor to use this it still didn't work correctly, although
the signal on input_028 looked correct. 

After the run we determined that Willy Burke could probably repair the 
bad iso-amp board in the morning, so I have restored the hybrid config in the 
tree to its former state (F10 on input_09 turned ON, and f28 on input_28
turned OFF, with appropriate values in the QUANTITY and STRUCTURE sub-nodes.
Bob still needs to reconnect the cables to correspond to this. He should
just leave input_28 with no input. The iso-amp chassis has had its 
fans unplugged and DC power cable removed, and the cover loosened, in 
preparation for the repair. The correct circuit card has been identified,
we think. I have also reloaded the PCS model from shot#15, which should 
work once the repairs have been made. I recommend another PLC controlled 
test shot to confirm the feedback signal, followed by plasma attempts.

Bring up PCS (the real one) 
Get the config warning, as expected.
The model file is the power test case from Friday.
Start to update the predictors, but I must have clicked something funny
It's not doing the apply on wire 3. Something about linking the waveforms? 
Worked that time, maybe I hit apply before it finished the call.
Continue. 
OK, do the load.
Load at 22-Jun-2009 07:15:20.00

Ready for shot#1, which should be a no-power test of the scanner
(and everything else)

Jun 22 2009 08:14:54:463AMSteve Wolfe
Finally getting around to looking at the PCS for 1030717007
which is the model for the first shot of the MP#555 experiment.
Of course, tere is no dpcs tree for this one, which is ok.
It uses only seg1, which is also fine. I'm looking at it in a pcs,/safe
in a separate scratch directory. Probably the best thing to do is to 
zero out the wires 4-6 which have plasma predictors on them, and then
do imports and cut&paste for the waveforms on the different shots.

Zero wires 4-6, 16. 
Build segment in segment 1.
Zero segs 2-4
Build All
save as 1090622999 in alcdata-test::/cmod/trees/test/pcs and dpcs/

 Getting some scanner data now.
However, it looks bad. Progress though, at least there is
something there now.

Jun 22 2009 09:08:07:187AM1090622006Steve Wolfe
Shot#6: Another no power cycle to test scanner
  getting scanner data, still looks like groups of 
high readings. 
It looks like these may be the same values getting stored over again.

Jun 22 2009 09:35:08:710AM1090622007Steve Wolfe
Shot#7: Another no power cycle to test scanner
 After a cell access to swap some plugs. There seems to
be some doubt as to whether the previous data are duplicated or not.
This time the data look good (or at least better).

Jun 22 2009 09:38:44:463AM1090622007Steve Wolfe
We may be ready on the scanner. 
Now waiting for the alternator to come up to speed;
they got off to a slow start this morning. 

Jun 22 2009 10:29:51:233AM1090622008Steve Wolfe
Shot#8: 25kA TF test PLC control
Ratiomatic is now connected, so we'll do gas
on B-top and B-main. Programming is like last Friday.
Got TF current, but the bus_lv signal is oscillating 200A
Bob is measuring +0.8Tesla; the new loop may have the wrong
polarity! Easy to fix in the tree for \Btor, but will dpcs
work? The sign at the input dpcs is indeed positive, and
it used to be negative. 

Bob needs to change the definition of \Btor in the magnetics tree.

Jun 22 2009 10:45:57:570AM1090622008Steve Wolfe
After shot#8, Bob changed the definition of \BTOR in the tree
to account for the new minus sign. I need to recalculate all 
the mag predictors again to pick this up. I've verified that
the get_p2v routine picks up the new value.

Also, F22 is now reading zero,  Bob is going to go zap it. 


Jun 22 2009 11:09:51:390AM1090622009Steve Wolfe
Re-Call wires 1-4 in seg1 (only ones using bp-coils)
to pick up the changed sign on btor.

Irby found a disconnected cable to his cPCI digitizer,
should work next time. 
Bob zapped f22, it was nearly open, now back to normal.

Shot#9: 50kA TF test PLC control
Got tf rog signal. btor signal looks normal, now. 
I'm not getting demand on pg3; that's because the fizzle is
at 0.08sec and the programmed pulse starts at 0.38.
Btop is working
F22 is fixed but now f14 is dead. Bob back in to zap that.

Jun 22 2009 11:40:32:760AM1090622010Steve Wolfe
Shot#11: Stretch the pg3 pulse out and raise to 100V
Shorten pg4 down to 20msec as on normal shot

Shorten pg4 down to 20msec as on normal shot 
Another 100kA TF test
Ran ok, but the engineers are worried about something
Got some gas maybe from B-main. Next shot I'll turn btop off
to be sure. 

Jun 22 2009 12:34:37:063PM1090622012Steve Wolfe

150kA TF pulse under PLC control. 

Problem in INIT, do a no-power (but should get gas)
Got gas starting at -.4sec or so, rising to over 1mTorr.
PG3 is working now. Next shot make it narrower pulse

Jun 22 2009 01:28:51:257PM1090622013Steve Wolfe
Shot#14: Next shot will be the plasma attempt. 
I need to recalculate all the predictors because of the
BTOR sign change. 
First, blow away the scond PCS and do it in the live one

I really need to be careful with these, because I can't tell
if I miss one by anything that displays in PCS.
Load from 1090622000
recalc all four segments. 
Build all - no warnings
Change title of seg2 to "2009 0.75MA, SNL"

Actually, Bill wants to do another PLC TF test,
so they're going to disable the other supplies. 
This will be 165kA PLC control
Got 160kA or so, 
Compare the \top.LOADABLES.BIT_A:MATRICES from 1090622000
and 1090622014 to verify the change of signs in btor.
There are 34 differences and they all look like the signs.
I think it worked. All the differences are for input_57, which is BTOR.


Jun 22 2009 01:32:06:833PM1090622015Steve Wolfe
Shot#15: Next shot will be the plasma attempt. 
Still no halpha or CIII, but Zmeter is being digitized. 
No current, no light - DUD. 

Horible BR_0, over 70mT!
OH2's are very imbalanced, some problem in BR_0




Jun 22 2009 03:08:15:917PM1090622015Steve Wolfe
Shot#15: Something is screwed up in the feedback. It almost
looks like the sign of Br_0 is backward? 
Yes, this predictor is backward somehow. 
The sign was correct on my test shot 1090621201, at least
it matched the signals from 1080523011 
Run another test shot 1090622201, using data from 1090622015. It does what it
did, and it looks like the sign is backward. 
Now try another test 202 using 1090621201 as the model; this should
get the predictor I tested yesterday. Accidentally made 1090522202 instead
of 1090622202, but it did the same thing. Somehow, it now thinks the 
br is negative when it's really positive. 

All of the signs look correct, down to the contents of the dpcs loadable
\HYBRID::TOP.DPCS.LOADABLES.BIT_A:MATRICES which have the reverse
sign of the predictor, which has the reverse sign of the physics predictor
because the p_to_v is negative. It all checks out. 

I'm going to re-run the commutation test from Friday 1090619025
to see if there is something funny in the signals, and see what the
br_0 signal does without feedbck



Jun 22 2009 03:24:13:003PM1090622015Steve Wolfe
Shot#15: It isn't just a sign problem. The phys_aout also has
different magnitude. It looks like there may be a problem
with the inputs. The phys_aout is seeing about -.02T, while the
BR_0 in recon_vac is around +.07T



Jun 22 2009 04:07:29:630PM1090622016Steve Wolfe
Shot#16: 10KA OH comm test with PLC control
And we got some ef3 induced. 
And the phys_aout signal for Br_0 is completely weird.
For that matter, so is the Br_0.from recon_vac.
Recon_vac is giving near 0, maybe -.001. 
vacbrbz is giving -.005, but that must be because of
the bogus flux loop signals in \mag_fluxes.

However, the br_0 feedback signal is .015 (phys_aout is positive
which means the predictor of br_0 is negative).

I still believe that the predictor is the same as being 
used by recon_vac, so this means there may be a problem 
with the inputs. F10 input to dpcs is ~.2V, but the flux_full signal
is .3Wb, which should give .6V ! This could be the digitizer or more 
likely the iso-amp! 


Jun 22 2009 04:30:12:933PM1090622017Steve Wolfe
Shot#17: Repeat 10KA OH comm test with PLC control
Connect a ribbon cable from input1-16 to the second output
patch panel, going to inputs 49-64 on diag_hw:dt196_1

The signal on input_57 of diag_hw:dt196_1 agrees with input_009
with a signal level of about 0.2V, which is wrong. 
This means that the output of the iso-amp must be bad. 

Next shot Bob will move the f10 input from input_009 to input_028,
which is no longer used for the non-existent loop f28; it has something
else on it. If this works, we can change the hybrid config inputs
to use this input as f10. Would require recalculation, again, 
but it should work. Of course, if we move it back we need to
recalculate again. Depends on how long it takes to get the iso-amp
fixed. Also, need to consider calibration of the iso=amps; those
numbers are in p_to_v_expr:gain for each input, so it should be ok.

Jun 22 2009 04:52:30:037PM1090622018Steve Wolfe
Shot#18: Bob is swapping the F10 signal to input_028.
I will turn off input_009 and turn on input_028, change
the name of input_028 to "F10" and the one on input_009 to 
F10BAD, and recalculate the BR_0 predictor. If it works, 
can do the rest of them

Load it, gives a warning on the off diag test? It seems to think
f10 is turned off, but it isn't. Forgot to toggle the dpcs_config inputs
Do that and reload. Now it complains on all the others that used f10
before, but it's about f10bad. OK for a test
Load at 22-Jun-2009 16:40:05.00
Open tree /home/wolfe/pcs_scratch      -1

This should actually work as far as BR_0 is concerned. 
Turns out input_028 was some tf diamagnetic compensation
loop, and Bob swapped that onto input_09, but it won't hurt
since it's off. 

Signal is coming through ok on input_028, looks like the 
right magnitude, but br_0 signal in phys_aout is still 
garbage. Gives .04T error. Maybe it didn't actually load it
the new predictor. 

Jun 22 2009 05:03:16:087PM1090622018Steve Wolfe
Shot#19: Try calculating all the predictors and reloading.
However, I get an error in filament on the call:
% FILAMENT: Error -- can't match pflx names
% Array subscript for CMAT must have same size as source expression.
Open tree /home/wolfe/pcs_scratch      -1
Open tree done

And then it pops up a complaint that the predictor has all zero weights.
It must be due to the name. I'll try changing the name and structure
to what it really is, which is DCL2_HJ, a diamagnetic compensation
loop that has now been cut out of the machine. 
 Probably the filament routine is getting into trouble trying to 
find out the parameters for f10bad in the magnetics tree.
It's funny that it filled in values before it decided to crash.

Never mind, can't get it fixed before 17:00, so don't bother to take 
shot 19. Will work on this to get ready for tomorrow. 

Jun 22 2009 06:02:44:640PM1090622018Steve Wolfe
Back to the hybrid::top.config.inputs

For input_09 change name to "DCL2_HJ",
Quantity to "DIAMAG" and STRUCTURE to "MAG_DIAM" 
Doesn't matter since it won't find a get_p_to_v routine for this
structure, and doesn't need to.

For input_028 change QUANTITY from "FLUX_PARTIAL" to "FLUX_FULL"
and STRUCTURE from "MAG_FLUX_PARTIAL" to "MAG_FLUX_FULL"


However, Willy has schematics for the iso-amps, and we've
looked into the chassis and decided that this ought to be
fixable. He has also found the isolation board test circuit.
Therefore,  it has been decided to try to repair the iso-amp in the
morning and put things back the way they were.

I'm going to undo the changes I just made to
the tree. If I do that, we should be able to reload the tree from 
shot 1090622015 and proceed from there, once Bob has reconnected
the cables to input_09 and input_28 (don't really need to put 28 
back, since it's not connected to anything.)

Jun 22 2009 06:22:06:807PM1090622018Steve Wolfe
Back to the hybrid::top.config.inputs
again. 
Note that if I really want to re-use the tree from shot 15
without recalculating, I need to put the input_28 stuff back 
the way it was, not just blank it or call it dcl2_hj.

\top.config.inputs:Input_09: name from DCL2_HJ to "F10"
 QUANTITY from "DIAMAG" to "FLUX_FULL"
 STRUCTURE from "MAG_DIAM" to "MAG_FLUX_FULL"
Turn it ON

\top.config.inputs:input_28: name from F10 to "F28"
  QUANTITY from "FLUX_FULL" to "FLUX_PARTIAL"
  STRUCTURE from "MAG_FLUX_FULL" to "MAG_FLUX_PARTIAL"
Turn it OFF

\top.dpcs_config.inputs:input_009: turn it ON
\top.dpcs_config.inputs:input_028: turn it OFF

Now load from 1090622015
Do a build_all to see if anything squawks (it shouldn't)
EditWire Br_0 and examine the inputs/weights; all ok.
Do a call just to check. No complaints. ok it 
Now do the same for zcur2, be sure it doesn't complain; it doesn't.
Load this into the live model
Load at 22-Jun-2009 18:19:45.00
Open tree /home/wolfe/pcs_scratch      -1
Open tree done

OK, we're back where we were as far as the tree is concerned. 
If Willy can fix the iso-amp and Bob swaps back the cables to 
input_09 this should work. Recommend doing another OH comm test
just to check before we turn on feedback.
