PhysOp Plan

Load dpcs from a suitable shot such as 1090708027, 0.9MA, LSN
Proceed with cleanup discharges, monitoring RGA (if available) and HtoD

Things to try:
1) Reduce program density (not too far) to see how much wall fueling
we're doing. If I get locked modes, try turning off the A-coil and
see if the intrinsic threshold is higher or lower (count a few shots
toward MP#555).
2) Run upper null and/or inner wall limiter discharges to aid cleaning
of those surfaces.
3) Increase current back to 1MA and see if the cleanup/hydrocarbon generation
rate is still non-linear in the current. 
4) If I get really bored, try running pure helium discharges (including 
pre-puff). Call it development for the helium H-mode experiments (MP's to
be written). 

Expect to allow cell access for diagnostic shakedown, as requested.

Physop Summary for Thursday July 9, 2009
MP#298a: C-Mod startup and conditioning
SL?
PO: wolfe
EO: Parkin, Byford, Dekow

The run went relatively smoothly except for a SNAFU with the 
dpcs init action software (see below). We spent most of the day
running vanilla LSN 900kA discharges. Brian and Dan used these to do some
cleaning up of the scanning probes, but they were plagued by triggering
problems on their cpci digitizers, so only a few WASP and FSP scans
were done. The same problem prevented the heat profile data from
being collected, except for a few shots. I decreased the target
density down to 6e19, and more or less succeeded in getting down to 
this level without turning off the feedback. Didn't try to go lower.

After Brian finished/gave up, on shot#24-28 I changed to USN (using
seg3). These ran pretty well, and didn't show any major change in 
H or hydrocarbon evolution, although the mass 28 increase was larger
than in the LSN discharges. Again, got down to a target of nl04=6e19.
No sign of a locked mode in either upper or lower null. I didn't try
turning off the a-coil, leave MP555 for another day. 

Shot#29 I went back to seg2 and programmed for inner wall limited,
but only got marginally limited, bouncing around lower null still. 
The camera view and the EFIT reconstructions seemed to be consistent,
with light on the inner wall near the midplane and in the lower 
divertor. 

For shot#30 I programmed for more strongly limited (clearin
from -.015 to -.02) and, at Earl's urging, increased Ip to 1MA. 
This one ran well-limited, with loop voltage around 1.8V, and 
ended up railing OH1 near 1.3sec, and disrupted at 1.44sec with
just over 800kA. The disruption raised the hydrocarbon peaks by
about an order of magnitude, but wasn't nearly as dramatic as 
1MA disruptions of last week. 

The H/D levels in the plasma rose through the day (although there 
wasn't enough light to register in the USN shots until rampdown). 
The limiter case got up to H/D~0.5. M3/M4 on the RGA also rose 
through the day, indicating we were doing some good in liberating
H to be pumped away.

Startup was quite reliable today, and almost all the plasmas 
lasted full length until the disruption on shot#30. I fiddled
with the startup continuously, mostly to try to deal with runaways,
pretty successfully. There was one strange super-fizzle on shot#7, 
on which the zcur position ran rapidly up. This seemed to be due 
to a change in BR0, rather than Zcur feedback error. There seemed to
be no magnetics errors or power supply problems. I adjusted 
BR_0 by 0.5mT and made a gas tweak and the next shot was fine. There
was another fizzle later in the day (#22) that may have been similar,
but didn't get as far; I again tweaked BR_0 more negative and adjusted
the gas and got plasma back. BR_0 ended the day at .0005, which may
be too negative, but worked. 

The following long description is of interest only to 
DPCS and software people (me and Tom&Josh). 
The short story is that a problem occurred and has 
been patched. You may now skip to the end.
*********************************************************
BEGIN LONG, BORING ACCOUNT OF DPCS SOFTWARE ISSUE
*********************************************************
On shot#4 the cycle hung up because pcdaqdpcs3 rebooted between 
INIT and CHECK. We took a no-power shot, which did not record 
data and did not advance the shot number. Tom and Josh concluded 
that a network glitch had caused the reboot. This has happened before,
at least once. However, this time there was more than the usual fallout.

On the next shot cycle, also numbered #4, we got a report of 
a critical init action failure on the dpcs_init action. In fact, 
as shown by the logfile, the dpcs_init action had completed normally,
but the server received a report of an error status (!err=-5, 
which translates to
 MDSVALUE: %TREE-E-TreeNODATA, No data available for this node)
This symptom has been seen before in test scripts run on 
pcdaqdpcs4 since a reboot in May or June, but had not previously been
 reported as an action failure by the mdsip server to the dispatcher. 
Some software that got updated on the reboot must have changed this 
behavior. 

After the second time this happened, following a restart of the 
dispatcher and cycle, I verified that 
 1) the dpcs_init had in fact completed normally as indicated in 
the pcdaqdpcs3-dpcs.log file and
 2) all the outputs and subsequent actions and waveforms during the
no-power shot were normal. 
Based on this, I instructed the operators to bypass the critical
init failure warning STATE and proceed with the shots while T&J
investigated the cause of the spurious messages. We ran this way,
without incident, for shots#5-8.

After shot#8, Tom and Josh had determined that the init action 
failure was due to the presence of the IDL error state, and that
this was due to an mdsvalue error someplace in the dpcs_init code.
They didn't and still don't understand why this had never mattered 
before and was now mattering, but we started working on a workaround.
Josh put a new line into the dpcs_init procedure in 
/usr/local/cmod/idl/dpcs2/dpcs_startup.pro to do a help,/str,!error_state
just after the call to the user_init_procedure. (I think he also
uploaded to CVS; need to check). I stuck a 
message,/reset into the end of the dpcs_fizzle_init.pro routine,
since a message from that routine was showing up in the logfile. However,
on a test shot we found that this did not get rid of the -5 error
condition. Looking deeper into dpcs2_init_procedure.pro we found that
the setup of the V waveforms involved a loop over vnodes[1:32] which
used mdsvalue(,/quiet,stat=stat) and checked the stat return. In 
fact, a lot of these do fail because PCS only fills in the first 16,
and not all of the second group are defined. I stuck
in an else clause that printed the status on failure and then
did a message,/reset to clear !error_state. This succeeded in 
removing the error condition, and subsequently allowed the shots to 
proceed without further critical init failures. 

However, Tom pointed out that the fifo_serve code that is reporting 
the status to the mdsip server is in fact sending the value of the 
obsolete sysvar !err, rather than !error_state.code, and message,/reset
does not set the value of !err to 0 (a pseudo-bug in IDL, since
the !err is obsolete but the documentation claims it should still work
as previously. It turns out, amazingly enough, that doing a 
help,/str,!error_state seems to reset the value of !err to that
of !error_state.code, and therefore the diagnostic statement that Josh
inserted (at Tom's suggestion) into dpcs_init was in fact necessary to 
make the patch of the dpcs2_init_procedure code succeed. 

Josh will change the fifo_serve code to use the !error_state.code 
variable instead of the deprecated !err, and hopefully change
anything else of the cycle-related software that uses this obsolete 
sysvar. Probably this will happen on Monday? Meanwhile, we still don't
know why the presence of this rather benign error state is now being
considered evidence of failure, when it never was before. This seems 
wrong, since lots of code must encounter mdsvalue errors without clearing
the state, but nevertheless finishing gracefully and successfully. This
behavior should be tracked down and reconsidered.

Also still have hards, which dump around the time of the marfe.
looks like an injection around 0.15, small bite out of Ip 
good bd time, no obvious bounce, decent burnout.

Shot#4: repeat (no DPCS changes)
IGT@INIT=2.0e-6
Actmon hung in init, cleared after 2:
Tom claims dpcs3 rebooted, it completed init, 
I see no reboot messages in the log file, but it's only been up 
for 2minutes. The dpcs job is there and running.

Shot#3: Increase early seg2 current rise (point at .282 from 750 to 800kA)
IGT @INIT=1.6e-6
plasma full length. 
No hards, no marfe. 
NL04 feedback is calling for gas from about 0.3sec to 1.3sec when
the demand target goes negative. Density rises slightly during 
pulse, basically at target value of 0.9e20. 
M3/M4 seems to be coming back down, peaked at .55 before shot.
M16 still ratcheting up, 
H/D up to ~0.2

Heat footpring diagnostic is having timing problems, so display
is showing cool everywhere. Wide1 video (and others?) have been otl
all day, wide2 is there (tilted view).

Next: repeat (no DPCS changes)

Jul 9 2009 09:53:13:427AM1090709004Steve Wolfe
Shot#4: repeat (no DPCS changes)
IGT@INIT=2.0e-6
Actmon hung in init, cleared after 2:
Tom claims dpcs3 rebooted, it completed init, 
I see no reboot messages in the log file, but it's only been up 
for 2minutes. The dpcs job is there and running. 
Restart message in the logfile showed up very late, but it's there
now.
There is also a message from dpcs_realtime that the
variable  STRLEN: Variable is undefined: USER_RT_PROCEDURE (DPCS_PARAMS).
which makes sense since the init was done before the reboot.

Should be ok for next shot. Need to understand why the reboot happened,
eventually. 
Took a dpcs test s\hot - looks good to go.

Jul 9 2009 10:10:18:583AM1090709004Steve Wolfe
Shot#4 (second edition): repeat of 3 (no DPCS changes)
IGT@INIT=9.5e-7
Got a critical failure on dpcs2 init. 
Need to see what's going on now. 

Take another no power
The dpcs3 logfile indicates that the init completed fine
but the actmon claims something called 
CMOD::top.hardware.dpcs:dpcs2 init action failed. 
It's dpcs2 server not dpcs3. Apparently this is the FFT?
Why is it in cmod instead of RF? 
It isn't. This was DPCS_SERVER error and it is for the 
dpcs system. 


Jul 9 2009 10:14:08:850AM1090709004Steve Wolfe
Shot#4: The log file indicates that the dpcs completed normally.
However, the action monitor really did say that it had a critical
error on the DPCS_SERVER on the dpcs2 init. Note that this refers
to the device type dpcs2 not to pcdaqdpcs2 and has nothing to do
with rf or fft. 

Josh is apparently checking into why it claimed a failure.
He wants cycle restarted.




Jul 9 2009 10:36:50:113AM1090709005Steve Wolfe
Shot#5: repeat of shot#3 I hope.
Again a crit init failure on init of dpcs
but log file says it's ok. Bypass and go
Note that I got the same error on the test_init_dpcs2 
test shot 1090709101, as I have been for a qhile.

plasma disrupts at 1.78 sec in rampdown. 
No marfe no hards. good startup. 
M3/M4 hanging at .55, M16 still ratcheting up.
H/D~0.21
Next: I'm going to start dropping the density target.

Jul 9 2009 10:50:50:787AM1090709006Steve Wolfe
Shot#6: Reduce nl04 from 9e19 to 8e19
T&J still looking at why we're getting critical failure
DPCS init is fine in logfile, bypass and go

plasma full length
density rising as gas drops after 1sec, ends up at 9.2e19
by EOF. We're still running off the wall, I guess.
M3/M4 rising again after #5, now up to 0.66
H/D between .25 and .2, down and up and down during shot
Startup still looks good, Ip/Bz increasing a little

Next: Decrease nl04 demand to 7e19

Jul 9 2009 11:11:20:583AM1090709007Steve Wolfe
Shot#7: Decrease nl04 demand to 7e19
ITG@INIT=? wasn't looking
fizzle.
fast current rise to nearly 90kA, 
moving up fast. And it knows it, no magnetics error messages
Looks like the oh2's are trying
to compensate, they are following the demand. 
Don't understand what happened, and I want to before the next shot

Jul 9 2009 11:24:11:693AM1090709007Steve Wolfe
Shot#7: I see no magnetics errors. 
The zcur is moving up before the zcur gain comes on at .02sec
so it isn't the zcur feedback. 
The Br0 is going positive, starting at .01sec, and it's not clear 
why. Feedback seems to be trying and failing to compensate.
Index looks possibly too high.

Next: decrease br0, increase pg4, cross fingers


Jul 9 2009 11:58:40:980AM1090709008Steve Wolfe
Shot#8: decrease br0 from .0015 to .001, 
increase pg4 from 13 to 15, cross fingers
plasma full length 
again density starts up at 0.85sec

We are trying to track down why the dpcs init software is
suddenly throwing spurious errors, after the reboot. 
I have edited dpcs_fizzle_init so that it clears the !error_state
at the bottom, because Josh thinks that may be it. 

He's editing /usr/local/cmod/idl/dpcs2/dpcs_startup

Jul 9 2009 12:31:45:883PM1090709009Steve Wolfe
Shot#9: Just a repeat, no dpcs changes to shot, 
several changes to dpcs software.

plasma full length
Density is still rising after 0.85sec, halpha goes up
too. What's it interacting with? 
That's about when EFIT says the outer strike comes off 
the floor onto the plate. OK, raise ZXL earlier. 


Jul 9 2009 12:43:03:180PM1090709010Steve Wolfe
Shot#10: raise zxl from -.015 to -.005
plasma full length
Now the density is flat at 7.2e19, and the gas is puffing weakly 
throughout. I seem to have moved away from where it was
sourcing? I expected the opposite response, but...

Next: repeat. Brian will poke probes

plasma full length
Density flat at 6.6e19, gas puff hovering near zero for most of pulse.
M3/M4 up to .9, H/D between .25 and .3 during flattop
Startup still looks good, but Ip/Bz is pretty high and the
zmeter burnout is fast. I'm thinking of increasing pg4 again.

Shot#15: Repeat, no dpcs changes
plasma full length
M3/M4 climbing between pulses again, was at 1.0 before 15;
I guess this means it's bringing out the H.
H/D between .3 and .35 in flattop, rising in rampdown

Next: Repeat after cell access

Jul 9 2009 02:11:08:070PM1090709016Steve Wolfe
Shot#16: Repeat, no dpcs changes
plasma full length. Just chugging along. 
Brian's stuff is working on this shot (except for one 
module he removed fromt the cell whose overcurrent light was on
continuously). The heat footprint display updated, shows 50C
rise on the outer plate near/above the efit strike; limiters look
pretty cool, ~10C near midplane of GH.

M3/M4 still around 1, H/D~0.3

Next: repeat, let BLAB clean probes.

Shot#21: Start rxl at +.005 instead of 0.
IGT@INIT=2.0e-6

Even less hards than last time, and the injection seems gone or at
least smaller. However the startup is developing a hesitation
around 15msec and then a surge around 18-22msec.

Next: drop pg4 by 1msec


Jul 9 2009 03:26:00:273PM1090709022Steve Wolfe

Startup has a bit of hesitation, better drop the fill again. 
No H/D reading until the rampdown marfe because of low signal.

nl04 down to 6.6e19, so it must have been the pg3 feedforward

Next: Now try a couple of inner wall shots.

Shot#29:  Now try a couple of inner wall shots.
Seg3 off, seg2 on
Clearin from 0. to -.015 (shot#23 had 11mm inner gap)
rcur from .658 to .65

plasma full length
a few (very few) hards, didn't look limited though.
Very marginally limited, should have gone farther.

Next: make clearin more negative, go to 1MA (per ESM request)

Jul 9 2009 05:18:50:477PM1090709030Steve Wolfe
Shot#30: clearin from -.015 to -.02, go to 1MA (per ESM request)
Leave rcur alone, since there's a big outer gap already.
Ip to -1.e6
IGT@INIT=2e-6, maybe should have dropped the fill again?
plasma to 1.45sec, disrupts at EOF, Ip had dropped to 850kA.
It was definitely limited this time, big marfe before the disruption
loop voltage was around 1.8 in flattop, looks like OH1 ran into the
rail, density ran up to nl04=1.1e20 (program value was 6e19,
gas puff was off for whole shot.
M16,M28,M14,M18 all up by about an order of magnitude
M3/M4 only up a little, to 1.3 or so.
H/D was around .5 during the shot. 
Ten minutes after the shot the IGT reading is 2.8e-6, high but 
not humongous as it was on 1MA disruptions last week. Of course,
this wasn't really a 1MA disruption thanks to the railed power supply.

END OF RUN.
