MP#555: PF Error field evaluation and compensation
SL: wolfe
PO: Rowan

This experiment calls for long flattop single coil PF pulses under DPCS
control for the purpose of evaluating the non-axisymmetric error fields
arising from tilts or shifts of the PF coils.  The last time such tests were
done was on 1030717. 

We will also take one long flattop TF pulse (under PLC control) in order to
improve the evaluation of the toroidal tilt of the magnetics sensors, several
of which seem to have changed significantly since reassembly.

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. 

We will also test the a-coils using non-standard tap settings. One change of
A-coil taps is called for during the run.

If/when we finish the field evaluation, the run will go back to MP#298a plasma
cleanup runs. Therefore, we should have overnight ECDC and load the gas plena
as for a normal plasma run, but all valves disabled. 

Special engineering instructions: Start with power systems as on: 1030717007
(OH1 only, EF3 Aux power OFF) 
Fizzle detector on at 2.2sec, off at 2.3 sec for all shots
Note that all PF shots will use the same settings for fizzle detector and all
those without EF3 will want the EF3 AUX power off. 

Acoil: +Btop -Bbot -Gtop +Gbot (Non-standard) Hybrid Enabled (OFF for 1st shot)


Shot sequence  plan MP#555
----------------------------------
Note to Physop: trying to load shots from 2003 will bring up the configuration
warning, and a warning that the DPCS tree will not be superceded. The present
DPCS tree should be fine, but the dpcs_fizzle routine should be turned OFF for
these power tests. Remember to turn it back on if we go on to run plasmas in
the afternoon. Wires 4 and 6 (zxl, bz_0) in segment 1 should be zeroed to 
avoid warnings about bad sensors in these predictors, which aren't used
for these shots anyway. 

The waveforms for steps #3-10 are the same as loaded from
1030717010, so you just need to tell the engineers which coils to energize
(and/or which shots they need to copy from). If we do steps 11 and 12
(separate EF3 and EF4 coils) you can keep the waveforms but need to modify the
observers to look only at the active coil. 

1) Load  from 1030717007 (OH1 2sec pulse at +20kA)
2) Load (or copy trace) from 1030717010 (OH1 swing -20 to +20)
3) "" 1030717008 (OH2U +20kA, 2sec flattop)
4) "" 1030717009 (OH2L +20kA, 2sec flattop)
5) "" 1030717011 (EF1U +5kA, 2 sec flattop)
6) "" 1030717012 (EF1L +5kA, 2 sec flattop)
7) "" 1030717013 (EF2U -4kA, 2 sec flattop)
8) "" 1030717014 (EF2L -4kA, 2sec flattop)
9) "" 1030717005 (EF4U/L +4kA, 2 sec flattop)
10) "" 1030717006 (EF3U/L +10kA, 2sec flattop) EF3 ON
11) If results from 9 and/or 10 are sufficiently different from the
corresponding shots 1030717005 and 6, then it will be necessary to break down
the bus and take pulses with the coils individually. Otherwise proceed to #13.

Note that the disconnected coil should be terminated in a varistor to
avoid induced currents; check engineering records for 1030717001-004 to see
what was done. Also, the notes indicate that it is necessary to fool the I2t
circuit to allow these shots to be taken.  
  11A) 2 sec EF4U pulse, +4kA. Use waveform as on #9, change predictor. Compare
       to 1030717001. Note EF3 Aux power OFF.
  11B) If necessary, 2 sec EF3U +10kA pulse. Same waveform as #10, but modify
       predictor. Compare 1030717002, which has modified waveform for gentler
       rampdown.  
12) For next shot, again reconfigure bus for Lower coil(s) only 
  12A) 2 sec EF4L pulse, +4kA (note predictor change. EF3 Aux power off.
       compare 1030717003 
  12B) If necessary, 2 sec EF3L +10kA pulse (note predictor change from 11B)
       compare 1030717004 
13) A-coil only pulse [+Btop -Bbot -Gtop +Gbot] program 4kA 
14) Reconfigure A-coil to [+Btop +Bbot -Gtop -Gbot], program 4kA 

15) If cases 11 and 12 were run, reconfigure the bus for normal operation and
repeat shots 9 and 10 to confirm connection.

16) Long pulse TF-only pulse (PLC control ok) as on 1080523029. Compare
    results to existing magnetics::top.bp_coils:btor_pickup and apply for
    future shots. Note that this may necessitate predictor recalculations. 

For steps #1-10, and 11-12,15 if necessary, monitor BP difference signals and
compare to corresponding shots from 1030717 where the same signals are
available. Detailed analysis to be done post-run using
/home/wolfe/idl/cmod/error_fields/diff_bpcoils_ts.pro .

Run Summary for MP#555 on Thursday, July 2, 2009
SL: wolfe
PO: Rowan
EO: Parkin, Cochran, Byford

We completed all the PF tests called for in the run plan. 
Because the signals on the EF4U/L and EF3U/L showed significant
differences on some sensors from the reference shots in 2003, we
ended up taking pulses with the individual coils. We also got the 
long pulse TF test for updating the BTOR_PICKUP values on all the
BP coils.   The time required
for reconfiguring the bus was greater than anticipated, and as a result
we had to defer the A-coil pulses with the 
B and G coilset. The A-coil taps should be set back to the normal
configuration before Tuesday's run.  

Eyeball analysis of the results with OH1, OH2U, OH2L, EF1U and EF1L
indicate small if any differences from the same cases in 2003, implying
that the removal and reinstallation of these coils did not result in 
a major change in the non-axisymmetric error fields. This conclusion is
tentative, pending detailed analysis of the complete dataset. The variation
in the signals using the outboard coils EF3 and EF4 is likely due to 
diffences in the sensor response, rather than real changes in the 
location of these coils, but I need to do the full analysis to be sure. 

The final test pulse (#14), of EF3L only, ran to the PLC limit and tripped the
timed overcurrent fault because the feedback observer was inadvertently
set to look at the EF4L current instead of EF3L. There was substantial
current in the varistors at turn-on and turn-off because the supply was
essentially driven to its voltage limit. No current was observed in the
disconnected coils, so the induced voltage on these was not enough to 
make their varistors conduct. 

The EF4 and EF3 bus were reconfigured to their normal connections, and 
PLC test pulses (#15,16) taken to verify the change. It was necessary
to reconfigure the bus and remove the I2t force in order for the cooling
to operate normally over the weekend. 

Shot#17 was the TF test, taken at 17:30. Thanks to all who stayed late
to get this completed!

Data was acquired for MP 555. No data was taken for MP 298A.
There were 15 shots. During these shots, OH1, OH2U, OH2L, EF1U, EF1L, EF2L, EF2U, EF4U, EF4L, EF3L, EF3U were all pulsed separately.
An error in DPCS setup on shot 014 caused the EF3 to run up to the PLC limit. The EF3 lower bus rogowski returned 11 kA. The demand would have been 10 kA. EF3 was tested under PLC control and found to be okay.

Set up monitor scopes, two copies of ~/scopes/scope_bp_corrected_n1.dat
to monitor difference waveforms. These are the primary dataset for the
analysis of this experiment. 
Also scope_bp_corrected.dat and scope_bp_corrected_17-26.dat just to
check unsubtracted signals make sense, and check for sensors that may need
zapping during the day. 

The good n=1 pairs based on scope traces from 1030717007
(20kA OH1 pulse) were:
  Pair         Old value   New Value
 --------     -----------  ----------
 BP04_BC-GH      +.015 ?
 BP06_BC-GH      -.008

 BP26_BC-GH      -.011?
 BP11_DE-JK      -.001
 BP12_DE-JK      -.002
 BP15_DE-JK      -.001
 BP16_DE-JK      0

 BP19_DE-JK      -.005
 BP21_DE-JK      0
 BP22_DE-JK      +.003
 BP24_DE-JK      +.016
 BP26_DE-JK      -.005

Based on the defaults in analyze_pf_1030717.pro the following were 
"bad": 
badbp = ['BP01_DE','BP01_GH','BP02_DE','BP02_GH','BP03_DE','BP03_GH','BP04_DE','BP05_DE',$
         'BP05_GH','BP06_DE',$
         'BP07_DE','BP07_GH','BP08_DE','BP09_DE','BP10_DE',$
         'BP14_JK','BP17_BC','BP18_BC',$
         'BP20_DE','BP22_GH','BP23_GH','BP24_GH','BP25_GH','BP23_DE',$
         'BP06_BC','BP25_JK', $
         'BP13_JK']
so I've eliminated the pairs involving those from the above table, even
though the signals looked ok on the scope. Most of these should be
available for today, plus a bunch of others. However, note that the 
gains on (at least) BP08_GH-BP13_GH (*) will be different, since they may
be on different integrators, so the between-shot comparison will be problematic.

These look very similar, except for some that may be broken.
Move on to the oh1 swing case. 

Some of the new coils have strange looking transients before
and after the flattop (on the diff signals). Need to see what's 
going on. 

Jul 2 2009 09:33:18:463AM1090702002Steve Wolfe
Shot#2: OH1 double swing (compare 1030717010)
 Only got -12kA on forward swing. 
 That seems to be what we got on 1030717010 as well. 
Difference traces look very similar
There's a glitch at .812sec, crossover.

Ok we didn't get what we asked for, possibly switch didn't close.
But this is the same thing that happened in 2003, so move on.


Jul 2 2009 09:45:18:230AM1090702003Steve Wolfe
Shot#3: OH2U 20kA flat (compare 1030717008)
 This shot had very small diff signals on the reference shot, 
Biggest was on bp06_bc-gh, which seems to be broken or have wrong
integrator signal now. Have to rely on comparison to 04 and 08 and
not seeing big signals on others for between-shot comparison. 

These traces also look very similar. Bp04bc-gh diff is smaller than in
1030717008, but it was noisy then. No large signals where they were small
before, and the bp08 and bp24_de-jk look quite similar. Now we have
several more signals that are responding, which should provide additional
data on this coil tilt/shift, especially in the de set. 

Bob is going to check on the
integrator boards on bp06_gh bp07_gh, which seem to be wrong in the
tree. 

Jul 2 2009 09:56:07:340AM1090702004Steve Wolfe
Shot#4: OH2L 20kA flat (compare 1030717009)
The big signals on the reference are on bp22_de-jk, bp24_de-jk. 
Note that bp23_de is marked bad, that one also seemed to have
responded on the ref shot. The 24 pair looks suspiciously large
in the reference. This may have been a gain discrepancy?

Ok, similar signals on bp22_de-jk (+.01) and bp24_de-jk (-.02)
Have additional data on the bp24-26bc-gh pairs that we didn't have before.
Looks good. 

Move on to EF1's.


Jul 2 2009 10:13:46:590AM1090702005Steve Wolfe
Shot#5: EF1U +5kA flattop (compare 1030717011)
Expect major signal on bp04_bc-gh (and the 06 pair, but that one still
has a gain problem), noticeable on the 08 pair, mostly flatlines elsewhere.
The new upper DE coils should improve the diagnosis on this coil a lot,
but formerly we concluded there wasn't much effect. The EF1's are 
the other coils that were removed and replaced during the disassembly.

Ok, the bp04_bc-gh signal is -.008, compared to -.012 in 2003. The 08 pair
is -.002 compared to -.003 (roughly); the 12_de-jk are both around +.002. 
Similar but maybe a little smaller than the reference. There are visible 
signals on several of the new pairs.

Next will be EF1L 


Jul 2 2009 10:26:04:323AM1090702006Steve Wolfe
Shot#6: EF1L +5kA flattop (compare 1030717012)
The reference has large (-.007 or so) signals on bp20_bc-gh and bp21_bc-gh
also signals on bp21_de-jk and bp24_de-jk. 

The bp20 and 21 bc-gh differences look very similar to the reference shot. 
However, bp21_de-jk is opposite polarity (-.006 vs ref of +.005); 
bp24_de-jk is -.003 vs ref of -.005. This may indicate a change of tilt
or it could be a sensor issue. Won't know till I get the analysis done. 

Move on to the EF2U case. 

Jul 2 2009 10:40:14:760AM1090702007Steve Wolfe
Shot#7: EF2U -4kA flattop (compare 1030717013)
This one had long transients in some sensors that we never figured out.
Biggest flattop signatures were on BP09_bc-gh, BP12_bc-gh, bp12_de-jk
Notice we got ~200A of unbalanced current in the EF4's on this one.

bp09_bc-gh again has a big (-.02) negative signal, signals on bp10 and 12 bc-gh
pairs look similar, as di bp12_de-jk. The transients look different
(opposite sign) on bp11 bc-gh and de-jk. Since we didn't understand the 
transients, I'm not sure what this  means. We know the coil pack
didn't move relative to the vessel, so it's not likely a coil change, 
maybe something in the induced current path.

Move on to the EF2L 



Jul 2 2009 10:47:15:103AM1090702008Steve Wolfe
Shot#8: EF2L -4kA flattop (compare 1030717014)
Major signals on the 15-20 pairs, especially bp18_de-jk around +.015
Of course, this is just where the signals are biggest, so the apparent
diffs are mostly just differential gain, probably.

Signals on those coil pairs look almost identical. 

Move on to the EF4 case.



Jul 2 2009 11:11:01:793AM1090702009Steve Wolfe
Shot#9: EF4 U/L 4kA (parallel) compare 1030717005
This one will determine if we need to separate the ef4 bus later.
The reference shot has noticeable signals on most pairs. 

The signals look very similar. There is a differnce in magnitude on
bp10_bc-gh, but this could be different integrators. bp26_bc-gh
is +.005 now, vs -.001 in the ref, but the 26 coils have been flakey,
so I'm not sure this is real. There is also a small discrepancy 
in the bp19 levels (-.003 vs -.005 in the ref) but the bc-gh and de-jk
values match in each. 

Move on to the EF3 case. If it doesn't indicate we need to 
split the bus, I won't ask for the EF4 to be split either. 


Jul 2 2009 11:56:52:450AM1090702010Steve Wolfe
Shot#10: EF3 U/L 10kA (series) compare 1030717006
This one will determine if we need to separate the ef3 bus 
The reference shot has big difference signals on most pairs. 
If the slight discrepancies on the previous shot were due 
to changes in gains, there should be similar effects on this one.

Again there is a change in the bp26 diff signals, much bigger in this shot 
than in the reference. I think this is a gain change issue or a sensor
problem. There's also a change in the bp21de-jk and the 22de-jk is only
half as large in the present shot as in the reference. Also the bp11_de-jk 
transient seems to go the other way.

I think we need to separate the bus and do the EF3U and EF4U separately.
There will be a significant delay while this is done. 

Note that the signal on bp06_gh has been all over the map today, 
varying by large factors either greater than or less than the other
bp06 loops. This does not seem to be an integrator issue, unless the
board itself is changing (maybe a bad contact?). More likely the loop
or connector is bad. 

Jul 2 2009 02:22:12:167PM1090702011Steve Wolfe
Shot#11: EF4U 4kA (separate) compare 1030717001 (timing a little 
different). The expected signature is opposite sign signals on 
bp11&12 pairs for bc-gh (negative) and de-jk (positive).

Data looks very similar to 1030717001
Looks good. Go to step 11B, the EF3U-only test


Jul 2 2009 02:33:15:323PM1090702012Steve Wolfe
Shot#12: EF3U 10kA (separate) compare 1030717002 (timing a little 
different). 
Signals mostly look similar to the reference shot. There are magnitude
differences on the bp26 coils, as there were on the combined tests.
Also, bp11de-jk has opposite sign, some other diffs will need to be
sorted out in the analysis.

Now will reconfigure for lower coils only.
This will take another access interval

Jul 2 2009 04:13:58:963PM1090702013Steve Wolfe
Shot#13: EF4L 4kA (separate) compare 1030717003
Expect relatively small difference signals on outboard 
coils, mostly below midplane (bp14-20)

Signals look ok, sign is different on bp25_bc-gh

Next: Ef3L only test

Jul 2 2009 05:11:28:510PM1090702014Steve Wolfe
Shot#14: EF3L 10kA (separate) compare 1030717004
EF3 current looks bad at turnoff
Ran to 11kA.

Observer was set on EF4L instead of EF3L, so it never saw
current for feedback and kept calling for more, ran up to PLC
limit. Breaker opened on timed overcurrent fault. 
Had some varistor current on the turn-on and turn-off transients
because the voltage slammed on and the fault inverted it. 
Nevertheless, the difference signals look reasonable, should be ok
for analysis.

There was a short pulse on the chopper at t=0, and EFC got to 1.7kA
at t=2.1sec when the EF3 shuts down.
 Not at all sure how that happened. There was 0. 
chopper demand from DPCS, but the supply shouldn't have been 
energized. 

Will put the bus back to normal, take PLC shots to test. 
We will skip the TF and A-coil tests today. Can get TF test on 
Tuesday, do without the acoil test for now.

Shot#15: With the bus reconfigured for normal operation
(EF4U/L in parallel, EF3U/L in series)

EF3 PLC test. 
Looks ok. 
Next: EF4 PLC test

Shot#16: With the bus reconfigured for normal operation
(EF4U/L in parallel, EF3U/L in series)

EF4 PLC test -1KA (forward bridge)
Got EF4 and induced EF3 current. 
Looks good

Jul 2 2009 05:41:04:167PM1090702017Steve Wolfe
Shot#17: Take a TF test based on 1080523029 to complete the
power pulses for the original sequence. Move invert time in to 1.5sec
from 2.0, fizzle detector at 1.8s

That looks good, can use this to set the Btor pickup values
on all the BP coils. It looks like several need updating.
