MP 552 -- This experiment will test the new multi-processor multi-timescale capabilities of pcdaqdpcs3 with an anti-saturation adaptive control routine. The routine offers a possible mechanism to avoid the saturation of the OH and EF control currents during a discharge: the initial target plasma is interpolated in real-time to a neighboring equilibrium when a control current is approaching saturation. Because of the significant real-time computation of this routine, a new control system with multi-processor capabilities has been set up and will be tested in the experiment.

Detailed experimental plan:

1) Load 1080108006 as the target plasma.

2) Run a couple of shots and monitor the outputs of the new control system. Tune the control setup for the target plasma. EF2L should run into its rail towards the end of the discharge.

3) Ask for Interface Room access. Disconnect from the live patch panel the SCSI cables coming from the output cards of dpcs1. Connect to outputs 1-16 on the live panel the SCSI cable coming from dpcs3.

4) Modify the CMOD tree:
4a) open CMOD tree -1;
4b) turn off \top.admin.dpcs3

5) Modify the HYBRID tree:
5a) open HYBRID tree -1;
5b) change the server name for
.HARDWARE.DPCS:DIO2:INIT_ACTION
.HARDWARE.DPCS:DI02:STORE_ACTION
from pcdaqdpcs1:mdsip_analysis to pcdaqdpcs3:mdsip_analysis
5c) change the server name for
.HARDWARE.DPCS:DPCS2:INIT_ACTION
.HARDWARE.DPCS:DPCS2:RT_ACTION
.HARDWARE.DPCS.DPCS2:STORE_ACTION
from DPCS_SERVER to pcdaqdpcs3:mdsip_analysis

6) Run a no-power shot to verify that everything is in order.

7) Run the target shot 1080108006 without the anti-saturation routine, i.e. single processor. Verify that the new system works fine.

8) Load the anti-saturation observer routine into PCS:
8a) click Observers;
8b) add the procedure "dpcs_current_saturation_2p_obs_init"
8c) click on Observers again, then on the routine;
8d) set the parameters (IDL expression) to: {SHOT_SAFE: 1080509700,IC_BUFFER_DEPTH: 10,TIME_FOR_ACTION: 100.000,INTERPOLATION_TIME: 200.000,USE_ENG_RAILS: 1}
8e) set the Switch Times to: [0.5,2.0]
8f) apply and dismiss.

9) Load the anti-saturation controller routine into PCS:
9a) click Controllers;
9b) add the procedure "dpcs_current_saturation_2p_ctrl_init"
9c) click on Controllers again, then on the routine;
9d) set the Switch Times to: [0.5,2.0]
9e) apply and dismiss.

10) Run the shot and change the anti-saturation routine's parameters as needed. Observe how saturation events are triggered and the initial target is interpolated to the safe equilibrium. Verify that the control currents are not saturating.

11) Revert trees to the original settings:
11a) open CMOD tree -1;
11b) turn on \top.admin.dpcs3
11c) open HYBRID tree -1;
11d) change the server name for
.HARDWARE.DPCS:DIO2:INIT_ACTION
.HARDWARE.DPCS:DI02:STORE_ACTION
from pcdaqdpcs3:mdsip_analysis to pcdaqdpcs1:mdsip_analysis
11e) change the server name for
.HARDWARE.DPCS:DPCS2:INIT_ACTION
.HARDWARE.DPCS:DPCS2:RT_ACTION
.HARDWARE.DPCS.DPCS2:STORE_ACTION
from pcdaqdpcs3:mdsip_analysis to DPCS_SERVER

12) Have Interface Room access and connect the SCSI cables back to their initial configuration.

ECDC overnight and bake at 60 C.

NOTE: WE MAY NEED A FEW MINUTES IN THE CELL TO PRESSURIZE THE GAS JET
  SYSTEM FOR THIS HALF-DAY DISRUPTION RUN.

Power systems as on 1080320002 (1.0 MA, 6.2 T, LSN, nl_04=0.25e20 m-2,
   cryopump on, LH target, noticeable synchrotron emission)

A-coil configuration: normal [+Dtop -Dbot -Jtop +Jbot] and enabled.

Gas Setup:
   fill B-Top            with  6 psi D2  Hybrid enabled  (PG4)
   fill B-side lower     with  1 psi Ar + 2 psi Ne   Hybrid DISABLED (PG1)
  leave B-side upper     as is           Hybrid disabled
   fill B-main (C-side)  with 40 psi D2  Hybrid enabled  (PG3)
No NINJA for this run.

Enable the following, assuming no vacuum problems:
ECE, Z-bolo shutters, VUV

Necessary diagnostics:
  LH hard x-ray array
  WIDE1 and WIDE2 video cameras
  Z-meter array
  SXR arrays
  Plasma current Rogowski

-------------------------------------------------------------------------------
ICRF setup: no ICRF today

LHCD setup: P_LH >= 0.7 MW, t=0.90-1.05 s; 90 deg phasing or whatever is
  best for current drive for the given plasma conditions

Cryopump: warm for 1st shot, but ready to be cooled at a moment's notice

DNB: no

LPI setup: normal pellet size; will fire at t=1.000 s.

Disruption gas jet: 15%/85% Ar/He at 50 bar; will fire at t=1.000 s.
-------------------------------------------------------------------------------
Run plan:

Turn on LH at t=0.90 s and off at t=1.05 s.  If the density stays low
(~3e19 m-2), this should briefly create a synchotron-emitting relativistic
runaway beam (a la shot 1080320002 at t=0.70-0.75 s).  If the density does
not stay low, then turn on the cryopump for subsequent shots.

At t=1.000 s, inject a normal-size lithium pellet.  Look at Ip trace, hard
x-rays, video cameras, Z-meter, etcetera to determine if runaways are
produced prior to the disruption and/or during the current quench.

Based on the observations in FT-U, the creation of runaways has much higher
probability when using an LH seed, but it's still less than 50%.  Therefore
each set of conditions should be tried several times, as time allows.

If there is no sign of relativistic runaways, try the following options, in
the order listed:
 1) program in a small Ip ramp just before the disruption (to cause loop
    voltage to take a jump up)
 2) try a Bt rampdown to get a q=2 disruption (Bt would have to be ramped
    down to ~3 T)
 3) try an inner-wall-limited plasma configuration (a la FT-U)
 4) try a gas jet disruption

MP552 -- Successful first half run. Notes:

1) The order of the shared memory read and write operations on the master side used to be master reads -> master writes -> slave computes and writes the new results. This order does NOT work, because as the master reads the interpolated values of p_out and passes them over to the slave again for a further interpolation, the all process results in a faster interpolation... and wrong! Solution was to change the order of operations on the master side to: master writes and subsequently reads, while slave reads, computes and writes the new results. This new order might generate conflicts on accessing the results of the computation of the slave and will need further analysis. However, it worked in the experimant. This version of the code is now in CVS.

2) DPCS3 came online at shot 009 with a no-power shot and then controlled the plasma in shots 010-016. No problems in transitioning from DPCS1 to DPCS3.

3) The anti-saturation routine was operating in shots 011-016.
- 011 had too fast interpolation_time = 20ms, but the routine seemed to be doing the right thing. time_for_action = 10ms
- 012 was interpolating to the same equilibrium as the original one (a mistake in the setup), so no changes during the discharge, but the routine seemed to be doing the right thing.
- 013 was interpolating to a different equilibrium for which RXL = -4cm, works fine! interpoaltion_time = 100ms, time_for_action = 10ms
- 016 was interpolating to a different equilibrium for which RXL = -2cm, works fine! interpoaltion_time = 100ms, time_for_action = 10ms

4) We understood that it is important to pay attention at the number and the location where the pcs and dpcs trees of the safe equilibrium shot_safe are saved. It is also important that when creating the corresponding Hybrid tree the settings in the pcs and dpcs trees don't get overwritten.

5) No problems in transitioning back from DPCS3 to DPCS1 in shot 017.

Session leader run summary for Wednesday 21 May 2008 (afternoon)

MP530 Disruption runaways studies

Session leader: R. Granetz/D. Whyte
Physics operator: E. Marmar

The focus of this half-day run was to try some additional ideas to generate
relativistic runaways during disruptions that we didn't get to try during
our previous run on 1080220.  The basic idea still is to use LHCD to
produce a seed population of fast electrons (100-200 keV) prior to the
disruption.  But unlike last time, we decided to keep the LH on right into
the disruption.  In addition, this time we tried two different ways to
generate prompt, reproducible disruptions: (1) use injection of
normal-sized lithium pellets, and (2) q=2 disruptions.  And finally, in
this run we ran at very low density (nl_04=0.35e20 m-2) in order to
generate a relativistic propulation before the disruption (using the video
camera images to look for synchrotron emission), and we also tried
programming in a step jump in plasma current just before triggering
disruptions.

The result is that although the LH ran well (0.7 MW), and we were able to
create plasmas exhibiting synchrotron emission prior to the disruption,
there were still no clear examples of relativistic runaways during the
current quench.  There was one shot (1080521028) that had an unusual 'bump'
during the current quench, as well as some non-thermal ECE emission during
the current quench, but the quench time was not significantly stretched out
in time.

We still haven't found a reliable way of triggering prompt, reproducible
disruptions under conditions that are amenable to relativistic runaways.
The lithium pellet doesn't penetrate well when there are lots of runaways.
The q=2 method was tried, but the plasmas all disrupted early, well before
the TF had ramped down enough, for unknown reasons.  We also had a number
of fizzles.

So obviously we'll have to rethink our approach.  The q=2 method might
work, as long as the plasma doesn't die early.  The ability to produce
plasmas on demand with synchrotron emission before the disruption is now
proven, and the step jump in Ip seems to help.  We didn't get a chance to
try running limiter plasmas, a la FT-U.  And perhaps more LH power might
help as well.

Anti-saturation routine is triggered at 0.67s by EF2L, but too fast... why??? Next shot change interpolation_time to 600.
May 21 2008 11:33:29:883AM1080521010Marco FerraraDPCS3 is controlling the plasma.

Found a bug in the anti-saturation routine (off in this shot)
May 21 2008 12:18:51:840PM1080521011Marco FerraraThe anti-saturation routine is running but too fast. Next shot change interpolation_time from 20ms to 100ms. Change also the shot_safe RXL to -4cm from -2cm.
May 21 2008 12:19:44:620PM1080521012Marco FerraraWe made a mistake, we are interpolating between the same equilibria. Works, but not useful. Fixed for next shot.
May 21 2008 12:28:30:707PM1080521013Marco FerraraWorked!! EF2L is pulled out from the rail. Next shot try RXL of safe equilibrium -2cm, interpolation_time=100ms
May 21 2008 01:04:52:313PM1080521016Marco FerraraThis shot try RXL of safe equilibrium -2cm, interpolation_time=100ms. Works!!

Ought to be careful about shot_safe number and setup of hybrid, dpcs and pcs models.
May 21 2008 01:40:38:957PM1080521016Robert GranetzShot 17 -- For the first shot we will have LH at t=0.95 s, but no lithium pellet injection.
May 21 2008 01:09:39:847PM1080521017Robert GranetzI signed on as session leader starting with this shot.

Cell access before this shot for LH setup; gas jet setup.

Gas jet plenum filled to 50 bar with mix of 85% He/ 15% Ar.

Cryopump will not be pre-cooled until just before the shot we want
it on, if any.
May 21 2008 01:59:51:583PM1080521017Robert GranetzShot 17 -- Plasma. LH barely worked, but it still generated hard x-rays. No
synchrotron emission though. Greg reports that the grill is positioned
at 1.5 mm behind its limiter, whereas on the run from 1080320 the grill
was actually 0.5 mm in FRONT of its limiter. But Greg is not willing to
do that in this disruption run.

Next shot: decrease outer gap from 10 mm to 5 mm
May 21 2008 02:28:37:700PM1080521018Robert GranetzShot 18 -- Plasma. Good LH pulse. Hard x-rays obliterate the WIDE2 image, so it's difficult
to see if there's any synchrotron radiation. But there is a brightening in the
LH video view, although not as bright as on 1080320002. Density is staying good and
low (nl_04=0.3e20 m-2).

Next shot: Fire the LPI at t=1.000 s and again at 1.020 s in order to improve chances in case
the injector misfires.
May 21 2008 02:28:21:760PM1080521019Robert GranetzShot 19 -- Plasma. Good LH; lots of hard x-rays. Still no clear evidence of synchrotron
emission. LPI didn't fire for some reason.

Next shot: repeat with LPI
May 21 2008 02:32:47:720PM1080521019Robert GranetzActually, there was a burst of synchrotron emission on WIDE2 at t=0.434 on frame 27 only.
Also, the Z-meter array sees a large asymmetry in bremsstrahlung around t=0.3-0.4 s.
May 21 2008 02:47:36:057PM1080521020Robert GranetzShot 20 -- Plasma. Got LPI, but the first pellet was a fragment, so it was not a clean
sharp disruption time. This one had hints of synchrotron emission on WIDE2.

Next shot: one last try at getting a clean, LPI-triggered disruption.
May 21 2008 02:59:26:253PM1080521021Robert GranetzShot 21 -- Plasma. Got two Li pellets, but still not an instantaneous disruption. The current
quench is still about 2 ms.

Next shot: turn off LPI; program a 100 kA Ip jump at t=1.000 s
May 21 2008 03:16:35:720PM1080521022Robert GranetzShot 22 -- Fizzle

Next shot: in addition to the Ip step, let's also decrease the toroidal field to 5 T

May 21 2008 03:24:42:867PM1080521023Robert GranetzShot 23 -- Fizzle

Next shot:
May 21 2008 03:46:12:337PM1080521024Robert GranetzShot 24 -- Plasma. Got clear synchrotron emission when the LH turns on. The plasma
disrupted at t=1.28 s naturally, but the runaways were gone by then.

Next shot: repeat, but ramp Bt down to 3.0 T at t=1.0 s in order to get a q=2 disruption
at the correct time.
May 21 2008 03:51:07:640PM1080521025Robert GranetzShot 25 -- Fizzle

Next shot:
May 21 2008 04:04:57:023PM1080521026Robert GranetzShot 26 -- Plasma, but disrupted very early (and very quickly) due to an impurity injection.
May 21 2008 04:23:15:647PM1080521028Robert GranetzShot 27 -- Plasma. Another early disruption.

Next shot:
May 21 2008 04:31:50:810PM1080521028Robert GranetzShot 28 -- Plasma. Disrupted at t=0.508 s. There's a curious bump in Ip during the current
quench. There is also a finite signal on the neuts/hards signal during the
quench, but this signal has acausal filtering, so we need to be careful

Next shot: try again for q=2 disruption at t=1.0 s w/LH
May 21 2008 04:47:13:540PM1080521029Robert GranetzShot 29 -- Plasma, but disrupted very early.

Next shot:
May 21 2008 04:55:34:907PM1080521030Robert GranetzShot 30 -- Plasma. Another early disruption.

Next shot: Set Bt constant at 5.0 T; enable gas jet to fire at t=1.000 s for 1.5 ms.
May 21 2008 05:02:46:880PM1080521031Robert GranetzShot 31 -- Plasma. Disrupted at t=0.65 s, well before the gas jet (which did indeed fire).
No synchrotron emission.
