Run plan for MP #408a
Alfven cascade studies in the current ramp with early ICRF and imporved n
number meaurements

ICRF on from 0.050 sec to 0.500 sec


1. Establish clear Alfven activity using 1050427024 (6 shots)
BT~5.4 T, Ip~0.8 MA
D 0.8 MW
E 0.8 MW
J 1.4 MW

2. Investigate parametric dependence on ICRF resonance location,
plasma current and threshold power level. (20 shots)

Scan BT [5,5.2,5.4,5.6,5.8]
Bracket threshold [1 MW, 2 MW, 3 MW] - finer scan once threshold is
bracketed
Ip scan [0.6,1.,1.2] field determined after field scan

3. If necessary/possible for n number measurement, raise power to 5 MW

4. investigate dependence on fast-ion pressure
J on axis 5.2 T, 5.6 T
D and E 5.4 T, 5.8 T

TF invert at 0.6 sec

Attempt to create upper null dischages. This may delay the H-mode
onset, giving a larger fasst-ion population until later in the shot.

Engineering Setup for Tuesday, 3 May 2005

MP 417. Post-boronization evaluation

Session leader: Y. Lin
Physop: R. Parker

Boronize overnight, mainly to outer limiters and antennas,
followed by 2+ hours of ECDC in D2

Run begins at 09:00 and amy extend to 21:00

Power systems as on 1050429001 (fidicial)

Gas setup:
fill B-top with 6 psi D2 Hybrid enabled (PG4)
fill B-side lower with 2 psi Ar Hybrid enabled (PG1)
leave B-side upper as is Hybrid disabled
fill B-main(C-side) with 40 psi D2 Hybrid Enabled (PG3)

fill Ninja with 8 psi N2 Leave disabled to begin

Torvac setup: Machine gate valves closed for first shot, open thereafter

Enable Gate Valves (assuming no vacuum problems) for
ECE, VUV, Z-bolo shutters

ICRF: All transmitters in run on at 8:30


SL Run Plan: After fidicial shot (with gate valves closed) and boronization
recovery:

1. Load shot 1050426022 (including D2 puff in H-mode).
Slightly modified RF waveform. 3 MW from 0.7 to 0.95 sec,
4 MW from 0.95 sec to 1.15 sec, and 5 MW from 1.15 to 1.5 sec.

Do a density scan in the first 3 shots, target density at
nl = 1.1, 0.9, 1.3e20 m^-2. For the subsequent shots, choose
the density that give the best long EDA H-mode

Assess the boronization effectiveness using the first 15 plasmas.

2. Decision point.
A. If the performance is excellent (Wtot >= 170 kJ at 3 MW RF),
we will continue running the same 1 MA plasmas until we see definite
degradation of performance.
(criterion: Wtot <~ 150 kJ at 1 MA and 3 MW Prf.)
the run will stop as soon as there are
three consecutive plasmas meeting the degraded performance
criterion.

In this case, we possibly run until 9 pm. No boronization will be
followed.

B. If the boronization has worn out substantially after 15 plasmas
(150 kJ < Wtot < 165 kJ at 3 MW, 1 MA), we will continue 1 MA shot
until we see three plasmas with Wtot <~ 150 kJ at 3 MW and 1 MA.
If time allows (earlier than 5 pm), we will try boron shaker
to inject boron to the outer limiter.
We will also try Li-pellet injection. And see whether there is
an improvement on the performance.

In this case, the run will probably stop at 5 pm. No boronization
will be followed.

C. If the boronization is shown to be a "bust" (3 consecutive plasmas
at Wtot < 150 kJ at 1 MA, 3 MW Prf),
we will try the boron shaker and Li-pellet injections. We may also
do N2 puff into RF heated L-mode and identify the dominant
Mo sources.

In this case, the run will definitely stop at 5 pm.
Following this run, we will boronize the machine
in a "normal" (to be defined) way.

MP #408a
Alfven cascade studies during the current ramp with early ICRF and imporved n number measurements

The run day started with a number of problems, inlcuding PCI alignment and feedback control
problems, 1 fizzle, 2 duds, and 2 disruptions. Perhaps most troublesome for the day was
annoying, though fortunate, discovery that the magnetics time base for one digitizer was
shifted by about 80ms. Alfven activity was first observed on shot 5, mainly in the form of
TAE's with some sign of small cascade activity. Initial density was higher than the chosen
target density by about a factor of 1.5. It was decided that an attempt would be made to
lower the density to the desired nl_04 level of 0.5. After several unsuccessful attempts
resulting in disruptions at shots 11 and 12, we went back to the conditions from shot 6.
Subsequently we ran at densities of about 0.7-0.8 in nl_04 and were quite usccessful in
obtaining Alfven activity. The intention of the run plan was to establish threshhold values
for ICRF power needed to drive the cascade modes unsable. Scans were conducted at field
values of 4.8, 5.0, 5.4, and 5.8 T. For the 4.8T shots, the results are only partially
conclusive. The ICRf power was not as stable as we would have liked, tripping at about 0.1
sec. Still, this showed that at values of 2.5 and 3.0 MW only the downward chirping mode
was excited. This is in agreement with Joe Snipes' results from last year and Zonca's
predictions for the high field side instability. The power scans at the higher fields had
excellent ICRF stability and repeatability. These scans showed that the threshoold for the
cascade modes was somewhere between 2.0 and 2.5 MW. The 5.8T power scan showed no definite
cascade activity, though many of the cascade/TAE transitions even at the 2.0 MW level. We
were not able to get stable ICRF power at the 3.0 and 3.5 power levels. Overall, the run was
partially successful in establishing alfven activty thresholds and serves as a good compliment
to the studies from April 2004.

The run started off slowly because of computer problems and PCI problems, but by running short shots, we
managed to make up for it to some extent. For inexplicable reasons, there were 3 duds. A 2 ms change in
the prefill and a later 0.4 mT drop in Br0 kept the duds away until the next to last shot. Then, a small
drop in EF4 gave us the final shot. Alfven cascades were observed on a number of shots and a power and TF
scan were performed. Overall, the results were not too bad, but not as clear cut as we would have liked.
The inboard heating at 4.8 T still led to weak downward sweeping modes as before and no upward sweeping
cascades or TAEs. However, at 5.0 T, we could get clear cascades and TAEs.

----------------------------------------------------------------------------
Apr 29 2005 09:23:06:587AM1050429001Joseph SnipesShot 1: Loaded shot 1050428003 for a fiducial. After some delay due to
computer issues, we finally got a good fiducial shot.
Apr 29 2005 09:48:14:853AM1050429002Joseph SnipesShot 2: Loaded shot 1050427024 and chopped off nl04 at 5 x 10^19 m^-2. Set the TF rampdown to begin at 0.6 s
allowing 0.1 s after the ICRF switches off at 0.5 s for the LH to do tests. Physop screwed up and
changed segment 2 when it was segment 4 that was active. So, we got a copy of 1050427024 with RF
in the current rise instead.
Apr 29 2005 10:01:32:697AM1050429003Joseph SnipesShot 3: Now, chopped off nl04 at 5 x 10^19 m^-2 in segment 4 and set the TF rampdown to begin at 0.6 s
allowing 0.1 s after the ICRF switches off at 0.5 s for the LH to do tests. This is an upper single
null discharge to keep the plasma from going into H-mode. Fizzle!
Apr 29 2005 10:13:59:103AM1050429004Joseph SnipesShot 4: Fields looked fine. Lowered prepuff by 2 ms to 18 ms duration. Also changed plasma current to ramp
down at 0.5 s with the TF. Good shot.
Apr 29 2005 10:30:37:383AM1050429005Joseph SnipesShot 5: Changed the plasma current to begin rampdown at 0.6 s for the LH tests. Reduced preprogrammed gas
puff in the current rise to try to lower the density early, but still avoid runaways. Disrupted at
0.72 s due to LH induced impurities. LH switching off for the next shot.
Apr 29 2005 10:45:08:570AM1050429006Joseph SnipesShot 6: Reduced preprogrammed gas puff in segment 4 by another 15% or so to try to bring the early density
down. Good shot. Nice cascades from 0.14 to 0.24 s.
Apr 29 2005 11:31:31:197AM1050429007Joseph SnipesShot 7: Reduced preprogrammed gas puff in segment 4 by another 15% or so to try to bring the early density
down. Dud.
Apr 29 2005 11:31:54:150AM1050429008Joseph SnipesShot 8: Unclear why shot 6 did not go. Try again. Dud again.
Apr 29 2005 11:36:46:260AM1050429009Joseph SnipesShot 9: Raised prepuff by 2 ms to 20 ms duration. Got plasma. Disrupted at 0.52 s. A single frequency
sweeping cascade around 0.16 s from 200 to 400 kHz similar to 960223047 though there are some more
TAEs around 450 kHz as well.
Apr 29 2005 11:55:08:070AM1050429010Joseph SnipesShot 10: Reduced early gas in segment 1 slightly to try to lower the density in the current rise. Once
again disrupted at 0.49 s.
Apr 29 2005 12:13:17:150PM1050429011Joseph SnipesShot 11: Ian points out there is too much Moly radiation. So, I've tried increasing
CLEARIN to divert the plasma just after 0.1 s. This time it disrupted earlier at 0.32 s.


Apr 29 2005 12:22:49:540PM1050429012Joseph SnipesShot 12: Tried increasing CLEARIN to divert earlier. Disrupted again at 0.33 sec. Too much Moly early.

Apr 29 2005 12:25:25:057PM1050429013Joseph SnipesShot 13: Reduced CLEARIN and RCUR to limit against the inner wall and pull the plasma away from the RF antennas
early in the current rise. Hard x rays and disrupted at 0.43 s.
Apr 29 2005 12:47:09:383PM1050429014Joseph SnipesShot 14: Reloaded shot 1050429006. Reduced early gas in segment 1 to attempt to go to lower density than shot 6.
Disrupted at 0.49 s.
Apr 29 2005 01:01:11:633PM1050429015Joseph SnipesShot 15: Reloaded shot 1050429006 again. Corrected mismatch at segment switch in TF current. Raised nl04
slightly in both segment 1 and segment 4 to try to reduce Zeff early. Disrupted at 0.66 s.
Got the cascades back. Good shot.
Apr 29 2005 01:09:44:963PM1050429016Joseph SnipesShot 16: Try RF power scan. Decreased RCUR before 0.1 s in segment 1 and again after 0.1 s in segment 4.
Good shot.
Apr 29 2005 01:26:01:133PM1050429017Joseph SnipesShot 17: Changed TF and Ip rampdowns to start at 0.5 s. Reduced RCUR early to attempt to pull the plasma
away from the RF antenna at 0.1 s. Good shot. Upper null H-mode at 2.5 MW at 0.44 s. Cascades
have returned.
Apr 29 2005 01:35:24:103PM1050429018Joseph SnipesShot 18: Reduced TF current to 138 kA to reach 5.0 T in both segment 1 and segment 4. CAMAC 2 server problem.
Failed in INIT. No power test shot.
Apr 29 2005 01:56:56:963PM1050429019Joseph SnipesShot 19: Try again to get 5 T. Plasma current dives at 0.96 s perhaps due to an impurity injection. Plasma
recovers but is not a very good shot.
Apr 29 2005 02:19:17:570PM1050429020Joseph SnipesShot 20: Try again to get a decent 5 T shot. Better shot. Disrupted at 0.75 s. Nice cascades from 0.06 to
0.14 s.
Apr 29 2005 02:38:09:447PM1050429021Joseph SnipesShot 21: Repeat at 2 MW to check the cascade threshold at 5 T. Good shot. Downward sweeping AE.
Apr 29 2005 02:56:19:197PM1050429022Joseph SnipesShot 22: Moving to 5.8 T. Forgot to change the TF current so this shot was a repeat of shot 21.
Apr 29 2005 03:25:37:120PM1050429023Joseph SnipesShot 23: Now, TF changed to 5.8 T by setting the TF current to 160 kA. Good shot. Tops of the cascades are
clearly visible.
Apr 29 2005 03:26:28:493PM1050429024Joseph SnipesShot 24: TF at 5.8 T at higher RF power but with faults. Good shot. More cascades are visible.
Apr 29 2005 03:48:36:480PM1050429025Joseph SnipesShot 25: Repeat to try to get a cleaner RF waveform. RF still faulted but otherwise it is a good shot.
Apr 29 2005 03:56:23:103PM1050429026Joseph SnipesShot 26: Try to get a clean 2.5 MW of RF. Good clean 2.5 MW data. Weak cascades.
Apr 29 2005 04:21:02:563PM1050429027Joseph SnipesShot 27: Go to 3.5 MW at 5.8 T. RF reached 3.5 MW but tripped early. Got some brief cascades.
Apr 29 2005 04:22:29:550PM1050429028Joseph SnipesShot 28: Go to 3 MW at 5.8 T. RF reached 3 MW but tripped early. Got some brief cascades.
Apr 29 2005 04:44:41:110PM1050429029Joseph SnipesShot 29: Go to 4.8 T. Disrupted at 0.31 s. One downward sweeping mode from 350 to 250 kHz from 0.165
to 0.185 s.
Apr 29 2005 04:48:01:500PM1050429030Joseph SnipesShot 30: More power Scottie! Dud!
Apr 29 2005 05:14:36:033PM1050429031Joseph SnipesShot 31: It seems the vertical field changed by 2 mT from earlier in the day. So, I lowered EF4 by 25 A
to -1385 A. Good shot again with a couple of weak downward sweeping modes and no cascades or TAEs.
