Run Plan
mp 233a Density limits
(H-mode task force)

Session Leader - Greenwald
Phys Op - Irby mostly

============================

Plan:

(run continues from 1000606)

1. scaling of pedestals/edge parameters near the density limit - in
particular we will be varying Bt and Prf to try to get a wide range
in beta. (The Rogers and Drake simulations have a significant
dependence on the mhd alpha parameter.)

2. fluctuations near the density limit (both H/L and disruptive).

The run follows the general approach of 980115 where we ran high
density H-modes then ramped the current down to the density limit.
The RF needs to be on steadily to the end of the shot.

The plan is to start at 5.3T then move to 4.5T and finally to 6.0.
The 6T shots will be ohmic and we will be looking at the disruptive
limit only

The outer gap should be in the range 1-1.5 cm so that we can get
good data from the Lyman alpha array.

=======================================================

Results:

Problems - but interesting results were obtained.

The bad news: The first part of the run was plagued with
impurity injections coming of the E port antenna. These
were clearly visible with the fast camera and resulted in
impurity buildup and very high radiated power. The H-modes
were lost early. We decided to lower the RF power and
proceed in L-mode. At this point faults with the OH system
shut us down for about 4 hours.

The good news: When we returned we got 4 shots all L-mode the last
3 with ohmic alone. All 4 disrupted right at the empirical limit.
We got good probe data on 016-018. Plunges were taken at 0.6, 0.85
and 1.1 seconds - these correspond to 0.37, 0.5, 1.0 times the
limit. A quick look showed that there was a substantial increase in
the potential and density fluctuations for the finaal scan. The
fluctuation character also seemed to change: the ISat fluctuations
were dominated by lower frequency features. These observations
generally support the notion of the density limit as a transport
collapse (as compared to a radiative collapse). Unfortunately the
probe was damaged during an earlier run so we can't get the
ExB convected flux. We do seem to have good Lyman alpha data.

Aside from doing detailed analysis on these shots we still need to:

1. do similar experiments with limited plasmas - the limit is
observed to be robust with respect to topology

2. vary the probe times during the last few hundred msec. We want
to know if the change in fluctuations/transport occurs gradually or
catastrophically.

3. run shots at different toroidal field - try to vary beta to
compare to Rogers Drake theory.

The following gate valves should be enabled: ECE, VUV, DNB

RF will be required as during the 1000606 run.

This run is in support of MP233A --- Density Limits


Results:

We started the run where it left off on 6/6 with shot
1000606014. This shot indicated a successful density limit
disruption, and the first shot from today was right on Martin's
curve. Shot 3 only lasted about 0.8 s. Not sure why, but
decided to blame Brian's probe. I didn't notice until it was
too late that the gas pressure was rising at startup, resulting
in a fizzle on shot 4. Dropping the prepuff on shot 5 by 2
ms did not fix the problem. Another 2 ms got a plasma back on
shot 6.

It looked like the e-port antenna was arcing and possibly doing
in the plasma. Two arcs appear on the face of the antenna
near top. It seemed pretty clear that they were emitting material
into the plasma during the shot. The e-port side tiles are also
getting pretty hot at the midplane. We tried various tweaks
to reduce the arcs such as dropping zcur and reducing rcur,
but we still had the problem. Martin finally asked that e-port
be turned off. After shot 15 we also turned off d-port. Shots
16 and 17 were good shots for the ASP.


Engineering Problems:

We had duds on shots 11 and 12 caused by an OH2L crowbar.
This problem cost us about 2 hours of run time. Three
blown fuses were found after shot 12. The SCRs, gates,
and timing checked out okay. Two OH2L test shots were
taken at 5 and 10 kA, followed by a successful plasma
shot.


Score:

plasma 11
fizzles 2
duds 2
tests 2

Shot 09 -- Plasma. Disrupted at t=1.03 s when Ip=0.67 MA, close to
expected density limit. Leading points on top of D-port
antenna are still glowing.

Next shot: reduce outer gap by 2 mm (i.e. RCUR by 1 mm),
tweak Br0, and reduce IC_EF4 by 500 amps during most
of segment 2. The IC_EF4 change was suggested by Steve Wolfe,
with the idea being that EF3 will then contribute more of the
vertical field, and it's more curved than EF4's field lines.

Session Leader Comments
Jun 9 2000 08:50:38:717AMMartin GreenwaldEarlier work[1] has suggested that the tokamak density limit can
be explained fully only by consideration of transport effects. While
there is little dispute about the final stages of a density limit
collapse - edge cooling via radiation then shrinkage of the current
channel leading to MHD instability and disruption - theories based
on edge power balance physics alone can not explain important aspects
of density limit phenomenology. In particular, the power balance
theories predict a density limit with strong dependence on input power
and on impurity content. Neither of these dependences are generally
observed. These classes of theories also have difficulty explaining the
robustness of the density limit with respect to plasma configuration,
divertor topology, or operational regime. Finally there is data from
Alcator C, TEXT, and MTX (nee Alcator C) which show degradation of
particle confinement or enhanced fluctuations in the vicinity of the
limit.

The work by Drake and Rogers suggest a specific turbulence mechanism
for this phenomenon. The simulations show a boundary, above which
fluctuations increase dramatically from nominal ``L'' mode levels.
This boundary has somewhat complex parametric dependence but has
much in common with the empirical limit derived in reference [1]. The
edge pressure gradient is an important parameterization for the
computationally derived boundary - thus we propose a power scan as
part of this mp. We note in passing, the rough agreement with the
L/H threshold of simulations carried out with the same code [4].

Recent studies by LaBombard [2] have suggested that the edge
diffusivity increases strongly with local collisionality. Since the
edge temperature is roughly fixed by parallel transport, this
correlation is consistent with an increase in transport as the
density is increased.

A number of machines have reported a degradation in H-mode confinement
as the density limit is approached. This effect apparently sets in at
lower densities for P $\sim$ P$_{THRESHOLD}$. So far, C-Mod H-modes have
been in this regime. With additional RF power we should be able to
access the regime with P $>>$ P$_{THRESHOLD}$.

Jun 9 2000 08:52:02:810AMMartin GreenwaldPlan:

1. scaling of pedestals/edge parameters near the density limit - in
particular we will be varying Bt and Prf to try to get a wide range
in beta. (The Rogers and Drake simulations have a significant
dependence on the mhd alpha parameter.)

2. fluctuations near the density limit (both H/L and disruptive).

The run follows the general approach of 980115 where we ran high
density H-modes then ramped the current down to the density limit.
The RF needs to be on steadily to the end of the shot.

The plan is to start at 5.3T then move to 4.5T and finally to 6.0.
The 6T shots will be ohmic and we will be looking at the disruptive
limit only

The outer gap should be in the range 1-1.5 cm so that we can get
good data from the Lyman alpha array.

of segment 2. The IC_EF4 change was suggested by Steve Wolfe,
with the idea being that EF3 will then contribute more of the
vertical field, and it's more curved than EF4's field lines.
Jun 9 2000 12:43:19:887PM1000609010Robert GranetzShot 10 -- Plasma. Disrupted at t=1.06 s when Ip=0.64 MA, before reaching
the expected density limit. Still lots of interaction with the
E-port antenna. The RCUR and ZCUR changes made over the
last two shots definitely show up in the EFIT reconstructions.

Next shot: repeat with D-port antenna only.


Jun 9 2000 12:57:05:357PM1000609011Robert GranetzShot 11 -- Dud. OH2L crowbarred around t = -0.2 s.

Next shot: try again, with RF from D-port only.

Jun 9 2000 01:48:34:077PM1000609012Jim IrbyNo e-port RF for this shot --- eliminate injections?

Dud ---- OH2L Crowbar again --- crew to cell
Jun 9 2000 04:06:11:903PM1000609013Jim IrbyAfter about 2 hours of tests in the power room we found
3 bad fuses, but no problems with gate boards or other
OH2L components. No bad SCRs.

This will be a low current OH test

All okay.

Jun 9 2000 05:15:07:047PM1000609017Jim IrbyIncreased RCUR by 2mm late in time to move out
a little toward the ASP.

Plasma moved out nicely to meet the probe.
