------------------------------------------------------------------------

See the Physop Summary for technical details.

The initial goal of the run was to engineer a discharge with the
following characteristics: Inner wall limited, L-mode, low triangularities
and elongation. The current to be ramped to about 1.3 MA to achieve a final
q_a of 2.6. Further, high density (3 x 10^20 m^-2), small outer gap (0.5 cm)
and 2 MW ICRF from 0.5 to 1.5 s was desired.

After a couple of fizzles and no power shots, we got the first plasma on
shot 4. This was loaded from 1031125033, segment 1 from 1031202029. The
target plasma was 1000620020. From shots 4 to 15 we worked our way towards
the 2000 plasma.

We increased the density and current, decreased the outer gap for shot 5.

The outer gap became too small, so was increased for shot 6. We also continued
to increase the density. Since we changed both density and outer gap, good
ICRF matching was quite difficult. The target outer gap of 0.5 cm was
reached.

For shot 7 we increased the density rise somewhat to arrive at a flat density
level at 0.8 s. The current was raised to 1 MA.

The parameters of shot 8 were similar to those of shot 7.

For shot 9 we put in a current ramp-up, resulting in a final current
of 1.2 MA. This resulted in the first q_a below 4 (3.75 at 1.2 s). We
lowered the density to improve ICRF coupling.

For shot 10 we increased the current ramp further (to 1.3 MA) and
continued to decrease the density slightly. We began to make shaping
modifications (triangularities and elongation) to reduce q_a further.
The trace of q_a was good from 0.5 to 1.4 seconds.

We continued shaping changes for shot 11; the density continued to rise
throughout the shot. The outer gap increased a few mm.

For shot 12 we continued shaping changes. Again an uncontrolled density
increase. It may be because we touch unconditioned parts of the inner
wall.

Shot 13: Same situation as shot 12, early disruption. Both elongation and
triangularities came down quite a bit wrt shot 12. Outer gap now more than
1 cm. Density now flattens again.

Shot 14: Further improvements to the shaping, q_a reached 3.2. Density
behaving strange, overshoots, drops and then rises again. Outer gap 2 cm.

Shot 15: First of two 'model' shots. Density still behaves as for shot 14,
but the current is larger than for shot 14, resulting in a final q_a of
2.9. Outer gap 2.5 cm.

Shot 16 was the first fizzle since shot 3.

Shot 17: Current decreased to 1.2 MA, outer gap 3 cm. Density still not
completely flat but has improved. q_a down to 2.85. Elongation,
triangularities further reduced.

Shot 18 was a fizzle.

In shot 19 we brought the current back up to 1.3 MA and decreased the
outer gap from 3 to 2 cm. Second 'model' shot. Density trace good now,
has become flat again close to the requested value. Lowest q_a of the
day, 2.75 (target 2.6).

Shots 20 and 21 were fizzles.

Shot 22 was a repeat of shot 15. Triangularities were lower and the density
more flat. q_a 2.9 again.

Shots 23-26 were fizzles. We did 10 min ECDC after shot 26.

Shots 27 and 28 were attempts to repeat shot 19. The q_a's reached 2.9
and 2.8, respectively. Density was way high compared to the request,
probably due to ECDC wall effects.

***

Power supply settings meant that we had early disruptions during most of
the day. Bill Rowan thinks this can be mitigated/eliminated by careful
setting of the power supplies for next attempt. We may also have to
decrease the density, but that depends on inner wall conditioning.
We had indications that the conditioning of the innner wall improved
during the run.

Since we came nowhere near completion of the MP, it is necessary to schedule
another run day, preferably before the end of December. If possible,
I would prefer that Bill Rowan is the Physop for this next run as well,
since he has a good idea about how to finalize the discharge type.

The plan would be to finalize step 2 of the Run Plan, and then
move to scans of density, flattop current and power.

***

As far as physics is concerned, shots 15, 17, 19, 27 and 28 will be studied.
We'll be looking for slow changes in turbulence (magnetics, density etc.) and
electron temperature.

Good data was acquired by the profile diagnostics and acceptable data from
PCI and reflectometry.

For some shots, a slow rollover in temperature was observed, but the
observations are complicated by the non-steady ICRF and non-flat density.
For the final shots we attempted to repeat shot 19 so that ICRF could be
better matched, but we did not get back to the conditions of shot 19
before the end of the run.

The peak of the temperature appears to coincide with a decrease of
turbulence measured by the PCI (frequency interval). This observation
is corroborated by the reflectometer.

Physop Summary for Wedesday, December 3, 2003, 1031203

Purpose: MP 367A: Interplay between confinement, turbulence and magnetic

--------------------------------------------------------------------------
Summary-------------------------------------------------------------------
The operational goal of this run was to develop a discharge limited
on the high field side with low elongation (~1.4) and low upper and lower
triangularity (~0.2). The discharge was to have high density and low q with
a q scan accomplished by scanning the plasma current up from 1 MA.

Starting from 1031125033, two acceptable discharges were developed,
1031203015 and 1031203019.

The first shot of the day was a very disappointing fizzle. The startup used
was from 1031125033, a recent shot. It turned out that the calibration/control
for OH1 had changed and this required a new value for the programming of
BZ_0 in segment 1. With that info, the startup from 1031202029 was copied and
the next plasma attempt (1031203003) was a success. There were two
intervening no-power shots (one without its own shot number). One was due
to a data system hang in init. The other was due to a false power supply fault.

The long series of fizzles at the end of the run is difficult to explain except
by analogy. Recall that some upper null runs that we attempted at the end
of the previous campaign were also plagued by fizzles. This was associated with
exposing new surfaces to plasma. A similar thing may have happened here.
Some discharges showed runaway density increases during this run. After a
number of shots, this effect disappeared indicating an evolution of wall
conditions. Wall conditions were therefore affecting this run in unaccustomed
ways and it may be that was the cause of the fizzles. ECDC was used to
end the string of fizzles.

The plasmas were disrupting at the beginning of the rampdown. This may have
caused a fizzle during the next shot, but I am not aware of it causing long
strings of fizzles.

If the discharge is run again, particular attention should be given to avoiding
the disruption. This will require some care in setting power supply limits
and a reduction of either density or current.

Plan

For details see MP 367A on the web. There will be a couple of changes to the
discharge parameters wrt. the MP:
a) Initial ICRF heating will be delayed from 0.3 to 0.5 seconds and
increased from 0.5 to 2.0 MW.
b) We will use shot 1031125033 as the initial target plasma.

1) Engineer a discharge type with the following characteristics:
Inboard limited, L-mode, 2.0 MW on-axis ICRF heating, medium field
(5.4 T), high density (5 x 1020 m^-3), q_a = 3.2.

[3 shots] First shot: Load 1031125033, make minor changes to e.g. the
triangularity and outer gap, study EFIT. Next two shots:
Raise current to arrive at q_a = 3.2. For all 3 shots use 2.0 MW
ICRF from 0.5 to 1.5 s.

2) Make slow current ramp-ups to lower q_a from 3.2 to 2.6:
Monitor turbulence, temperature profiles and stored energy. We
expect a local flattening of T_e; this may be reflected in the
stored energy. We expect the modification to follow a rational
q-surface. Keep density constant by feedback gas puffing.

[5 shots] Three shots to tune current and ICRF ramping, two
identical shots.

3) Scan density to establish optimum confinement transition
(flattening of T_e, turbulence evolution, change in stored
energy).

[8 shots] Go from 4.5 x 1020 m^-3 to 1 x 1020 m^-3 in steps of 0.5 x 1020

[5 shots] From 1.1 to 1.3 MA in steps of 50 kA.

5) ICRF power scan at optimum transition.

[5 shots] From 1 to 3 MW (initial phase) in steps of 0.5 MW.
