MP#479 ""Effect of magnetic shear on edge gradients""

Goal
These experiments will investigate the role that magnetic shear may play
in setting the observed pressure gradients near the last-closed flux surface (LCFS)
in ohmic-heated L-mode discharges.

Approach
Vary the magnetic shear at the LCFS by fixing the magnetic topology but varying
the flux surface that defines the LCFS. This is done by first dialing up a double-null
plasma and then systematically reducing the inner wall gap such that the discharge
goes from diverted to inner-wall limited.

Plan
Load from shot#1070511029. This shot ran on segment#4. It was a near-DN discharge
with SSEP control: Ip=0.8 MA, Bt= 5.4 tesla, NL04 = 1.1e20.
Reprogram NL04=0.8e20 and set SSEP to 0.0

ASP, FSP, WASP (for diverted plasmas only) programmed to scan at 0.7, 0.9, 1.1 seconds
GPI viewing lower x-point region.
Edge Thomson scattering with optimized SOL channels.

Shots
Reload #1070511029, turn on segment#4, set SSEP=0.0, NL04=0.8e20

Shots 1-4: Adjust inner gap to 12 mm, outer gap to 15 mm. Optimize scanning probe targets.
Use WASP probe to see if DN balance is attained.

Shots 5-12: NL04 ~ 0.8e20 m-2, scan inner gap: 5, 2, 0, -2, -5, -10 mm
Keep outer gap the same.

Shots 13-20: set NL04 ~ 0.4e20 m-2, can inner gap: 5, 2, 0, -2, -5, -10 mm
Keep outer gap the same.

Shots 21-28: set NL04 ~ 1.2e20 m-2, scan inner gap: 5, 2, 0, -2, -5, -10 mm
Keep outer gap the same.

Run Summary for 1070518

MP#479 ""Effect of magnetic shear on edge gradients""

This was a very productive run. We ran double-null plasmas all day with varying 'clearin' distances,
causing the discharges to be either diverted with a finite inner wall gap or to be limited onto the
inner wall. In limited discharges, the spacing between the last-closed flux surface and the separatrix
was varied systematically to a maximum of about 12 mm.

We got about 12 shots with a fine clearin scan (~2mm steps) at a nominal density of NL04~0.85 and
with the ASP and FSP probe systems plunging sufficiently deep. The WASP probe was also used to
investigate high-field side profiles in regular double-null plasmas as well as some inner-wall
limited plasmas. (Yes we found that the WASP probe can be used in inner-limited plasmas. We just
don't scan it very far!) The new tungsten electrode geometry, which is now on all the scanning
probes, worked extremely well, surviving some over-insertion errors (Te = 100 eV!) without showing
any damage.

After shot#18, we tried to lower the density to begin the low-density (NL04~0.4) clearin scan part
of the MP. However, these innner-wall limited discharges initially refused to run with densities below
about NL04 ~ 0.6, a phenomenon that we saw earlier during Stewart Zweben's run (MP#428). After
a delay from an OH2U supply problem (shot#22), we did manage to do a coarse clearin scan
at NL04 ~ 0.5. We did not have time to start a high density scan (the MP called for NL04 ~ 1.2).

Before the run, Jerry optimized the placement of the edge Thomson views. He reported that the
ETS system worked well today. His initial analysis of the Thomson data showed that the steep gradient
region essentially followed the location of the LCFS, ignoring the location of the separatrix.
Scanning probe data seems to support this initial conclusion. There may be some differences
in the electron pressure gradient at the LCFS, depending on whether it is limited or
diverted. The Thomson data does not have the spatial resolution to explore this detail.
Therefore, we will need to populate the edge database with probe-profile data to take a close
look at this question. We can't do this immediately because the software needs to be rewritten
to handle the new probe geometries (perpendicular Mach probe) that we are now using.
Stay tuned.

Run was devoted to MP#479 "Effect of magnetic shear on edge gradients" with B. LaBombard as Session Leader. Brian required a systematic scan of the inner gap at two densities for this run. We scanned Clearin from +3mm to -23 mm (strongly inner wall limited) at nl_04 ~ 8.0e19 m-2, then back out to -6 mm with nl_04 ~ 6e19 m-2 (not as low as Brian wanted, but it was what the machine gave us.) The outward scan was courser than the inward one.

Late in the run, Steve reported that an EF power supply was railed for most if not all the shots, and it is interesting that the shots nevertheless went off fairly well.

There were more fizzles and disruptions than one would have liked, some of which were at least partially due to the beam firing without plasma. Brian believes that this results in loosely bound material on the inner wall, where the beam strikes it, and this material is easily knocked off particularly by inner wall limited plasmas.

There was also one machine failure due to a loose connection in the power supply circuitry. This was easily fixed and did not result in a serious delay.

Scorecard: 30 plasma attempts, 23 full length (at least well into rampdown), 3 fizzles (2 after disruptions), 3 disruptions and 1 commutation failure.

May 18 2007 09:32:30:123AM1070518001Ron ParkerShot 1 ran well, probably will be the best of the day.
May 18 2007 09:34:53:530AM1070518002Ron ParkerShot 2 ran OK. More or less the same as shot 1.
May 18 2007 09:39:10:377AM1070518003Ron ParkerShot 3 fizzled. Early breakdown but burnout is slow.

No changes for next shot, see if it goes.
May 18 2007 09:57:09:117AM1070518004Ron ParkerShot 4 disrupted early, 0.18 s. Too much gas.

May 18 2007 10:59:25:437AM1070518008Ron ParkerShot 8 looked good. Next: Reduce clearin by 3 mm, Rcur by 1.5.
May 18 2007 11:14:20:663AM1070518009Ron ParkerShot 9 ran. Next: Reduce clearin by 2 mm, Rcur by 1.
May 18 2007 11:25:51:980AM1070518010Ron ParkerShot 10 ran OK. Next: Clearin reduced by 2mm, from -11 to -13 mm and Rcur by 1 mm from 652 to 651 mm.

May 18 2007 11:55:22:213AM1070518012Ron ParkerShot 12 ran well. Reduce Clearin again by 2 mm, from -13 mm to -15 mm and Rcur by 1, from 651 to 650.
May 18 2007 12:08:39:560PM1070518013Ron ParkerShot 13 ran OK, disrupting on current rampdown around 200 kA. Repeat for next shot.
May 18 2007 12:25:03:880PM1070518014Ron ParkerShots are rolling along. Next: Reduce Clearin by 2 more mm, from -15 to -17 mm, and Rcur by 1,from 650 to 649 mm.
May 18 2007 12:41:12:697PM1070518015Ron ParkerShot 15 looked good. Next: Brian is relentless - reduce Clearin by 2 more mm for next shot.

Reduce Clearin by 2mm, from -17 to -19 mm, but this time leave Rcur at 649 (since the outer gap seems to be growing).
May 18 2007 12:54:24:517PM1070518016Ron ParkerShot 16 ran well. Next: Continue Clearin scan inward. Reduce Clearin from -19 to -21, no change for Rcur.


May 18 2007 01:25:00:057PM1070518017Ron ParkerShot 17 was OK, although startup was a bit dicey.

For shot 18, reduce Clearin by 2 more mm, from -21 to -23 mm. Again, no change for Rcur
May 18 2007 01:25:34:403PM1070518018Ron ParkerShot 18 ran well, startup better than shot 17, but no change was made.

Next: same gaps, nl_04 reduced to 4e19.
May 18 2007 01:34:01:530PM1070518019Ron Parker019. Plasma. Shot was OK
May 18 2007 01:47:10:287PM1070518020Ron Parker020. Plasma. The goal is nl_04=0.4e+20. nl_04 is actually 0.7e+20
May 18 2007 02:00:17:040PM1070518021Ron Parker021. Plasma. nl_04=0.7e+20
May 18 2007 02:20:33:800PM1070518021Ron ParkerNext shot: Returning to approximately the setup of shot 016. The only change is that CLEARIN is changed to -0.019 for this shot.

After shot 021, there was a "bang". The concensus was that this came from the power room. An inspection revealed nothing.
May 18 2007 02:23:00:220PM1070518022Ron Parker022. Power supply problems. OH2U
May 18 2007 02:39:29:070PM1070518022Ron Parker022. Power supply problems. OH2U

Problem has been diagnosed and traced to a broken connection in the commutation network.

Short delay while problem is fixed.
May 18 2007 03:43:03:173PM1070518023Ron ParkerShot 23 was ugly -- started up but disrupted just after 1 s.

Steve reports that EF power supply is railing during the shot --but it ran all day like this?!

May 18 2007 03:47:47:487PM1070518024Ron ParkerShot 24 fizzled, not surprising after disruption on 23.

Beam is giving some problems due to firing without plasma. Beam valve disabled in order to try to finish run plan.
May 18 2007 04:09:26:747PM1070518025Ron ParkerShot 25 disrupted at ~ 700 ms.
May 18 2007 04:29:14:363PM1070518026Ron ParkerShot 26 ran well, Brian's probes were not set properly for this shot and we'll repeat.
May 18 2007 04:30:49:740PM1070518027Ron ParkerShot 27 ran, we'll move the Clearin out to -19, similar to shot 16 but with lower density.
May 18 2007 04:56:09:077PM1070518028Ron ParkerDecent shot, a bit bumpy current rise but usable. Probes weren't deep enough so we'll repeat.
May 18 2007 04:53:56:967PM1070518029Ron ParkerShot 29 ran OK, not a pretty startup but flattop OK. Next and final shot: Repeat of shot 8 with lower density.


May 18 2007 05:10:29:847PM1070518030Ron ParkerShot 30 was OK, disrupted on ramp down @ ~ 500 kA.
