| Session Leader Plan Thursday 7/26/07 MP 504
The purpose of this experiment is to try and slow down the L-H transition by operating in the unfavorable drift direction and heating just at the threshold power. A slow evolution of the edge temperature pedestal and a reduction in edge fluctuations prior to the L-H transition have been observed in the past when operating under these conditions. We'll try to reproduce and better diagnose these results. This run will utilize the new edge CXRS diagnostics which is now able to make ion temperature, velocity and density measurements in the edge which can then be used to calculate edge radial electric field profiles. A well boronized machine is requested for this run. Boronization Plan: Boronize with 90%/10% boron bottle for at least 10 hours but limit to 120 psi: tc6 70 to 75 mTorr (if discharge kept out of port) ef4 at 200 A rmin 60 rmax 85 rdwell 80 period 20/120 We will begin in LSN low density plasmas attempting to induce slow transition behaviour in the edge tempertature profiles (TS, ECE CXRS) prior to the actual L-H transition. This will be done at several different density points.

| This run was dedicated to MP504 "slow evolution" or "two phase" evolution H-modes. The objective was to re-create and study, with all available diagnostics, the "two-phase" L-H transition that has previously been observed when operating in the unfavorable drift direction. In these transitions a slow evolution of the edge temperature pedestal culminating in the formation of the edge temp pedestal was observed well before the actual L-H transition, while the edge density showed little evolution until the actual transition. This indicates a separation of energy transport from particle transport.
This time the experiment was performed in reversed field LSN rather than forward field USN, which is a better geometry for the TS diagnostic. We ran at Ip=800KA all day, and densities between nl04=0.4 - 0.9x10^20 m^-2. The run was sucessful in so for as we created these transitions and collected a very complete data set on them at one of our desired plasma targets. However, the goal was to do this at 5 target plasmas (several densities and plasma currents), and we only achieved one of five. The run day began at 8AM, but due to camac trouble was delayed. The RF had trouble coming up in the morning, due to the heavy boronization and much of the beginning portion of the run was dedicated to getting the RF conditioned. Once conditioned the RF performed very well. The interesting portion of the run began around shot 10 when we finally achieved two very brief H-modes, although they were the result of monster-saw teeth crashing rather than RF power. However, later in this discharge the RF was steady for long periods, and the plasma started to look like it wanted to go into H-mode all on it's own at surprisingly low input power <2MW ICRF Shot 11 we reduced the density to nl04=0.4x10^20m^-2. and all though it disrupted, there was an L-H transition just before the disruption. Prior to the transition the H-factor reached 1.3, the edge temperature AND density pedestals began to form and large edge toroidal velocity shear was observed. Starting with shot 13-16 we started getting almost exactly what we wanted; H-modes with edge temperature evolution prior to the transition, little density evolution and a suppresion of edge fluctuations. Althought the RF power was constant the stored energy and the H-factor rose steadily for a good 200ms before the actual L-H transition. The H-factor reached up to 2.5, and the stored energy 120KJ, with 2MW total input power. The temperature pedestals and edge toroidal velocity shear hung around even after the H-mode crashed and the H-factor stayed around 1.4. However, we were getting the H-modes almost too easily and attempted to use slow RF ramps to try to lengthen the "pre-transition" portion of the shot and only get the H-mode at the very end. The RF power ramps were v. successful on shots 17 & 18. We didn't get an H-mode on shot 17, so increased the RF power ramp a little bit and got the slow transition plus an H-mode at the end of shot 18. Prior to the L-H transition on shot 18 temperature pedestals were already formed that were 80% of the H-mode pedestal and toroidal edge velocity gradients existed 60+% of their h-mode values. There was no appreciable rise in the edge density prior to the transition. Stored energy and the H-factor were rising before the transition, but the RF was ramping as well. After shot 18 we decided to move onto nl04=0.9x10^20m^-2. Shot 20 was the only shot at this target where we obtained the "two-phase" transition. After this point we were plauged by disruptions, fizzles and duds, oh my! Cameras showed we were cooking something on the inner wall though it's not clear what, and had lots of UFO's flying around. Also, we lost another flux loop, which officially ended the run. All in all, once the RF was conditioned it ran very cleanly, and we got some very interested results and a very complete data set on at least 1 of the desired target points. |

| The run started out slow with some CAMAC problems that ended up costing us the first hour of the run so that the early start still meant first plasma at 9:00 am. Then, there were some problems charging the EF1 capacitor that cost us a couple of test shots. Once we got going, it took some time for the ICRF to tune up, but eventually, we did get a number of good shots with slow L-H transitions that will be quite useful. See the Session Leader's summary for details. We also added a brief pulse of LHCD at the very beginning of the discharge for several shots to do some piggyback work on MP494a, which were successful as a number of high frequency bursting modes were observed with reversed field. Then, we started getting early disruptions. First, they were blamed on the early LH pulse, but then when that was turned off, the disruptions continued and it appeared that something might be sticking into the plasma from somewhere as there were showers of sparks after the disruptions in the JANT camera view. The WIDE1 camera failed for some reason so that its view was not available. Then, I had some problems with startup and modified Br0 and Bz0 a bit and the startup improved, but the disruptions continued early in the current rise. Finally, there was an offset error on flux loop F19 on shot 28, which got even larger for shot 29, which was a dud. So, we stopped the run to discharge a capacitor on F19 and ran a couple of EF3 test shots to see if the flux loop were repaired. Its signal was still lower than its symmetric loop indicating a short circuit. So, we stopped the run early. Steve Wolfe then began rewriting the analysis software to ignore F19 and make up an equilibrium without it. We expect to run again on Tuesday next week, though it will mean finding a new starting point and all old shots will have to be modified to remove the broken flux loop from the analysis. This is the third flux loop to fail together with F10 and F11, so we are seriously limping in the equilibrium analysis at this point and we will soon have to stop and replace at least the broken flux loops to get good quality equilibrium reconstructions again.
Overall, there were 31 shots with 24 plasmas, 5 tests, 1 fizzle and 1 dud.

| Jul 26 2007 09:07:43:730AM | 1070726002 | Rachael Mcdermott | next shot lower density a little bit, and increase outer gap by 0.5cm to help RF come up |
| Jul 26 2007 09:58:29:710AM | 1070726005 | Rachael Mcdermott | L-mode, LSN, nl04 .7*10^20
next shot repeat, trying for more power |
| Jul 26 2007 10:09:28:443AM | 1070726007 | Rachael Mcdermott | L-mode, LSN
next shot repeat RF coming up slowly, try again |
| Jul 26 2007 10:21:37:723AM | 1070726008 | Rachael Mcdermott | Same shot, longer flat RF pulse, LSN, still no H-mode. RF still coming up
Beam current looks good, CX signal still mediocre at best, don't know why. |
| Jul 26 2007 11:21:26:603AM | 1070726010 | Rachael Mcdermott | Repeat RF getting better
edge temperatures coming up a bit every shot increased DNB arc current to 4.1, test 312 looks good CX data not so good not much on either H-mode |
| Jul 26 2007 11:33:48:837AM | 1070726011 | Rachael Mcdermott | Something funny with DNB store. Tree says gate valve did not open, though it clearly did!
toroidal velocity looks H-mode like by .89s. something funny in the build up just before this, too. |
| Jul 26 2007 11:35:03:090AM | 1070726013 | Rachael Mcdermott | Moved DNB start time back to 0.4s. |
| Jul 26 2007 11:47:53:353AM | 1070726013 | Rachael Mcdermott | Moved DNB start time back to 0.4s.
Exactly what we want! Slow transition. yay! Serious velocity shear before the RF transition |
| Sep 11 2007 06:14:04:180PM | 1070726014 | Rachael Mcdermott | Another great shot, 2-phase transition. Getting into H-mode almost too easily, lower the power down to 1.8-1.9MW, other than that keep everything the same.
There is a tiny impurity injection? at T=.79s that messes up 1 frame of CX data. Frame number 34. |
| Jul 26 2007 12:27:42:820PM | 1070726015 | Rachael Mcdermott | Changing beam timing to 15ms off 30 ms on.
Running NCS cycle between shots, Mass=2 line Argon puff increased to 60 ms LH turning on, in the first 100ms for 300kw. RF reduced to 1.6MW, starting at same time |
| Jul 26 2007 12:28:30:620PM | 1070726016 | Rachael Mcdermott | Next shot Ramp RF from 1Ma to 1.7 MW starting at .7s
Good shot, like the fast beam timing, still enough signal even in L-mode sections H-factor on this up to 2.5s |
| Jul 26 2007 12:35:18:127PM | 1070726017 | Rachael Mcdermott | Good shot, stored energy and H-factor ramping throughout the shot, but no transition. Ramp the RF hirer next shot.
Next shot Ramp RF from 1.2MW to 2.0MW starting at .7s Otherwise same shot. LH still firing in very beginning of shot |
| Jul 26 2007 12:59:15:030PM | 1070726018 | Rachael Mcdermott | Good shot, H-mode at the end of the RF ramp.
Clear temperature pedestal and large toroidal velocity shear before the transition, building throughout the shot Finished this target, move to higher plasma density Next Shot nl04 = 0.9*10^20 Ip=800KA RF ramp from 1.4MW to 2.4MW starting at t=0.7s Everything else the same. |
| Jul 26 2007 01:00:54:313PM | 1070726019 | Rachael Mcdermott | Disrupted. ouch.
Next: Repeat this shot (minus the disruption) Changed DNB timing back to 20off 40ms on. |
| Jul 26 2007 01:21:34:697PM | 1070726020 | Rachael Mcdermott | Nice. Two-phase transition
Transition to H-mode occured at RF=1.8MW, didn't quite get to requetsed density Next shot: Increase requested density to nl04=1.0 to get to 0.9 RF power ramp 0.7s from 1.2MW to 2.0MW |
| Jul 26 2007 01:25:54:763PM | 1070726021 | Rachael Mcdermott | Disruption

up to the disruption. They increase sharply after 0.08 s. Turn off LH for the next shot. |
| Jul 26 2007 01:14:33:983PM | 1070726020 | Joseph Snipes | Shot 20: LH turned off. Density increased at 0.157 s from 3 to 3.5 x 10^19 m^-2
to also try to kill any runaway electrons. Good shot. |

| Jul 26 2007 01:40:47:950PM | 1070726022 | Joseph Snipes | Shot 22: Turned off LH as it seems to have led to the disruption. Try again.
Good shot. |
| Jul 26 2007 01:50:41:463PM | 1070726023 | Joseph Snipes | Shot 23: Fizzle! |
| Jul 26 2007 02:09:19:437PM | 1070726024 | Joseph Snipes | Shot 24: Reduced prepuff by 3 ms to 16 ms duration. Failed current rise after
reaching 130 kA. Bz is a little too negative. |
| Jul 26 2007 02:16:26:837PM | 1070726025 | Joseph Snipes | Shot 25: Increased EF4 current from 1310 to 1325 A. Increased Br0 offset from
0.0025 to 0.003 T. Disrupted at 0.2 s. |
| Jul 26 2007 02:41:08:863PM | 1070726026 | Joseph Snipes | Shot 26: Repeat. Disrupted at 97 ms. It appears to be injections seen in the JANT video camera view. |
| Jul 26 2007 02:43:40:680PM | 1070726027 | Joseph Snipes | Shot 27: Try again. Disrupted at 0.09 s. |
| Jul 26 2007 02:59:43:713PM | 1070726028 | Joseph Snipes | Shot 28: Increased prepuff by 3 ms to 19 ms duration. Raised preprogrammed gas
on PG3 from 0.07 to 0.1 s slightly. Reached 170 kA then died at 35 ms. |
| Jul 26 2007 03:16:43:687PM | 1070726029 | Joseph Snipes | Shot 29: Reloaded shot 22 and increased EF4 current by 15 A to 1325 A and increased Br0 by 0.5 mT to 3 mT and decreased prepuff by 4 ms to 15 ms duration.
Dud! Offset on F19 up to -4.6E-02 on this and shot 28. |
| Jul 26 2007 04:04:42:210PM | 1070726030 | Joseph Snipes | Shot 30: EF3 test shot for F19. F19 was not fixed by zapping it with a capacitor.
So, we seem to have another dead flux loop in addition to F10 and F11. |
| Jul 26 2007 04:26:21:690PM | 1070726031 | Joseph Snipes | Shot 31: Another EF3 test shot for F19. It seems F19 is still not measuring
correctly. So, the run is over until the software can be reconfigured to ignore this flux loop. Perhaps, we will run again on Tuesday. |
