[1, 1.5] sec J: 2.2 MW, [0.6, 1.5] sec result: plasma many H-modes E: 1.2 MW one faults J: 2.5 MW 2 faults Summary: The J-port antenna conditioned to record maximum voltage (~35 kV) with solid heating and negligible impurity or density generation. In the past, J-port has coupled 3.0 MW for ~25 msec (1010727028) with maximum voltage of 24 kV. Previous peak maximum voltage was 30 kV. This is the first time the J-port antenna has operated into plasma at voltages similar to those obtained during vacuum conditioning (~36 kV). The antenna needs further conditioning to operate reliably at higher power and voltages. The plasmas began as inner wall limited until J-port reached ~2.5 MW and then we switched plasma operation to lower single null discharges. These plasmas were typically characterized by multiple Elm-free H-modes surviving ~200 msec. As a result of the Elm-free H-modes, the loading was fairly light but both E and J conditioned and operated fairly well into H-mode. |

| Engineering Setup for WEDNESDAY, AUGUST 14, 2002 Continuation of RF Conditioning SL: Wukitch PO: Parker ECDC from AS SOON AS AVAILABLE UNTIL 07:00 Run Begins at 09:00 (if possible) and ends at 17:00 Power systems setup the same as for Shot 1020813007 Gas setup: B-Top 6 psi D2 Hybrid Enabled (PG4) B-side lower 1 psi Ar Hybrid Enabled (PG1) B-side upper 10 psi D2 Hybrid DISABLED (PG2, for ECDC) C-Side 30 psi D2 Hybrid Enabled (PG3) J-Bottom leave as is, Hybrid DISABLED Enable the following gate valves, assuming no vacuum problems: ECE, VUV, DNB RF Setup: Transmitters 2,3,4 in Run On by 07:00 RUN PLAN: Continued RF Conditioning RUN SUMMARY The run began late due to leftover problems from the power outage the day before, as well as continued maintenance on the OH2 Capacitor bank. This necessitated a number of test shots at the beginning of the run, and shot 6 was the first plasma shot. Shots 6-14 were limiter shots used to condition the J-port antenna. This proved successful, with J-port power reaching about 2.5 MW, although intermittent. Transmitter 1 was not operational and transmitter 2 was operated during the day at a power level of ~ 1 MW. Beginning with shot 15, the plasmas were diverted and RF conditioning continued. Again, the conditioning seemed successful, with the J-port power reaching about 2.5 MW, although intermittent as in the case of the limiter discharges. The plasma followed the bursts of RF power with intermittent entry into H-mode. These conditioning shots continued through shot 30, the last shot of the run. All in all, a pretty good day with 30 shots, of which 7 were tests (with one due to operator error), one disruption, one fizzle and 21 useful conditioning shots. The improvement in cooling (machine, cell, but also the control room -- T=98 today, a record!) is very noticeable and welcome! |

| Aug 14 2002 09:38:52:970AM | 1020814001 | Ron Parker | First shot delayed due to maintenance of OH2 commutation circuit, which had failed on the last shot on 13 August. TF crowbar circuit was also checked to ensure that it will fire in the event of a global power failure, as also happened on 13 August (Weather is very hot and humid!) First few "shots" will test the OH2 commutation bank. First test shot revealed a residual problem with data system. |
| Aug 14 2002 10:23:01:210AM | 1020814002 | Ron Parker | Test shot 2 ran successfully - data system problem was fixed. There will be 2 more bank voltage test shots as the voltage on the commutation bank is brought to nominal value. |
| Aug 14 2002 10:23:50:363AM | 1020814003 | Ron Parker | The third test shot was normal. One more test shot on bank voltage, then commutation test shot. |
| Aug 14 2002 10:24:20:663AM | 1020814004 | Ron Parker | Shot 4, the last OH2 commutation bank test shot, was OK. Next shot, will be a full commutation test. |
| Aug 14 2002 10:26:20:963AM | 1020814005 | Ron Parker | Shot 5, a full commutation test shot, ran OK. Finally ready for plasma on shot 6, after which there will be a cell entry. |
| Aug 14 2002 11:15:04:223AM | 1020814006 | Ron Parker | Shot 6, the first plasma shot, ran as programmed with RF power maximum of 2.5 MW. Antennas D and J are energized today. |
| Aug 14 2002 11:16:23:743AM | 1020814007 | Ron Parker | Shot 7 also ran well, with max RF power reaching 3 MW intermitently |
| Aug 14 2002 11:18:45:497AM | 1020814008 | Ron Parker | Shot 8 ran well, maximum power reaching 3 MW sustained for ~ 300 ms. |
| Aug 14 2002 11:46:44:757AM | 1020814009 | Ron Parker | Short delay (~20 min) while a tie wrap is secured in the OH2 cap bank. Bank didn't charge, shot went without power. |
| Aug 14 2002 12:28:17:853PM | 1020814010 | Ron Parker | After delay, shot 10 ran well, J-port cut out after being intermittent |
| Aug 14 2002 12:14:49:270PM | 1020814011 | Ron Parker | Shot 11 ran OK. Some hard x-rays early in these discharges. |
| Aug 14 2002 12:26:00:303PM | 1020814012 | Ron Parker | Shot 12 ran as programmed. J-port power is still somewhat intermittent, with peak power ~ 2 MW. |
| Aug 14 2002 12:39:29:260PM | 1020814013 | Ron Parker | Shot 13 ran well, net RF power about 3.45 MW. |
| Aug 14 2002 01:18:02:710PM | 1020814014 | Ron Parker | Shot 14 ran OK |
| Aug 14 2002 01:14:41:597PM | 1020814015 | Ron Parker | Shot 15 was diverted (all previous shots were limited). Field was set at 5.4 T -- operator error. |
| Aug 14 2002 01:21:15:683PM | 1020814016 | Ron Parker | Shot 16 ran OK, still diverted. Field = 4.6 T. |
| Aug 14 2002 02:17:20:443PM | 1020814017 | Ron Parker | Shot 17 ran well, about 3 MW of RF. |
| Aug 14 2002 02:15:16:750PM | 1020814018 | Ron Parker | Shot 18 ran, intermittent H-Mode. PF and then TF breakers pulled. Indication: low line phase voltage. It appears that the exciter voltage program pulled the exciter voltage negative too soon. Indications are that the excitor waveform amy have triggered too early. Next shot will be an alternator test. |
| Aug 14 2002 02:40:37:993PM | 1020814019 | Ron Parker | Alternator test -- normal |
| Aug 14 2002 02:41:00:277PM | 1020814020 | Ron Parker | Shot 20 went off as programmed. |
| Aug 14 2002 03:14:17:327PM | 1020814021 | Ron Parker | Shot 21 was a fizzle, first one of the day, CII level was a bit high during burnout. No change for next shot. |
| Aug 14 2002 03:13:28:513PM | 1020814022 | Ron Parker | Shot 22 ran as programmed, about 3.5 MW injected, but still intermittent. |
| Aug 14 2002 04:41:54:540PM | 1020814023 | Ron Parker | Shot 23 ran as programmed. |
| Aug 14 2002 03:36:21:860PM | 1020814024 | Ron Parker | Shot 24 ran as programmed. |
| Aug 14 2002 04:01:02:617PM | 1020814025 | Ron Parker | Shot 25 ran as programmed. |
| Aug 14 2002 03:59:52:943PM | 1020814026 | Ron Parker | Shot 26 ran as programmed. |
| Aug 14 2002 04:40:58:007PM | 1020814027 | Ron Parker | Shot 27 started up, but disrupted at 0.4 s. |
| Aug 14 2002 04:38:32:863PM | 1020814028 | Ron Parker | Shot 28 ran as programmed, again with about 2.5 MW of power from J-port, but again intermittent, and repeated entries in and out of H-Mode. |
| Aug 14 2002 04:48:22:160PM | 1020814029 | Ron Parker | Shot 29 ran off OK. |
| Aug 14 2002 05:08:12:063PM | 1020814030 | Ron Parker | Shot 30 ran as programmed. |
