****980206****980206****980206****980206****980206****980206****980206 MP150A D(He3) Heating at 8T Beginning MP150A (He3 Minority Heating at 8T) today with the explicit purpose of investigating RF absorption. However, we will probably spend considerable amount of time developing the discharge because this is the first 8T run of the campaign. We will begin with 5.4T discharges and creep up on 8T. When raising the TF, ~7.1 T should be avoided because of H cyclotron resonance in the plasma edge could cause damage to the antenna. ------------------------------------------------------------------------------ Engineering setup for 980206: Two hours of ECDC in deuterium before the run, if possible. Engineering setup as on 980204001, with TF under hybrid control Gas setup - fill K-side with 20 PSI of D2, hybrid enable fill B-top with 6 PSI of D2, hybrid enable fill B-side-lower with 3 PSI of Ar, hybrid enable fill B-side-upper with 20 PSI of He3, hybrid enable If this plenum already contains Helium-3 in the range of 15-20 psi, no need to top off. AFTER FILLING THE PLENUM, DISCONNECT THE PLC FROM THE VALVE!!! The following gate valves should be enabled, assuming no vacuum problems: ECE (no others until we verify the status of each system) ST1 PS1 ST2 PS2 1. Start with 5.4T discharges and step up with constant q to investigate off-axis D(H) heating 5.4T, 0.8 MA, nl_04~1.0, q95~4.5 5.7T, 6.2T, 6.6T, 6.9T, 7.3T, 7.6T, 7.9T, 2. 7.9T scan [He3] from low to higher with RF power modulation. 5 msec, 7.5 msec, 10 msec, 15 msec, 20 msec, 35 msec, 50 msec, 75 msec ----------------------------------------------------------------------- Summary: After an initial excitor fault and vibration scare, the run day was fairly smooth except for two computer/CAMAC/PLC failures. The cooling time between discharges was about 20 minutes and we managed to accomplish most of the run plan. In the process of raising the toroidal field up to ~8T shot-to-shot, H-modes were obtained for D(H) minority heating with the H cyclotron resonance as far as 16.7 cm off-axis. H-factor (calculated assuming 90% absorbed RF power injected) was progressively worse. This result differs from JET's experience and reconfirms Yuichi's earlier results. Furthermore, the inverse sawteeth phenomena observed on the inner wall b-dot probes vanished approximately when the H cyclotron resonance passed beyond the ST inversion radius. (003-005 show the progression) The speculation is that the ST redistibutes the minority ions which decreases the absorption. This needs to be investigated more carefully. Another result is the bursting neutron phenomena often observed after a H->L transition. An example of H->L transition accompanied by a corresponding neutron increase is 980206006. The H and 2nd harmonic D resonance is well outside the inversion radius -- 2nd harmonic D absorption cannot be the cause of the increased neutron rate. For fields above 7.1 T (H cyclotron resonance is approximately at the antenna position), He3 was added to systematically investigate the minority and mode conversion regimes. H-modes were not obtained, but the physics results are encouraging. At low concentrations of He3, the bulk ion temperature increases by ~1.2 keV while the electron temperature increases by ~0.7 keV (980206016). In shots 980206020, -022, and -023, the He3 concentration was larger and significant mode conversion was observed. Discharge 980206023 is particularly interesting because the He3 concentration is initially low during the RF and ramps to higher values. As the He3 concentration increases, the RF goes from predominantly minority to mode conversion (ion heater to electron heater). Further analysis is required.

| Physics operator summary for 980206 EO: Bertolino/Fairfax PO: Goetz SL: Wukitch Run 980206 was in support of Mini-Proposal #150A - Helium-3 Minority Heating at 8T. The goals for today are to try and run 8T plasmas and optimize the helium-3 minority heating scanario. The goals were reached today. Plasmas were produced at fields ranging from 5.3 to 7.9T. RF physics was done during the slow march to 7.9T and once 7.9T, 1.2MA was reached. See the Session Leader's report for a discussion of these physics results. Good day for start-up. All plasma attempts were plasmas. Breakdowns were robust even though Br and Bz were bouncing around. Many shots had hesitations on the current rise. The Br offset was chased around from .006 to .0067 and ICEF4 was increased by 25A by the time full field and current were reached. This seemed to cure the hesitation. Hard x-rays were the order of the first half of the day. Increasing the pre-puff duration to 19msec and moving the first PG3 point in segment 1 to .020sec (was .025) succeeded in beating down the hard x-rays. The toroidal field and plasma current were stepped up slowly, keeping q95 constant. This was done to debug the cooling and engineering systems and to do some heating physics on the way. TF waveform was under PLC control today. There is a -3kA difference in the actual current versus the requested current. With the higher voltage available from the alternator, 7.9T flattop was reached by 0.45sec. The start time for this waveform was -1.5sec and the invert time was 1.2sec. This required a cooling cycle of 19-20 minutes. Engineering, computing, and diagnostics today: Two shots each were lost to computer and engineering troubles. A hang of ZENITH and a double highway crash accounted for the loss of shots 010 and 017. An exciter trip and a bearing vibration in the alternator lost shots 001 and 012. The exciter trip was a wrong setting and the bearing vibration was a tickling of the warning limit. The YAG lost a few shots due to CAMAC init errors. Scorecard: 23 shots = 19 plasmas + 0 fizzles + 4 eng. duds + 0 tests Shot summary for Run 980206: Load 980204001 coldstart hybrid - all matrices respond TF under PLC control - start with 156kA limit Shot change result ____ _____ ______ 1 see above exciter and DC breaker trip in the alternator caused weirdness 2 no changes plasma - Ohmic fiducial - hards - nice startup 3 more early gas plasma - RF fiducial - Bt=5.5; Ip=0.84 q95=4.7 4 TF PLC = 162kA; IP=-835000 plasma - Bt=5.7; Ip=.87; q95=4.7 slight hesitation in current rise vacuum fields are low 5 TF PLC = 176kA & start @ -1.3 plasma - Bt=6.2; Ip=.95; q95=4.7 IP=-915000; Br0 = .0065 and very slight hesitation in current rise ICEF4=-1340 6 TF PLC = 187kA; IP=-966000; plasma - Bt=6.6; Ip=1.0; q95=4.7 Br0=.0067; ICEF4=-1335 hesitation in current and a bounce 7 Br0=.0062; ICEF4=-1330 plasma - Bt=6.6; Ip=1.0; q95=4.7 bad hesitation; breakdown @ 6.54T 8 Br0=.0065; TF PLC = 195kA & plasma - Bt=6.9; Ip=1.0; q95=4.7 start @ -1.5; IP=-975000 good current rise & breakdown 9 TF PLC = 206kA; IP=-1100000; plasma - Bt=7.2; Ip=1.1; q95=4.4 ICEF4 = -1325; pulse and 20V slight hesitation; Br o.k.; good maintenance pulse on PG2 breakdown @ 7.2T 10 no power shot to reSYNC PLCs due to ZENITH reboot 11 TF PLC = 215kA; IP=-1130000; plasma - Bt=7.6; Ip=1.16; q95=4.45 PG4=16ms; 25V maintenance good current rise; breakdown @ 7.5T pulse on PG2 12 no power test shot; alternator bearing vibration forced a CHECK->RECOOL transition 13 TF PLC = 224kA with start @ plasma - Bt=7.87; Ip=1.19; q95=4.52 -1.5s & invert @ 1.2s; good current rise; breakdown @ 7.2T IP=-1160000; PG4=17ms; PG2@.45 14 PG4=18ms; PG2 pulse = 35ms plasma - Bt=7.87; Ip=1.19; q95=4.53 good current rise; lots of hard x-rays! 15 PG4=19ms; NL04=1.1; PG2 pulse plasma - half the hard x-rays - good = 45ms & maintenance = 30V breakdown and current rise 16 PG2=60ms and maintenance =35V plasma - hards almost gone - good breakdown and current rise 17 CAMAC highway errors - no power pulse to reSYNC PLCs 18 PG2=55ms and maintenance=30V plasma - hards gone - good breakdown and current rise 19 PG2=100ms and maintenance=35V plasma - low hards - good breakdown and current rise 20 PG2=150ms and maintenance=35V plasma - low hards - good breakdown and slight hesitation in current rise 21 PG2=200ms and maintenance=35V plasma - good breakdown and current rise 22 Br0=.0062 plasma - good current rise - Br o.k. 23 PG2=275ms and maintenance=35V plasma - good current rise 24 gas test; some EDGE and SPECTROSCOPY data only; PG2=275ms and 35V maint. 25 gas test; some EDGE and SPECTROSCOPY data only; PG2=200ms and 35V maint. |
