| Engineering Setup and Run Plan 1040301, Monday, March 1, 2004. MP#355 RF commissioning (50MHz) MP#390 D(He3) minority heating Session Leader: Wukitch Physop: Rowan Engineering Setup: ECDC through the weekend in D2, stopping by 07:00 on Monday morning Run Begins at 09:00 and ends at 17:00 Power Supplies as on 1040218003 Gas System Setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 1 psi Ar Hybrid enabled (PG1) leave B-side upper with 15 psi He3 Hybrid DISABLED (PG2) fill C-side with 30 psi D2 Hybrid enabled (PG3) fill NINJA (lower cap) with 5 psi He All diagnostic valves (ECE, VUV, DNB) Enabled assuming no vacuum problems RF: Transmitters #1,2,3 and 4 in RUN-ON by 08:00 ------------------------------------------------------------------- Initial discharges will be Fiducial discharges (1 MA, 5.4 T, nl_04=0.8) 1040218003 1. Find the match needed for J antenna at 50 MHz Find the proper antenna phase settings Determine if matching network is working properly. 2. Raise power until 2 MW power level is obtained. May need to add 3He puff if impurities or antenna are problems. Could lower field to 3.5 T instead. 3. If successful, begin MP390 and lower field to 5.2 T. 4. Scan 3He concentration by varying the gas puff pulse width (0, 5, 10, 15, 20, 15, 10, 5, 0 msec pulse width with no maintenance level). Continue the scan till mode conversion can be localized. The RF waveform will have J-port followed by D and E-port ramped to 3.0 MW as programmed on 1030710005. 5. Using 2.5 MW constant power, scan gas puff pulse widths (0, 5, 10, 15, 20, 15, 10, 5, 0 msec pulse widths) and monitor plasma response to compare H-mode performance. 6. Using optimum gas puff, scan phase ? ramp power to 3 MW and constant 2.5 MW. 7. For optimum gas puff, scan plasma density [0.6, 0.8, and 1]. 8. Using optimum gas puff and USN (1040218016), ramp power to 3 MW to investigate H-mode threshold. 9. Using same target discharge, plasma response with combined D, E, and J-port with a fast turnoff on J-port.

We were able to obtain a match for J4 but J3 appears to have a transmitter problem. The other "small" problem was RF interference on almost all diagnostics particularly the magnetics (apologies to all the others who experienced problems). We tested #4 into load and were free of interference problems. This suggests the source of the problem is in the cell. |

| Physics Operator Summary for Run 1040301, March 1, 2004 Purpose MP#355 RF commissioning (50MHz) MP#390 D(He3) minority heating Session Leader: Wukitch Physics Operator: Rowan Engineer Operators, Dekow, Byford, Parkin Summary----------------------------------------------------------------------- Only MP 355 was addressed today. The run suffered from numerous problems, but there was some progress with regard to identification of RF pickup on various systems. See SL summary for details. There were several data system hangs which caused significant loss of time. After shot 022, PCS crashed and required restart. The TCI was intermittent and beginning with shot 018, the gas fueling was controlled by fixed programming. By the end of the run, it was clear that pickup from the RF was causing drift on the magnetics signals and hence causing potential control problems. Various other alarms including diborane were spuriously tripped by the RF pickup. Scorecard-------------------------------------------------------------------- Plasma 17 (003,004,009,010,011,012,013,014,015, 016,017,018,020,021,022,023,024) Cycle Test 2 (001,002) Plasma Disruption 1 (019) due to power supply failure No power shots 4 (005,006,007,008) due to computer problems Total 24 Engineering Setup-------------------------------------------------- ECDC through the weekend in D2, stopping by 07:00 on Monday morning Run Begins at 09:00 and ends at 17:00 Power Supplies as on 1040218003 Gas System Setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 1 psi Ar Hybrid enabled (PG1) leave B-side upper with 15 psi He3 Hybrid DISABLED (PG2) fill C-side with 30 psi D2 Hybrid enabled (PG3) fill NINJA (lower cap) with 5 psi D2 All diagnostic valves (ECE, VUV, DNB) Enabled assuming no vacuum problems RF: Transmitters #1,2,3 and 4 in RUN-ON by 08:00 Reduce TF from 5.4 T which was used for 1040218003 to 5.2 T Detailed Log--------------------------------------------------- Loaded shot from 1040218003 Segment 1 was changed in the course of this run due to duds.
