| Run Plan for Tuesday June 19, 2001 1010619 MP215 J-port Conditioning SL: Boivin PO: Marmar Engineering setup: ECDC in D2 overnight Run starts at Noon Power systems as on 1010612014. Gas setup: fill B-top with 6 psi of D2 Hybrid enabled (PG4) fill B-side lower with 1 psi of Ar Hybrid enabled (PG1) fill B-side upper with 30 psi of D2 Hybrid DISABLED (PG2) fill C-side with 30 psi of D2 Hybrid enabled (PG3) fill J-bottom with 30 psi of He Hybrid DISABLED (PG5) Enable the following gate valves: ECE, DNB, and VUV. Open the Z-bolo shutter for plasma shots (closed during ECDC). Be set up for between-shot ECDC. Run plan: The goal of the run is to continue bringing J-port into full operation.

The antenna was conditioned to 32 kV prior to the run. J-port power was increased to 1.5 MW into H-mode but the still has numerous faults. D-port was completely unreliable in stark contrast its last operation (1010608). |

| Physop run summary 1010619 Run Plan for Tuesday June 19, 2001 1010619 MP215 J-port Conditioning SL: Boivin PO: Marmar Engineering setup: ECDC in D2 overnight Run starts at Noon Power systems as on 1010612014. Gas setup: fill B-top with 6 psi of D2 Hybrid enabled (PG4) fill B-side lower with 1 psi of Ar Hybrid enabled (PG1) fill B-side upper with 30 psi of D2 Hybrid DISABLED (PG2) fill C-side with 30 psi of D2 Hybrid enabled (PG3) fill J-bottom with 30 psi of He Hybrid DISABLED (PG5) Enable the following gate valves: ECE, DNB, and VUV. Open the Z-bolo shutter for plasma shots (closed during ECDC). Be set up for between-shot ECDC. Run plan: The goal of the run is to continue bringing J-port into full operation. Summary: This was a tough run from the physop point of view. We started at about 1:00 pm. J-port had vacuum conditioned in the morning. The run started with 4 duds followed by 4 fizzles. Then we got 3 plasmas, a fizzle, a dud and finally a plasma. All field and gas changes were small. A leak started to open up around 2:30 pm, and by the end of the run, mass 28 was at 1.2e-7 on the RGA. After the run, it was determined that parts of F-port were iced up. The RF did run on the 4 plasmas. See the logbook for details. Scorecard: Plasmas -- 4 Fizzles -- 5 Duds -- 5 total cycles 14 |
