Engineering setup for Tuesday 4 Dec 2007 MP#298a: C-Mod Startup and Conditioning Physics operator: E. Marmar ECDC overnight in D2 and bake at 60 C. Run will start at 09:00 and end at 17:00. Power systems as on 1071129029. NOTE: WE MAY WANT TO DO BETWEEN-SHOT ECDC. A-coil configuration: +Dtop -Dbot -Jtop +Jbot; Enabled (standard configuration) Gas Setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 1 psi Ar Hybrid DISABLED (PG1) leave B-side upper as is Hybrid DISABLED (PG2) fill B-main (C-side) with 40 psi D2 Hybrid enabled (PG3) leave NINJA as is DISABLED Enable the following gate valves and shutters, assuming no vacuum problems: ECE, VUV, Z-bolo (Do not enable DNB gate valve.) Torvac setup: gate valves open after the shot (but we may change this during the run). ICRF: Not required, but assuming it doesn't cause startup problems, ICRF can do between-shot conditioning into vacuum LH: Not required Plan: Start from 1071129029. If plasma is cleaning up, raise current and density.

In the end, a decent day. We got off to a very slow start. The first shot disrupted at .72 seconds, and then we had 12 consecutive fizzles. The null looked wierd, and Steve Wolfe noticed that OH1 was 300 A more negative than we were programming. This is a power supply problem that also occurred last May. Adding integral gain (4) between -.1 and 0 seconds solved the problem. After that we had many full length plasmas, including 1 MA SNL, and .8 MA USN. J-port was also exercised. From shot 21 on the gate valves were closed during pulse and for the first 300 seconds in recool. Scorecard: Plasmas: 13 Fizzles: 16 Duds: 0 Total cycles: 29
