| MP355 RF Conditioning Session leader: Wukitch Physics operator: Snipes Overnight ECDC in D2, and bake at 60 C. Run begins at 09:00 and ends at 17:00 Power systems as on 1060321028 (1.0 MA fiducial, 5.4 T, lower single null) A-coil configuration: normal [+Dtop -Dbot -Jtop +Jbot] and enabled. Gas Setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 1 psi Ar + 2 psi Ne Hybrid DISABLED (PG1) leave B-side upper as is Hybrid DISABLED (PG2) fill B-main (C-side) with 40 psi D2 Hybrid enabled (PG3) fill NINJA with 12 psi D2 Enabled Enable the following gate valves and shutters, assuming no vacuum problems: ECE, VUV, Z-bolo shutters Torvac setup: Gate valves open Important Diagnostics: magnetics, standard impurity spectroscopy ------------------------------------------------------------------------------- ICRF Setup: FMIT#1-4 in run-on by 08:30. ------------------------------------------------------------------------------- Plan: Continue machine cleanup and ICRF conditioning (including Jport) in fiducial discharges. |

| This run was a bust from the get go. Or rather, we never got a get go. The alternator problem cancelled the run after only three gas test shots (before I arrived) that all went well. The alternator diagnostic should be repaired later today and be ready for tomorrow's run. |

| Mar 22 2006 08:15:33:820AM | 1060322001 | Jim Irby | Cycle test to check out the static fill for intra-shot use.
B-Top was used at 6 psi D2, FILL SELECT only, no HYBRID ENABLE. Asked for 5e-5 Torr controlled by IGT Got 4.8e-5 to 4.9e-5 Torr with 30.3 volts on piezo. Ratiomatic indicated about a factor of 4 more pressure: 0.21 mTorr |
| Mar 22 2006 08:15:19:383AM | 1060322002 | Jim Irby | Cycle test to check out the static fill for intra-shot use.
B-Top was used at 6 psi D2, FILL SELECT only, no HYBRID ENABLE. Asked for 5e-6 Torr controlled by IGT. Got 4.4e-6 Torr with 22 volts on piezo. Ratiomatic: 0.02 mTorr |
| Mar 22 2006 08:16:04:757AM | 1060322003 | Jim Irby | Cycle test to check out the static fill for intra-shot use.
B-Top was used at 6 psi D2, FILL SELECT only, no HYBRID ENABLE. Asked for 1.5e-5 Torr controlled by IGT. Got 1.4e-5 Torr with 24.8 volts on piezo. Ratiomatic: 0.062 mTorr |

| Mar 22 2006 08:56:54:710AM | 1060322003 | Joseph Snipes | There will be a long delay due to the alternator, at least a couple of hours. |
| Mar 22 2006 10:22:52:413AM | 1060322003 | Joseph Snipes | The alternator needs to turn off to replace a part and since it will take most of the day to bring it back up, we will scrub the run and make this a maintenance day. |
