| Session Leader Run Summary for 1010705 MP291A LFS ITB Return of Son of 049A. Shot 3 had a brief ITB just prior to the disruption, at 4.5 T, to confirm the earlier results. The rest of the run was plagued by disruptions, presumably due to a loose RF probe coaxial cable, and no useful data relating to low field side ICRF ITB formation were obtained. |

| Jul 5 2001 08:46:13:893AM | Ian Hutchinson | MP291A ITB with low field side ICRF. SL Rice PO Hutch Cold start PCS load from 1001220016 | |
| Jul 5 2001 09:05:38:680AM | Ian Hutchinson | Import segment 1 from 1010629010 Load | |
| Jul 5 2001 09:24:08:577AM | 1010705001 | Ian Hutchinson | Plasma. Density rises rather slowly and then gets a big puff. ECDC between shots. Raise early nlzmeter. Set flat top level to .6 instead of .7 |
| Jul 5 2001 09:46:00:930AM | 1010705002 | Ian Hutchinson | Plasma. Still no J-port Go to 150kA TF from 124. Load segment 2 from 1010703001 Load nlzmeter from 1010705002 wire 14 |
| Jul 5 2001 10:07:43:033AM | 1010705003 | Ian Hutchinson | Fizzle IEF4 to -1300 from -1290. |
| Jul 5 2001 10:26:26:930AM | 1010705004 | Ian Hutchinson | Plasma. Disrupts soon after E-port comes on. Big injection. IEF4 to -1280A |
| Jul 5 2001 10:59:37:977AM | 1010705005 | Ian Hutchinson | Plasma. Disrupts at .7 s again. nlzmeter to .5 from .6 |
| Jul 5 2001 11:23:14:040AM | 1010705006 | Ian Hutchinson | Plasma. Disrupts at .65s. Looks as if D-port must be the problem. No E. and J does not try till after the injection. Delay D-port. Remove TF wiggle. |
| Jul 5 2001 11:38:03:910AM | 1010705007 | Ian Hutchinson | Dud. Fields don't look too bad, although the sequence had some funny problem. |
| Jul 5 2001 11:54:40:457AM | 1010705008 | Ian Hutchinson | Dud Raise fill puff from 19ms to 24ms. IEF4 to -1285 from -1280. |
| Jul 5 2001 12:25:05:877PM | 1010705009 | Ian Hutchinson | Plasma. Disrupts at .83s, shortly after the delayed D-antenna turns on. Turn off D-port. |
| Jul 5 2001 12:36:39:117PM | 1010705010 | Ian Hutchinson | No power shot. Network hang. |
| Jul 5 2001 12:44:33:680PM | 1010705010 | John Rice | canonical noontime data system hang no power shot |
| Jul 5 2001 12:45:35:603PM | 1010705011 | John Rice | D port antenna causing disruptions so-so EDA at 5.4 T, and with only J and E power |
| Jul 5 2001 12:54:13:383PM | 1010705011 | Ian Hutchinson | Plasma. Nice sustained EDA at 1.75MW. Load segment 2 from 1010507001. Nlzmeter to .5. Load |
| Jul 5 2001 01:13:27:190PM | 1010705012 | Ian Hutchinson | Fizzle. F-side pressure is .09. Probably because the ECDC had been run. Enegineering reports that init was entered at 5e-4, and an extra 30s was added to the wait to enter check to compensate. However, the network was much speeded up. So that might not be enough. IEF4 to -1290 from -1285 |
| Jul 5 2001 01:33:23:600PM | 1010705013 | Ian Hutchinson | Plasma. Disrupts at 1.3s as the late D-port power ramps up. ITF to 130kA. Try to get a decent shot with not such a low field. Entered check at pressure: 2.5e6 |
| Jul 5 2001 01:45:45:890PM | 1010705014 | Ian Hutchinson | Fizzle. Fill is .084 ITF back to -124kA |
| Jul 5 2001 02:06:22:803PM | 1010705015 | Ian Hutchinson | Plasma. Disrupts at .26s. Fill .073 Seems as if the clearin is messed up for this shot. Has zero offset. Incorrect. So load from 1010703001 (again). Change ITF V. Load nlzmeter from previous shot. |
| Jul 5 2001 02:23:14:383PM | 1010705016 | Ian Hutchinson | Plasma. Disrupts at 0.8s. No J-port. power. |
| Jul 5 2001 02:39:58:883PM | 1010705017 | Ian Hutchinson | Plasma disrupts at .72s. ITF to 160kA. |
| Jul 5 2001 03:03:17:163PM | 1010705018 | Ian Hutchinson | Disrupts at 0.5s. Found the problem on the wide angle. A wire or other object is poking up at K port and glowing and blowing off junk. It first became unmistakably visible on shot 9. There was some sort of activity in the same general area on shot 1 but not what we have now. Shut down the run to figure out what to do. |
