Claudia | Restarting Target Current & Line Current |
0) If target or line drop, STOP THE BEAM!!
1) If you SEE target or line current go down (top right window of monitors next to the corridor):
Use Knobs open application (monitor below); remember set value; type 0 in set window; click Mode - Reset; click Mode - On. increase current in steps of 100 A
2) If Target or line current off and it happened a while ago
Use Knobs open application (monitor below); type 0 in set window; click Mode - Reset; click Mode - On Use Isolde Target heating GPs application (in monitor below); |

Comments: First laser does not have a red peak at the center, but maybe okay for this shift.
Attaching PSB and GPS screenshots, as we need to monitor them regularly.
At 6:18 to 6:40, we started getting four rings from the PS Booster. The 1st ring had a fairly low intensity, and the operators later dropped it. These times were confirmed
exactly with communication with PS operators.

Scalars 0 and 1 (see https://elog.ph.ed.ac.uk/ISOLDE/49 ) were in at the beginning of the run. Scalar 2 was added part way through. LEMO cables were not long enough to add 3 &
4 until after the run was stopped (swapped short cables for longer ones elsewhere.)
Scalar 0 was showing a number of multiple hits. It was directly from the Fan In / Fan Out. At the end of the run, I switched it to the Lecroy 622 which has a larger width.
We stopped because the PS-Booster called about cleaning one of the rings. (At first I misunderstood exactly what was going on or who called, but I stopped.) |
