Chopper Scan Setup & Measurements with Prebuncher Off

2 days 14 hours ago
Log Number: 4544726Logbook(s): Entry Makers: bschaumlBody: 

C beam used for all measurements. High interception on A2 prompted slight resteering. ITV0I04 viewer captured with attenuator at 100 which corresponds to ~200 nA of CW. Attenuator of 190 = 10 uA, 275 = 40 uA, and 335 = 70 uA.

Figs. 5 & 6 are the chopper viewer with the prebuncher on and off.

Figs. 7-10 show the scans used to find the maximum transmission through the B slit

Figs. 11-13 show some checks on the viewers as I noticed FC1 was only getting ~45 uA of the 70 uA coming off the gun, even with the B slit retracted.

Follow-up Re: SLinac 2K Trip Preparations

Liquid levels have been lowered to a nominal 78%. Most are well behaved, but some (2L05, FL02 as examples) have a periodicity to their liquid levels. Some changes were made to their PID controls to dampen these oscillations, but they should be fine until the planned trip tomorrow morning.

Bleedthrough Measurement LivePlot

2 days 19 hours ago
Log Number: 4544689Logbook(s): Entry Makers: bschaumlBody: 

Script SME took the guardrails causing prior erros off. Reported measurements seem sane based on the data. It seems that the A laser was phased to the C slit so the C bleedthrough measurement reported the full ~13 uA of the A laser through the C slit. This is not a failure of the script. We're repeating a C bleedthrough measurement with the A laser assigned to the C slit which should give us the results we expect.
