Mike, let us know when the subcontractor will be in to perform this work for the sake of adding it to the SAM calendar.

Thanks,
Daniel

1L10 was pulsed processed and had FE onset measured on 3/2/26. We were busy campers last winter.

1L09 was pulse processed on 3/10/26 had FE onset measured on on 2/11/26 and 3/11/26.

2L05 was processed around 3/8/26 and FE onset data was taken on 4/23/26.

Assuming that we are using the gradient calibrations from commissioning and the data in the summary found at: M:\asd\asddata\CMTF\C75 Tests\C75-05 none of the cavities meet the metric of FE onset less than 13 MV/m AND Quench below 21 MV/m (ideally less than 18 MV/m) that justify doing pulsed processing. At higher FE onset values it is kind of 50/50 if that they will get moderately worse.

Just a quick comment - please check/confirm with the Magnet LDRD group which sample locations you would like to use. We'll be down there, so can work with you.

Performed the measurement and spot move this morning to see if it will improve bleedthrough.
QE at new spot: https://logbooks.jlab.org/entry/4505992
Method and observations: https://logbooks.jlab.org/entry/4505994
Very minor revisions of code and procedure are needed, but by far the biggest problem and reason for time spent on this procedure this morning is reproducibility of the x/y stage; homing it changed the coordinate system unpredictably several times. This will be addressed on the laser table when we get the opportunity.

Preparing for QE scan and spot move.
Allsave as found #27223.
Current laser spot: 13250 / 18750
Tested all four corners of rectangle (12500...15000 in x, 17500...20000 in y), TM A, need about attenuator 350 to see wiresum > 1.0 on the first three BPMs.
Homed x/y stage and moved back to previous position. Slight change in beam orbit, Figure 1.
Zeropos.
Tried calibration run; FSD tripped due to cryomodule.

HOMEWORK: add to procedure to mask these FSDs to avoid the problem.

Starting over: Restored allsave, moved laser back, reproduced Figure 1.
