ILM3R10 Update

1 day 1 hour ago
Log Number: 4536305Logbook(s): Entry Makers: bjacobBody: 

I've been talking with optics on call and they noted that 9R seems to deviate from the rels more than the other Odd R regions. They also noted that this deviation may be starting in Arc 8. So this may be a spot to check.

However, checking would mean halting beam and doing more steering. After talking with the Hall C folks, they've indicated that 65 uA is fine for now. So the plan for now is to stick with 65 uA until Monday when more folks are around. Of course, if the BLM trips get worse, we may need to address it sooner.

Steering to try and quiet ILM3R10

1 day 3 hours ago
Log Number: 4536270Logbook(s): Entry Makers: bjacobBody: 

I took a brief look around the machine to see if I could see what is irritating ILM3R10. I cleaned up a lot linacs and R regions but nothing I did really stopped the spikes we were seeing. I left the changes in since they didn't hurt anything and the linacs look better.

I tried putting in dumplettes in descending order and found that the spikes stop when putting in the 4R dumplette. I took a closer look at 4R-5R but still couldn't find the magic knob.
