1A Gangphase Shifted Suddenly?

17 hours 2 minutes ago
Log Number: 4476876Logbook(s): Entry Makers: bschaumlBody: 

We have been noticing shifts in the 1A SLM which clean up with gangphase adjustments. I have not seen it when it happens, but perhaps we can catch it on SLM1A:Stats1:SigmaX_RBV?

XL Pathlength Adjustment

17 hours 7 minutes ago
Log Number: 4476875Logbook(s): Entry Makers: bschaumlBody: 

We were struggling to get up the 3S ramp and suspected there was an issue with energy due to pathlength. There is definitely some scraping on the m56 readback, but we were able to get an idea of the error... approximately 16.9 mm. Oh no. There was only so much throw on the Dog 2 shunt and DogCalc was bottoming it out so we applied half of the calculated change to Dog 2 manually. This improved the reading to 5.6 mm, but we have no more room on the aforementioned shunt. After the correction was applied we needed to adjust the SL by 18 degrees to bring it back on crest.

IPM3S00 missing from BPM screens. CED shows it with a * (unpowered), however, the hand-built spreader-recombiner screen has this BPM and it's showing response to beam.

Follow-up Re: 2L-2R Viewer Walk

So, this is the cold startup where we are aiming at sending beam to 3R in order to be able to do ARC2/ARC1 M56, poathlength ,etc.. Hence, no match is performed yet (other than INJ->NL). You can see on these plots that the beam is not optimally match.

This will be addressed when we go through the ORFP.
