[Pansophy] LCLS2 cavity eccentricities

[Michelle Oast]

Hi Megan,
For Zanon, it's in Holdpoint 2:

For RI it's also holdpoint 2, but please use all 4 travelers that correspond to that holdpoint (CAVEZ-CAVEZ4):

Thanks so much for your help!

Michelle,
For LCLS2, I made travelers that pulled in the vendor data from Zanon and RI (pictured below). My thought was to figure out what the field names are that these were taken in, we can do a user defined query. I don't really know which "holdpoint" these values came in. If you could figure out what fields this data went in, I can help with the data retrieval

Hi Megan and Valerie,
Gary and I are working on defining a possible issue with LCLS2 cavity alignment.  In order to determine the severity of the problem, I need to know the most eccentric cavities from the LCLS2 cryomodules.  I'm hoping either of you could produce something similar to the plots below (pg. 36 of attached tech note):

At the top is the vendor data (I've attached an example excel sheet) and the bottom are plots including the eccentricities for all cavities produced by each vendor (what I'd like to have).  The cavity vendor eccentricity data sheets from L2 are linked below, please let me know if you have issues accessing.

If you have any questions please let me and Gary know.
Thanks,
Michelle
