Notes by R. Jones
Preparation for the CHESS run in two weeks
Note from Franz Klein:
- I have the goniometer target ladder at home: the 'good 50' looks more darkened than 2 1/2 years ago - for sure an interesting comparison to do! I copied the goniometer and beam info from g13 (and parts of g9). I probably cannot give you a pixel-to-pixel variation of the charge but for a position information of ~100-150 microns.
- It would be good to find out when Ken wants us to be at CHESS; the last times he spent a day or so to set up the beamline - it would be good to know whether he is doing that on Friday or the weekend? Talk to you later this week.
Prep for tagger design internal review at JLab
Discussion with PrimeX collaborators
Ashot/Lipeng: Suggesting perhaps tagger end-point work or pair spectrometer? MRI?
The pair spectrometer is currently the piece most conspicuously lacking stewardship. The higher energy resolution requirement will demand precise field maps, likely for both tagger and pair spectrometer magnets. Understanding of stability of these values over time will be important.
