View source for Pol He3 Target Meeting April 27, 2020

<b>Members present: Jian-ping, Murchhana, Melanie, Arun, Brad, Jixie, Mingyu, Todd, Bill, Junhao, and Mingyu </b>

Murchhana
*Presented slides on Compass measurements
**Settings for the compass measurements were exactly the same as those for the field measurements
**Longitudinal: needed a turning mirror to reflect the laser beam toward the compass (the only difference between the longitudinal and transverse setups).
**Transverse (+x) field direction measurements
***want to compare to Bill’s results
**Horizontal error from mirror alignment
***fit to a line and not an ellipse? how much the trend deviates from a line represents the uncertainties

Junhao
*Completed script that uses Mingyu’s run databse to analyze NMR data
**Put NMR results in the pol-he3 group directory
**can still work on the cdaql1 directory, but be sure to store results in the group directory so it’s backed up
*Need to find out if we can access EPICS variables from the farm
**Cannot seem to get the correction coil settings from EPICS?

Bill
*Can expect shipment for the KEPCO power supply soon


Next week, we expect presentations from Mingyu and Melanie
