Low gain cavity
Polarization Measurements
Gradually this will become instructions to take and analyze data to determine the laser polarization for the Hall C Compton.
Taking Data: Labview Program
Data Analysis
- Use winscp on cpslow to copy data across to the cdaq cluster
Transfer function data in 2D mode
- use ../fit/compilealldata_3D.pl to put a single channel vs 2D indep. variables
- eg. ../fit/compilealldata_3D.pl TFscanHiResEntrance_Jul13_2012 output/TFscanHiResEntrance_Jul13_2012_RRPD output/TFscanHiResEntrance_Jul13_2012_RPD
- use ../fit/TF_constant_subtract.pl to remove the pedestal
- eg. ../fit/TF_constant_subtract.pl TFscanHiResEntrance_Jul13_2012_RRPD 32755 TFscanHiResEntrance_Jul13_2012_RRPD_constsub
