IA Driver Crosstalk Measurements

3 hours 51 minutes ago
Log Number: 4472803Logbook(s): Entry Makers: suleimanscovertBody: 

This morning we measured the Hall C IA output on the oscilloscope, and exercised the Hall A & B outputs to verify if there was any crosstalk during operation.

Tl;dr: We did verify that when operating the IA outputs in an aggressive manner (pushing towards the limits of the outputs) the existing IA driver does have crosstalk across channels.

Log Number: 4472801Logbook(s): Body: 

Per Riad's request, the JLab RTP drivers have been renamed "JLAB-RTP-HV-1.1" and "JLAB-RTP-HV-1.2". With this "X.Y" naming nomenclature, X denotes the revision, and Y is the serializing number. E.g. "1.2" indicates first revision, second box. The spare box we will build will be "1.3" and so on.

Log Number: 4472787Logbook(s): Body: 

Present GSET.DRVH values and ODVH values for 1L05: https://logbooks.jlab.org/entry/4472783
CED workspace created and being merged now to take GSET.DRVH values to 21 for that zone for pulse processing. Please be sure to monitor radiation on NDXs there and downstream as it is processed and do a unit test of all 8 cavities for cryo heat load & radiation measurement when processing is complete.
