[Halld-pid] Naming the TOF HV channels

Tue May 13 13:37:25 EDT 2014

Hi Paul,

No, we are not changing the rules now as everything is already 
standardized following GlueX-doc-2293, which is the final document on 
labeling. This has been the case for years and all the cables are 
already labeled for all detectors, and correctly. Nerses and everyone 
else have had this document for years and the TOF has been set for that 
long also and all the cables and PMTs are labelled correctly now.

GlueX-doc-2019 is dated to 2008, if you look carefully. This was 
actually a slide I presented at a collaboration meeting to serve as 
guidance wrt the detector orientation in the hall. Granted that not many 
people were involved with these issues at the time but if you look 
carefully, all the labels were not "as built". For instance the FCAL has 
no specifics on the beam "hole"; the TOF does not have two PMTs, the 
BCAL has layers, etc.

So, let's stick with norm: GlueX-doc-2293.

Best regards,
Fernando
