[Halld-pid] Naming the TOF HV channels

Tue May 13 09:26:20 EDT 2014

Nerses,

Fernando is correct.  

We need to follow the GlueX convention.    We do not want to have HV cable labels, off line channels, and slow control channels with names that differ.   

Hussein will show this naming in his update today, but I attached a few highlights.

On a more general note.  You have implemented a naming scheme for other slow control systems.   You should check that they follow the GlueX standard (i.e. you can just look at the HV cable labels or talk with Fernando).

Paul

To change these later values from letter to number would would require a change of the [1,2] to something like [H(orizontal),V(ertical)]. I say we keep it as you propose, but I will pass this information on to others in the TOF group for their concerns.
