The # "name" is the EPICS variable name. # # # freq.(s) name # --------- ----------------------- #================================================ # The following are from e-mail responses to a # request made for the variables that should go # in here. Most of the EPICS variable names # either don't yet exist or need to be tracked down. # # 6/25/2014 DL # From Curtis: # 1) Atmospheric pressure in the hall ~every 15 minutes # 2) Chamber gas temperature ~every 15 minutes # 3) Chamber gas flow?? ~every 15 minutes # 4) Chamber gas mix?? ~every 15 minutes # From Richard: # # This message is just a placeholder, as I don't know yet # what the best format for this information will be (number # of bytes, variables to store, frequency) but I would like # there to be a regular storage of the active collimator beam # offsets and total current to the event stream. # #-Richard J. # # From Ken Livingston: # # Form the coherent brem perspective, the following would be required at # 2s intervals. # These are not proper names yet # # goni_axis 1,2,3,4,5 # coh_edge # coh plane # coh radiator # # ladder scalers / microscope scalers - possible some scalers from the # pair spec. # # It's the read of the scalers at 2s intervals that enables the coherent # edge to be reconstructed and tracked. # # In hall B, the goni params etc were in a 2s epics event and TESC, the # tagger scaler was inserted every 2s as a special bank created from the # epics waveform array (376 elements). # # Regards, # Ken # From Richard (again): # Hello David, # # For the microscope, I would like to have a set of key voltage levels and temperatures in the frontend recorded in the event stream. # # -Richard J. # From Mark D.: # If it was available we would definitely use it. So far, the things we would have be interested in are the module temperatures and maybe some crate temperatures or the hall temperature. # # Best, # Mark Macrae Dalton
