There are two sets of decarads (10 heads + central unit) so the PVs listed above are doubled and differentiated by $(P).
Suggested $(P) = RADM:SYS0:100 or RADM:SYS0:200 for the two systems.

To Do:

  • PV names approved
  • Test save/restore and see what values HVSTAT gets
  • Release EPICS software
  • Release display, add button to another display to open it
  • Test software: displays, save/restore, archiving
  • Build frames
  • Buy carts, cables, cable reels, connectors
  • Make DB9/RJ50 cables
  • Ask Charlie to configure Digis
  • Assemble carts and extension cords and enet cables on reels
  • Cable tags - so know which cables are short (use in the middle (4-7)) and which are long (use on the ends (1-3, 8-10)? And in case need to connect to central box.

Introduction

The Decarad system was developed at JLab - it consists of 10 radiation detecting heads (geiger-mueller (GM) tubes) that connect (signal & HV cables) to a central box. That box has a board inside for changing the HV level and reading out the GM tube signals. The center box is connected to a digi port server via DB9 at box to RJ50 at the digi, which is then connected to the outside world via ethernet. The software uses the epics tool Stream with an asyn connection to the digi to send commands to the center box to read and write. The software is part of the RadiationMonitoring slac epics package.
