The list below is a direct copy of the scaler description file for the s800. This file maps channel names to channel numbers, and in addition determines the layout. Details about the S800 scaler GUI can be found here.
Channel name | Channel number | Description |
---|---|---|
S800.Source | 0 | Signal going to S800 ULM trigger module (generally from “up” FP scintillator photomultiplier, E1 up) |
Second.Source | 1 | Signal going to Secondary ULM trigger module (e.g. GRETINA) |
Ext1.Source | 2 | Signal going to External-1 trigger module |
Ext2.Source | 3 | Signal going to External-2 trigger module |
S800.Trigger | 4 | S800 triggers (“singles”) |
Coinc.Trigger | 5 | Coincidence triggers |
Ext1.Trigger | 6 | External-1 triggers |
