The list below is a direct copy of the scaler description file sweeperscaler.def. This file maps channel names to channel numbers, and in addition determines the layout. Details about the Sweeper scaler GUI can be found here.
| Channel name | Channel number | Description |
|---|---|---|
| SWEEPER.Source | 0 | Signal going to Sweeper ULM trigger module (generally from “left-up” FP Thin scintillator PMT) |
| 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 (Level3 trigger) |
| Sweeper.Trigger | 4 | Sweeper triggers (“singles”) |
| Coinc.Trigger | 5 | Coincidence triggers (e.g. Sweeper and MoNA/LISA) |
| Ext1.Trigger | 6 | External-1 triggers |
| Ext2.Trigger | 7 | External-2 triggers |
| Second.Trigger | 8 | Secondary triggers |
| Raw.Trigger | 9 | Raw triggers (including all sources) |
| Live.Trigger | 10 | Live triggers (including all sources) |
| Raw.Clock | 11 | Raw clock |
| Live.Clock | 12 | Live clock |
| Thin.LU | 13 | Signals from Left up PMT of FP Thin Scintillator |
| Thin.LD | 14 | Signals from Left down PMT of FP Thin Scintillator |
| Thin.RU | 15 | Signals from Right up PMT of FP Thin Scintillator |
| Thin.RD | 16 | Signals from Right down PMT of FP Thin Scintillator |
| RF | 17 | Signals from Cyclotron RF |
| Pot.Scint | 18 | Signals from Pot scintillator |
| XFP.Scint | 19 | Signals from XFP (A1900 extended FP scintillator) |
