    keyword=Dead time reading

    Shift crew should be aware that the deadtime reading in datamon is not operational yet. Bob will probably make it work once we tell him what scalers we use for dead time measurement.

    Right now dead time is about 25% with 60Hz data acquisition rate.

    Dead time can be calculated as: 1-T10/T5. Right now T10 is double-pulsing (different issue), so you can use 1-T15/T5. In the xscaler gui:

    -T10: HRS singles -T15: Electron-trig
