    Entry number 284940

    keyword=Happex Triggers, signals, and HV mapping in HRSs

    Left HRS: ---------

    [All channels starting from 1 unless mentioned otherwise]

    S0 front: 1L of S1

    S0 back: 1R of S1

    Happex detector: Gas Cherenkov ch7

    Definition of T1: happex detector signal

    Definition of T2: S0 front ANDed with S0 back

    Definition of T8: 1024 Hz clock

    Other inputs (T3 to T7) to the trigger supervisor will come from PVDIS and will remain prescaled away.

    High Voltage for S0 and happex detector (slot numbering and channel numbering start from zero):

    Happex detector: slot2, ch9

    S0 front: slot2, ch1

    S0 back: slot2, ch7

    Right HRS ---------

    [All channels starting from 1 unless mentioned otherwise]

    S0 front: 1R of S1

    S0 back: 1L of S1

    Happex detector: Gas Cherenkov ch1

    Prex Thin: Gas Cherenkov ch2

    Prex Stack: Gas Cherenkov ch3

    Definition of T1: happex detector signal

    Definition of T2: S0 front ANDed with S0 back

    Definition of T3: Prex Stack

    Definition of T8: 1024 Hz clock

    Other inputs (T4 to T7) to the trigger supervisor will come from PVDIS and will remain prescaled away.

    High Voltage for S0, happex, and Prex detectors (slot numbering and channel numbering start from zero):

    Happex detector: slot 14, ch9

    S0 front: slot 14, ch1

    S0 back: slot 14, ch3

    Prex Stack slot 14: ch5

    Prex Thin: slot 14, ch7
