    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
