    keyword=New EPICS Variables for He3 Target Status

    New EPICS Variables, which are designed to pass target status into data
    stream, are loaded into target IOC (129.57.188.42). They are also
    tested to be read/writable from target control computer & drawable from
    EPICS strip chart tools.

    LIST OF VARIABLES

    Name Type Range
    Descriptions

    haPolHe3_Spin_State Enum/Int -1;0;1 +-1=two
    different spin state; 0=undefined state

    haPolHe3_Flip_Sequence_ID Unsigned Int32 1 to inf ID
    number for current flip sequence

    haPolHe3_Flip_Count Unsigned Int32 0 to inf How
    Many Flip Since Last Calibration

    haPolHe3_EPR_ID Unsigned Int32 1 to inf ID
    number for last successful EPR measurement

    haPolHe3_EPR_POL Double -1 to 1 Last
    EPR Measured Polarization

    haPolHe3_Last_Flip_Start String Last
    Flip Start Time

    haPolHe3_Last_Flip_End String Last
    Successful Flip Finish Time

    haPolHe3_FLIP_NMR_PHASE Double 0 to 7 Phase
    (between X and Y Channel at Peak)of NMR read out during last Flip

    haPolHe3_FLIP_NMR_Mag Double 0 to inf Peak
    Magnitude of NMR read out during last Flip

    haPolHe3_FLIP_NMR_Pol Double 0 to 1
