This page gives definitions of the condition variables stored in the RCDB as of RunPeriod-2016-02.
| Condition Name | EPICS variable | Notes |
|---|---|---|
| beam_current | IBCAD00CRCUR6 | Beam current from electron dump (?) BCM, averaged over run, in nA |

| ps_converter | hd:converter_at_[home,a,b,c] | 5 x 10-3 RL, 1 x 10-3 RL, 3 x 10-4 RL, Retracted |
| solenoid_current | HallD-PXI:Data:I_Shunt | Measured current in solenoid magnet, in A |
| status | N/A | For future use |
| radiator_index | HD:GONI:RADIATOR_INDEX | Goniometer radiator position index, as described in this page. |
| radiator_id | HD:GONI:RADIATOR_ID | Goniometer radiator unique ID, as described in this page. |
| polarization_direction | HD:CBREM:PLANE | Direction of the photon beam linear polarization with respect to the floor: PARA, PERP, or UNKNOWN |
| radiator_type | HD:GONI:RADIATOR_NAME OR hd:radiator_at_[a,b,c] | Goniometer radiator name, as described in this page, Amorphous radiator (2 x 10-5 RL, 1 x 10-4 RL, 3 x 10-4 RL), or retracted |
| target_type | HLD:TGT:status | Status of LH2 target: OFF, Cooling, Filling, FULL & Ready, Emptying, EMPTY & Ready |
Other Notes
- When the nA BPMs are calibrated, we could use another variable for the beam current that might be more accurate for lower (<1 uA) currents, e.g. IPM5C11.VAL,IPM5C11A.VAL,IPM5C11B.VAL,IPM5C11C.VAL
