The hard x-ray side uses DOSFET controllers for undulator dosimeters, so the area will be UNDH:. The soft x-ray side will use the Keithley RadFET system, so the area for those will be UNDS:. Some sensors and one DOSFET box will be in the dump area.
In this table, the "PV Name" column defines the user/programming interface with DEV defined by sensor location, e.g. DEV=RADM:GUNB:621: for a sensor at location 621 in GUNB. Each sensor board has two radiation dose sensors and one temperature sensor on it, so the radiation dose readings have an instance 1: and an instance 2:.
| PV Name | Type | Description |
|---|---|---|
| $(DEV):$(INST):RAW | ai | Raw voltage readback. |
| $(DEV):$(INST):ZERO_VOLTS | ai | Raw voltage at corresponding to 0 accumulated dose. |
| $(DEV):$(INST):DELTA_VOLTS | ai | Raw voltage difference, from 0 to now. |
| $(DEV):$(INST):DOSE | calc | Accumulated dose. Calculated from DELTA_VOLTS, with an equation in the CALC field configured by radiation physicists |
| $(DEV):$(INST):RAW_STATUS | mbbi | Sensor status. ("Ok", "Over Linear Range", "Error") |
| $(DEV):TEMP | ai | Temperature of the sensor board, C. |
| $(DEV):$(INST):SET_ZERO_VOLTS | bo | Expert screen, define latest voltage readback as 0 dose |
| $(DEV):$(INST):ZERO_TOD | stringin | Date/time string when dose was zeroed, i.e. latest voltage readback defined as ZERO_VOLTS |
In this table, DEV is a chassis name. One DOSFET chassis has four of the sensor modules defined above.

| $(DEV):POLL_DELAY | ao | Dose readback sampling interval readback |
| $(DEV):GATE_POLLING | ai | Counter for seconds since the last dose readback cycle |

In this table, the "PV Name" column defines the user/programming interface with DEV defined by sensor location, e.g. DEV=RADM:GUNB:621: for a sensor at location 621 in GUNB, and "Wrapped internal name" is the names used internally, for which "PV Name" is a wrapper , but (not exposed on screens) which reflect the chassis channel labeling and manufacturer's documentation, e.g. P=RADM:GUNB:201: and SENSOR=B for channel B of the chassis at location 201 in GUNB.
