RadFET (the sensor) and DOSFET (the control box) Names

These are radiation monitoring devices, so the Device Type is RADM:.

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.

PVs that apply to one RadFET sensor module

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 DOSFET radiation dose readings have an instance 1: and an instance 2:. For the Keithley/SXR system, the sensors are wired in parallel and read out together, so the INST field is not used. It does not have a temperature sensor.

PVs that apply to the whole DOSFET chassis

In this table, DEV is a chassis name. One DOSFET chassis has four of the sensor modules defined above. One Keithley system has 112 modules.

NOT APPEARING ON ANY SCREENS

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 (not exposed on screens) which reflect the chassis channel labeling and manufacturer's documentation, e.g. P=RADM:GUNB:RM01: and SENSOR=B for channel B of the second chassis in GUNB. SENSOR on the chassis side is A, B, C, or D.
