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.
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 sensors on it, so the readings have an instance 1: and an instance 2:.

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.
