These are radiation monitoring devices, so the Device Type is RADM:.
The soft hard x-ray side uses DOSFET controllers for undulator dosimeters, so the area will be UNDSUNDH:. The hard soft x-ray side will use the Keithley RadFET system, so the area for those will be UNDHUNDS:. 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 USER_P DEV defined by sensor location, e.g. USER_PDEV=RADM:GUNB:621: for a sensor at location 621 in GUNB, and Aliased internal name is the names used internally 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. Each sensor board has two sensors on it, so the readings have an instance 1: and an instance 2:.
