| ACCL | Used for everything in the RF system that is part of the general physics and operations interface at the cavity level |
| CMOD | Used for everything in the RF system that is part of the general physics and operations interface at the cryomodule level (Gang phase and LEM computations) Comment by Sonya 1/17/18: Remind me why we need this: can't we just use ACCL:L1B:1500:PDES, for example? |
| GUN | Used for everything in the gun |
| Buncher? | |
| PRC/RFS/RES/SSA | Used for engineering diagnostics related to a specific control chassis, such as chassis health monitors. They names correspond to the chassis types: Precision Receiver Chassis, RF Chassis, Resonance Chassis, Solid State Amplifier |

| GACT | Measured gradient from cavity probe (MV/m) | |||
