SOL1 20-6 Interlock Help
Solenoid 1, SOLN:IN20:121, or SOL1, will now inhibit station 20-6 rf, the LCLS gun, if its IACT reads below an MPS threshold (see Limits?...)
This solenoid current interlock is generated in the MPS IOC, and it's an input into the vacuum summary box for 20-6. This new interlock will turn off the rf through the waveguide vacuum permit into the MKSU. This fault is non-latching, and it will recover once the solenoid's IACT reads above the threshold. Any MPS ioc or magnet ioc communication error will also fault this input.
In the SCP, this fault, along with any other fault included in the vacuum summary box for 20-6, will show as a waveguide vacuum fault; further details can be found under Gun Waveguide Vac?...
