Introduction:
The Cavity Summary Display is similar to the Klystron displays used in LCLS and FACET, but instead of displaying klystron information, the Cavity Summary Display shows cavity faults for all cavities in cryomodules 01 - 35. The GUI also displays whether a cavity's SSA is on and whether or not is has RF.
How to Launch the GUI:
To launch the Cavity Summary Display locally at an OPI, follow the instructions below:
- Open a terminal
- Type in set_profile srf
- Type srfhome. This will launch a PyDM version of SRF Home
- Click "Cavity Summary GUI." This is a PyDM GUI and typically takes 2-3 minutes to launch, so be patient!
Using the GUI:
Now that we've launched the GUI, we want to use it to help us troubleshoot and keep an eye on cavities. The GUI is broken up into the four linac regions (L0B, L1B, L2B, and L3B) each with their own cryomodules (abbreviated as CM). L0B has CM01, L1B has CM02 - CM03 as well as special harmonic linearizers stations CMH1 - CMH2, L2B has CM04 - CM15, and L3B has CM16 - 35. Each cryomodule has 8 cavities.
