Go to Pulsed LLRF display | Open embedded or start a script? |
Set the drive level to 15% and RF On Time to 70 ms. Push "Go." Waveforms will appear and display the calculated cavity voltage based on the Loaded Q calculated above. | |
Verify the radiation monitor is logging for the cavity. | |
Slowly increase the Drive Level in 5% steps manually (clicking "Go" after each change) until the cavity amplitude reaches AUSE_SRF or the radiation level exceeds 50 MR/hr (0.5 mSv/hr) | |
Record the maximum Drive Level used | Push button to store in python variable. |
If the cavity faults before reaching 16.6 MV or the usable amplitdueamplitude:
| Maybe some buttons to help here or at least show the interlocks |
Lower the Drive Level to 20% and turn off the RF drive. |

Adjust the stepper tuner, if necessary to bring the detune frequency within range of the piezo control, typically 5 Hz | Show detune frequency and provide access to stepper motor controls |
Set piezo to "Integrator" mode and verify that the piezo tracks the detune frequency. | Buttons, plots |
