Let's meet Monday March 13th at 11am in the MCC conference room to organize 4-LLRF installation and commissioning. Please come prepared to speak to relevant items below, and/or invite those whom should attend. We'll end the meeting with a ~firm plan that Steve can post to the SAD calendar.
Topics
- Plan for 4-LLRF installation
- Software controls and screen readiness
- FSD implementation and testing
- First connection to lasers, manual testing 249/499
- Remote HLLAP control of laser frequency
- Repair bunch length
- Schedule for beam operations
- Beam tests: chopper, bunch length, energy spread
- Dry run for Fall 4-beam ops
- Running during the summer
- Installation of final system
- Any other topic you'd like to discuss
Summary
- 4-LLRF Installation
- Tomasz' readiness/plans presentation media:4Laser_LLRF_March_ready.ppt
- Estimate is one week to install 4-LLRF system beginning start of SAD (nominally March 23)
- FSD interface monitors 35/70 MHz; thresholds set in EPICS, Rama working w/ Brad/PSS for FSD node
- Existing 3-LLRF hardware remains as-is, new 4-LLRF installed near chopper/buncher
- 4-LLRF application recycles existing EPICS channel names, Rama/Scott will meet before SAD to clarify 3-LLRF vs. 4-LLRF code
- Once 4-LLRF is up/running and tested OK will coordinate a) Michele's HLAPP test, b) connecting laser ON again
- Bench test isolation between RF channels >45 dB
- Tomasz needs to know how precisely power levels should be set for 10 dBm
- 4-Beam Testing
- 4-Beam setup of injector to FC2 is vehicle to test system
- Reza would like spectrum analyzer measurement of existing 3-LLRF vs. new 4-LLRF documented
- Curt/Reza will continue troubleshooting bunch length system in preparation of beam setup
- Arne would like a dwell run of ~shifts to demonstrate stability
- Ops will plan to generally support DAY's to FC2 (and look for a Swing/Owl crew for stability test)
