Issues
- double peak in bpm X appears since run 6161, continues to most recent run
- raw asym of url goes up to huge value
- 3 (12:00 - 15:00) hours of hall C spin dance
- LQ2 tripped off at 19:07
- it looks like the bpm X double peak just gone after we return to production run 6176, though we still don't know why there comes the double peak and how it goes away?
- for run 6176-6179, MCC can't deliver beam larger than 120 uA, so we just run at 120 uA
