Comments: Run 5609 30uA, production style. Dithering disabled. Compton interaction region optimization. 16:39 - started run 5609 16:50 - beam gone for 10-15 minutes to fix Hall B problem. 17:10 - MCC called to say that there would be no beam for at least 20 min more. 17:39 - 30 uA of beam back in Hall A 17:55 - Compton interaction point tuning done 18:05 - MCC has viewers in, beam back in 10-15 minutes. 18:13 - 30 uA of beam back in Hall A 19:15 - request new raster setting 9x12 19:40 - lots of beam trips in the last 1/2 hour. 20:00 - request new raster setting 6x12 20:20 - scanner run 21:30 - go to 40 muA 21:45 - jt valve open so that we can go higher in beam current 22:10 - go to 50muA 23:00 - go to 60muA after having raised the trip limit on the ion chamber in the left dump 23:30 increase fan speed to 65Hz 23:45 increase fan speed to 70Hz Summary of runs ------------------ 5607 - boiling check 5608 - global check 5609 - global check, dithering off 5610 - pedestal run 5611 - global check, dithering off for Compton interaction point setup 5612 - production style, dithering on again. 5613 - raster 9x12 3k good pairs 5614 - raster 9x12 10k good pairs 5615 - raster 6x12 10k good pairs 5616-5621 scanner runs 5622 - 40muA HV tune 5623 - 40muA 5624 - 50muA HV tune 5625 - 50muA 5626 - 53muA HV tune 5627 - 60muA HV tune 5628 - 60muA - 60Hz fan speed 5629 - 60muA - 65Hz fan speed 5630 - 60muA - 70Hz fan speed 5631 - 60muA - 73Hz fan speed
