continued bump study.
after scanning the collimater with the slits open (see last shift summary) we measured the BQM rates with no bumps, and the slits at their optimum position. rates were:
T=60, L=19, B=17, R=9 (lifetime=11min at 88 mA)
(see config files for this weekend's runs for slit positions)
then did a horizontal bump to +1.5 mm, found new optimized slit positions, and BQM rates were:
T=178, L=79, B=43, R=21 (lifetime = 9min at 73 mA)
(please see config files for slit positions)
took empty target data at this position for remainder of shift. runs 2942-2946 are crunching. next: do same exercize for vertical bump.
