    keyword=Raised LUMI voltages

    Run 2421 was a short production run during which I raised the LUMI voltages so that they are mostly around 40-42k ADC counts.  We were at 30uA while I was doing this, so I wanted to leave a little overhead in case the beam current rises (ie, if Hall C goes off or following a spot move).
    
    	Old HV	New HV	(these are setpoints, not readback values)
    Ch 0	425	450
       1	850	850
       2	475	495
       3 	425	450
       4	480	510
       5	400	430
       6	425	450
       7	425	430
       8	525	555
       9	625	635
    
    All values negative of course.  I left BLUMI2 at 850 since it's already so much higher in voltage than the others -- it's around 22k ADC counts.
