SiLC beam test - CERN SPS June 2008 - HIT MODE
4 Belle modules, 40MHz, HV=80V, 6 samples
trigger: 9 mm opening, TLUControl.exe -d 10 -a 12
telescope: 0sup., new firmware


Flex_Module has only 1 working APV - control bonds suffered during transportation

Position is approximately similar to KEK Nov 2007, however it appears like JP_module is flipped (up-down) w.r.t.

SAME AS PREVIOUS, BUT 0-SUP WITHOUT TELESCOPE

SiLC beam test - CERN SPS June 2008
HV=100V, xy "telescope"
8 modules, 40MHz, 6 samples, position centered
trigger: 9 mm opening, TLUControl.exe -d 10 -a 12
telescope: 0sup., new firmware


this is a run where modules 0,2,4,6 are in normal position, while modules 1,3,5,7 are rotated by 90 deg
(counterclockwise as seen by the beam) and flipped (back<->forth) in order to achieve the minimum spacing
(~10.3mm) between "corresponding" x and y planes.

SiLC beam test - CERN SPS June 2008
8 modules, HV=100V, 40MHz, 6 samples
trigger: 9 mm opening, TLUControl.exe -d 10 -a 12 (now for real)
telescope: zero supressed, new firmware

trigger is now correct (9 x 9 mm2 window)
