Poor Livetime Issue for MUID BLT standalone

Poor Livetime Issue for MUID BLT standalone. BLT Electronics at Rack Room. From IR. Standalone w/ BLT Trigger Rate Test. Only ¼ of MUID HV were powered on. We turned on one quadrant HV at a time. We anticipated to see x2 or x4 trigger rate increase as two or 4 quadrant’s HV powered on.

  3. Standalone w/ BLT Trigger Rate Test Only ¼ of MUID HV were powered on We turned on one quadrant HV at a time. We anticipated to see x2 or x4 trigger rate increase as two or 4 quadrant’s HV powered on. However the trigger rate was saturated <300Hz and doesn’t increase.

  4. Standalone w/ BLT Trigger Rate Test Only ¼ of MUID HV were powered on We know we are sending in reasonably proportional trigger rates to GTM. See scaler rate column in above table. Somehow trigger signals were lost in GTM. We counted “SYNC LL1” with the scaler as well and it was consistent with number of triggers in standalone.

  5. BLT Signals plugged into GTM input a) b) +2.5V • We checked BLT signal shape to GTM input. We tried both TTL and inverse TTL as above, but resulting large loss of the trigger at GTM was same. In addition, we tried • Wider the width 150ns, 200ns, 300ns of above signal a) • but they didn’t affect on trigger loss.
