Hideyuki Sakamoto CM22, RAL 19/10/08 Tracker DAQ Hideyuki Sakamoto CM22, RAL 19/10/08

Tracker DAQ with EPICS By the last week, DAQ using DATE with EPICS has been checked to work correctly by the following procedures. Installation of DATE package Write test code Rebuild trigger logic Take data of C1-4 counters with DATE Check data Take data of C1-4 and 8 VLSBs Check data with that taken by EXCEL Replace code of AFE with EPICS one

R8 cosmic-ray test stand In R8, cosmic-ray test for Tracker#1 is running, and Tracker DAQ has been tested this time. Trigger counter (C3,4) Light-guides Light-guides Tracker#1 Cryo#1 Cryo#2 Lead block Trigger counter (C1,2)

Notes on v6.28 Few codes were needed to fix to start readout process. Path to readout exe. file is changed as below. ${DATE_SITE}/hostname (@v6.09)  ${DATE_SITE}/aloneldc (@6.28)

Data taking Latest run(#323) is currently taking data, now it has 2k events. Trigger rate is about 0.016 Hz (1 event/min)

Decoding There 3 equipments to record data V792N: ADC of trigger counters (4 channels) AFE: Temp/Heater of 4 cassettes (32 channels) VLSBSlave: ADC/TDC of 8 VLSBs (4096 channels)
