¥
¥CLAS DAQ performance was
improved significantly: event rate increased from 3kHz to 8kHz, data rate from 17MB/s to
at least 50MB/s, dead time remains below 15%
¥Event rate will reach 10kHz
after pipeline TDCs readout speed will be increased by using 2eVME protocol - CAEN is working on new firmware
¥Free-running front-end and
multiprocessing back-end were two key technologies used in upgrade
¥Total project cost: hardware
about $600K, manpower about 3 years
¥DAQ upgrade allows much more
efficient running of upcoming CLAS experiments
¥Big step to meet CLAS12
requirements
