Conclusion
¥
¥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
