DAQ rate/Dead time• Generate dummy trigger at 100 MHz• Input dummy trigger to V977 I/O reg.

– Veto subsequent triggers by busy-out from V977• Measure DAQ rate by detecting interrupt signal from

V977– Event loop:

• Clear busy• Enable interrupt• Wait for interrupt• Count-up event number

• Measured DAQ rate = 14 kHz => Dead time = 71 sec

Comments

• Stand-alone DAQ program has been employed for the test.• Device driver by CAEN does not implement read/write functions.• Use CAENVMElib in the program

– Library for the driver to manage VME masterV2718, distributed by CAEN

• Function CAENVME_IRQEnable returns “Unknown Error” – CAENVMElib– Source code for this library is not distributed.

• Seems no problem for DAQ (for now).– It should be fixed. (also, dead time becomes smaller?)– Jean-Sebastien suggests that we need to contact CAEN software team.

Data taking is not working

which should be implemented!
