Software choiceSoftware choice DATE (ALICE DAQ) not available in time UNIDAQ was an option but

No know-how in Geneva and no real interest in getting this know-how…

Readout ProcessReadout Process

Read out TDC and ADC works in Single- an/or Read out TDC and ADC works in Single- an/or Multi-Event ModeMulti-Event Mode

Readout of V1X90: up to ~20 MB/s, much less if the number of hits is small

Readout of 32 hits takes about 40 s

Readout of V792: limited to ~0.5 MB/s (Block Transfer is not working), good enough for BTF

Readout of 32 hits takes about 600 s

Readout loop is artificially slowed down to Readout loop is artificially slowed down to leave some CPU time for the monitoringleave some CPU time for the monitoring

-> Limited to 50 Hz

Should this limit be removed, the readout process can cope with up to 10 kHz (in Multi-Event Mode).

SummarySummary

BTF will use an homemade DAQ BTF will use an homemade DAQ softwaresoftware

DAQ software for BTF is readyDAQ software for BTF is ready Dedicated stand alone PC (single processor) Running Stable at 50 Hz

FEE electronics tests are under wayFEE electronics tests are under way There is hope to be ready with the Flash ADC Time over Threshold will not be ready

(Test can be done later without beam)
