Beam Synchronous DAQ (BSDAQ)

Babak Kalantari (PSI); MRF workshop, Prague, Eli Beamlines, 05.05.2014

• on-demand BSDAQ (in production)• runs only for specified number of pulses (seconds

or minutes)

• continuous BSDAQ (under design)• runs always at the background over a specified

history window up to current time (e.g., last 2 days)
