BPM DAQ Software Structure VME Oscilloscope Cable Combiner BOX • New BPM DAQ System has been developed by a fast digital oscilloscope (Tektronix DPO7104) • All DAQ Systems have been replaced by New Systems • Performance of New DAQ System is enough for 50-Hz measurement. Summary Future Issue EPICS Record Design by VDCT • Development of IOC for beam operation • Development of Device Support including all Oscilloscope Functions • Realization of Synchronized Beam Orbit Measurement among all twenty-five DAQ Systems Result of Performance Test Introduction • Waveform acquisition speed of a fast digital oscilloscope was tested. (Remote/ Local test: Software is running on host computer/ oscilloscope) • Both test results is enough for our purpose (50-Hz measurement). • DAQ Rate by EPICS-IOC is also enough fast. • ・KEK Linac is a injector: • KEKB HER 8 Gev e-/ 3.5 Gev e+ • (Continuous injection Mode: CIM) • (2) KEKB LER 3.5 GeV e+ (CIM) • (3) PF 2.5 Gev e- (once/day) => Top-up • (4) PF-AR 3 GeV e- (twice/day) • ・For long-term stable beam operation: • Needs Beam Orbit and Energy Control We use about 100 of non-destructive BPMs for the orbit and energy feedback. ・Fast Beam-Mode Switch for KEKB CIM and PF Top-up => Needs Beam Position Measurement up to 50-Hz Fast BPM DAQ System Using Windows Oscilloscope-based EPICS IOCM.
