NETWORK-BASED WAVEFORM MONITOR FOR THE J-PARC ACCELERATOR COMPLEX

In an accelerator control, the remote observation of waveforms is very important. We have been interested in a commercial product, WE7000 of Yokogawa, as a lowcost network-based oscilloscope. As a part of development studies of an EPICS-based control system for the J-PARC accelerator complex, we have developed three EPICS drivers for the WE7000 modules: a 100 MS/s oscilloscope (WE7111), a 100 kS/s digitizer (WE7271), and a 10MHz function generator (WE7121). This report describes the functions and performances of the EPICS drivers of the WE modules, and experimental applications of them during beam-commissioning studies at the KEK 60-MeV proton linac.
