Study of pc-based console for the J-PARC control system

The control system for the J-PARC accelerator complex has been under development using the EPICS toolkit. Though we need X-window consoles with the EPICSbased control system, the only choice is to use the PC platform, because no X-terminals are presently available on commercial markets. In addition, we need Java consoles, since we expect more use of Java in future commissioning studies. We used PCs with two operating systems (Linux and Windows), in beam-commissioning studies of the proton linac during 2002-2004. Based on this experience, we discuss the realistic perspective of a PC-based console system suitable for the J-PARC project.
