Query: Control System of the Bepcii   Recently the Chinese Academy of Sciences has chosen BEPCII as the future
development of the BEPC, i.e. upgrade of both the machine and detector. The
luminosity of the machine is expected to increase to 1.0x1033cm-2s-1. The
project will be started at the beginning of 2002 and finished with in 3-4
years. The BEPC control system was built in 1987 and upgraded in 1994.
According to the design of the BEPCII, a double ring schema will be adopted and
a number of new devices will be added in the system. The existing control
system has to be upgraded. The BEPCII will be distributed architecture and
developed by EPICS. We are going to apply the standard hardware interfaces and
mature technologies in the system. A number of VME IOCs will be added in the
system and the feildbus, PLCs will be used as device control for some kind of
equipment. We will keep the existing system in use, such as CAMAC modules and
PC front-ends, and merge it into EPICS system. Recently the development of the
prototype is in progress. This paper will describe the system design and
development issues.
