  Common Object Request Broker Architecture (CORBA) based control system has
been utilized for the first phase of RIKEN-RI Beam Factory (RIBF) [1] at the
developing stage. Software sharing with Jozef Stefan Institute (JSI) in
Slovenia via CORBA/JavaBeans has been successfully demonstrated. Accelerator
Beans (Abeans) [2] components developed in JDK1.2.2 have been ported to RIKEN's
CORBA server. The second phase of the RIBF project is named "Multi-Use
Experimental Storage rings" (MUSES) project, which includes an accumulator
cooler ring (ACR) and collider rings. Due to the much larger number of
controlled objects and more stringent timing requirement than the first-phase
project, we contemplate using recently established real-time (RT) CORBA
specification [3]. Summary of our efforts to test RT-CORBA with the existing
JaveBeans components and other related subjects are described in this paper.
