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.
