	The vacuum requirement of the RISP heavy ion accel-erator facility has been derived that meets the beam loss requirement and the vacuum system design is carried out using the 3D Molflow+ code verifying the vacuum re-quirement. We used realistic outgassing values of the materials of the vacuum chambers and beam pipes. We are designing detailed vacuum system specification and configuration including pumps, gate valves, and vacuum gauges along with the interlock system and differential pumping stations.

	The Rare Isotope Science Project (RISP) Control System is comprised of ethernet-based devices and equipment. Control system is based on Experimental Physics and Industrial Control System (EPICS) Framework, known as a distributed control system through network. So, we need a way for integrating ethernet-based devices into EPICS Framework. Most of these devices support Simple Network Management Protocol (SNMP). SNMP is based on the manager and agent model and it is similar to EPICS Channel Access (CA) protocol. Therefore, SNMP helps to develop a unified network-based control system with EPICS. In this paper, we will show the network device monitoring system RAON customized SNMP integration into EPICS.

	RISP control system uses the EPICS real time distributed control system, which is software framework for stable operation of the accelerator. The output signal from all machines and devices must be archived by EPICS framework, and optimized signal archiver system is needed for each accelerator facility. Signal archiver method using the EPICS framework has three significant ways. First is the classic channel archiver using the file base method and the second is the RDB archiver using the relational database. But classic channel archiver has a problem that the index file containing information of data block corresponding PV data mismatch with real data. Also, there is a problem in the performance of file I/O in RDB archiver. SLAC has developed archiver appliance utility to resolve these problems, and the usage of archiver appliance in EPICS community has gradually increased. RISP choose the archiver appliance to also signal archiver solution. However, archiver appliance is not optimized for our RISP heavy-ion accelerator control system. Thus, we will develop the customized signal archiver system for RISP heavy-ion accelerator control system.
