  To boost up the intensity of the uranium beam accelerated in the RIKEN RI Beam Factory (RIBF), a new 28GHz superconducting ECR ion source was constructed in 2008. The standalone commissioning of the ion source has started in early 2009. In order to control the ion source as a part of the RIBF accelerator complex, we introduced F3RP61-2L as IOCs and integrated them into the existing EPICS-based RIBF control system. F3RP61-2L is a new CPU module running Linux, which functions with the I/O modules of FA-M3 PLC on the PLC-bus. We have confirmed stable operation of EPICS on F3RP61-2L and found that the new IOC makes our control system simpler and easier to maintain. We will report the details of the control system of the new ion source and its integration into the whole RIBF control system.

  In the RIKEN RI beam factory project (RIBF), the accelerators are operated by the remote control system based on EPICS. On the other hand, for RIKEN Linear Accelerator (RILAC) of RIBF injector, the control system include not only EPICS-based controllers, but also handmade hard-wired controllers still in operation. It is required to replace the handmade hard-wired controllers with ones which can interface with the EPICS-based system on an ethernet interface. Since sequential logic control is not required on the controllers, costly Programmable Logic Controllers (PLCs) are not the appropriate candidate. To implement the low cost embedded controller in our system, we developed EPICS device support using asynDriver for PIC Network Interface Card (PICNIC*). The characteristics of PICNIC is Microchip PIC16F877 based embedded I/O controller with a network interface, a serial port, DIO 8ch and AI 4ch. It is suitable to use this controller for simple control, such as on-off control using electromagnetic relay. In April 2009, we started to adopt PICNIC as one of the remote controller in RILAC control system. In our contribution, we report this system and present the status in detail.
