At the J-PARC Main Ring (MR), we have used virtual-machine environment extensively in our accelerator control. In 2011, we developed a virtual-IOC, an EPICS In/Out Controller running on a virtual machine [1]. Now in 2013, about 20 virtual-IOCs are used in daily MR operation. In the summer of 2012, we updated our operating system from Scientific Linux 4 (SL4) to Scientific Linux 6 (SL6). In the SL6, KVM virtual-machine environment is supported as a default service. This fact encouraged us to port basic control services (ldap, dhcp, tftp, rdb, achiver, etc.) to multiple virtual machines. Each virtual machine has one service. Virtual machines are running on a few (not many) physical machines. This scheme enables easier maintenance of control services than before. In this paper, our experiences using virtual machines during J-PARC MR operation will be reported.

In J-PARC Main Ring (MR), a control system for new skew quadrupole magnets has been constructed. This system is based on EPICS　(Experimental Physics and Industrial Control System). The system comprises a YOKOGAWA F3RP61-2L (a PLC controller running Linux), a function generator (Tektronix AFG3000), and a commercial bipolar-DC Amplifier. The function generator is controlled using VXI-11 protocol over Ethernet, and the amplifier is connected to PLC I/O modules with hardwire. Both devices are controlled by the F3RP61-2L. The Function Generator produces a ramp waveform at each machine cycle of 2.48 seconds. The DC amplifire drives the magnet. The control system for skew quadrupole magnets was developed in 2012, and has been in opeation since January, 2013.
