Review of Control Resources for J-PARC Accelerators | |
|
||
| J-PARC consists of three big accelerators : 181-MeV LINAC (now upgrading to 400-MeV), 3-GeV RCS (Rapid Cycle Synchrotron), and 30-GeV MR (Main Ring). Beam operation of LINAC started in November, 2006, followed by RCS in 2007, and by MR in 2008. Since 2009, J-PARC accelerators have been providing high-intensity proton beams to experimental facilities. In this report, we focused on three components; sever CPU for MR,control network, and disk system. Improvement, upgrade, and troublesduring 6-year operation will be reviewed. | ||

| WEPD47 | Low-cost EPICS Control Using Serial-LAN Module XPort | 81 |
|
||
|
In J-PARC MR (Main Ring), we are interested in a commercial product, XPort, a low-cost serial-LAN converter [1]. We have introduced it in two different cases. (1) Two RF-amplifiers with GPIB were introduced. We asked a company to add a XPort for remote control rather than GPIB. Serial messages of GPIB are transported to an EPICS IOC (I/O controller) over our control network. (2) We developed an electric circuit board with manual switches. An on-board FPGA chip has connections both to switches and to XPort pins. Status of switches can be read remotely as UDP messages through XPort. In both cases, messages are converted into EPICS-style records using AsyncDriver of EPICS. Implementation details and operational reports are given.
