	The control system of the RIKEN RI-Beam Factory (RIBF) is based on the Experimental Physics and Industrial Control System (EPICS). To control magnet power supplies of cyclotrons and their beam transport lines, we are using VME and CAMAC as I/O Controllers (IOCs) depending on a kind of their interface boards. To control beam-diagnostic equipment and vacuum systems, small single-board computers mounted with Linux are used as IOCs. Other devices of cyclotrons like RF are controlled by PCs, which are independent systems from EPICS. These details will be reported. Furthermore, we will report about the RIBF beam interlock system using Melsec PLCs. We started beam commissioning of RIBF in July 2006 and succeeded in extracting uranium beam from the Superconducting Ring Cyclotron (SRC), which is the last of the multi-stage accelerators of the RIBF, on March 23, 2007.

	The PSI 590-MeV Cyclotron is already more than 30 years in operation. However, it still holds the world record in continuous beam power. There is an active experiment program being pursued, and new experiments are planned and being built. In addition, the beam intensity is being upgraded by 50%. The control system has been through several incremental upgrades. However, the new requirements and other developments at PSI (other accelerator facilities) force again an upgrade. This time the whole architecture of the system is to be changed. The controls hardware architecture will be changed and the underlying software will move to EPICS. All this has to happen without compromising the operation schedule. In the upgrade program we are planning to benefit from several new developments, both in-house and together with the community. The central technologies to be used will be presented. The issue of how to tackle the somewhat contradictory goals of upgrading on the fly will be discussed.

	The Tore Supra tokamak is the largest superconducting magnetic fusion facility. Its real time measurements and control system is designed to deal with continuous acquisition during the plasma discharge, fast acquisition (sampling frequency up to 4 GHz) and Real Time (RT) data processing. The simultaneous control of an increasing number of plasma parameters aiming at tokamak operations in a fully steady state regime makes fast acquisitions and RT data processing more and more de-manding. The Tore Supra Data Acquisition System (DAS) is based mainly on VME bus acquisition units using Lynx OS 3.1 as operating system. Some units are not able any more to handle in parallel the data flow rate (about 100ko/s increasing up to 6Mo/s during fast acquisition phase) and the RT processing. Furthermore, the time delay between two fast acquisition phases must be reduced to be able to catch fast plasma events. To cope with these needs, the data processing capability has been enhanced while preserving the existing acquisition system. A new DAS layer containing Linux-PC has been implemented. The link between the Lynx-OS layer and the Linux layer is ensured by a 100-Mbps Ethernet link.
WPPA27	Commissioning TRIUMF’S 2C Solid Target Facility Controls	controls, target, site, kaon	371

	The upgraded Beamline 2C Solid Target Facility was recently commissioned at TRIUMF. The original facility had run successfully producing radioisotopes since 1989. To improve reliability and maintainability, and to allow increased incident beam currents, an upgrade project was established. The basic functionality of the facility was retained but changes were made in a number of areas such as aspects of the control system and physical components in the beamline. The process and results of the commissioning, the reasons for upgrading, and the lessons learned are discussed.
