first days of RHIC Run 6 beam commissioning. With positive results, the possibility of implementing operational
feedback control of tune and coupling during beam commissioning will be considered. After beam commissioning,
chromaticity feedback will be explored as a part of the accelerator physics experimental program. We will summarize
the results of these investigations, and discuss possible implications of these results for LHC commissioning.
ISAC II RF Controls - Status and Commissioning
The rf control system for the 20 ISAC II su-

perconducting cavities is a hybrid analogue/
digital design which has undergone several
iterations in the course of its development. In the current design, the cavity operates in a self-excited feedback loop,
while phase locked loops are used to achieve frequency and phase stability. One digital signal processor provides
amplitude and phase regulation, while a second is used for mechanical cavity tuning control. The most recent
version has been updated to incorporate newer hardware and software technology, as well as to allow for improved
manufacturability and diagnostics. Operating firmware and software can be updated remotely, if the need arises and
system security permits. This paper describes the RF control system, outlines the status of the system, and details the
commissioning experience gained in operating this system with the first four-cavity cryomodule.

One of TRIUMF’s isotope production facilities,
the 2C Solid Target Facility (STF), is being
upgraded. This installation is located on
a primary beamline of TRIUMF’s 500 MeV
Cyclotron. As a part of this upgrade project, the STF Control System is also being revised. Changes to the STF are
meant to enhance reliability and maintainability. The existing STF controls have run very reliably and have provided
the required functionality but were implemented in part using different technology to that used for the majority of the
cyclotron’s Central Control System. The new hardware and software controls should provide a simpler, more easily
maintained configuration. Additional goals are to modify the user interface to more closely resemble the interface
used for running the 500 MeV Cyclotron, to enhance the event annunciation, and to increase the number of parameters
logged.

is scheduled for April 2006 and 10 BL operation for the end of 2006. This paper will describe the technical
solution choosen for the control systems of accelerators and beamlines, and will give the status of the deployment.
On the hardware side, the SOLEIL Controls team has implemented an industrial approach using PLCs, standard
Motion Controlers and CPCI Systems. The details of our technical choices and architectures will be described in
this paper. On the software side, the SOLEIL Controls team has worked closely with ESRF’s one on the TANGO
framework since 2002. A quick tour on the TANGO software components used for SOLEIL Controls will be detailed.
On the supervision layer, SOLEIL has choosen Java as the core technology, using javabeans components provided
