by the TANGO toolkit within an industrial SCADA (GlobalScreen). These tools and components for Graphical User
Interface development will be presented. At last, an overview of the deployment of these systems on our installation
will conclude this document.
Control Applications for SOLEIL Commissioning and Operation
Synchrotron SOLEIL, the French third generation
light source being commissioned in
2006, is the first facility using TANGO as a
full control system. Control applications for

operation and Beam Physics Dynamics have being developed using two major tools: the Matlab Middle Layer adapted
from ALS and Spear3, and GlobalSCREEN, commercial SCADA software. Both tools are fully interfaced with the
TANGO control system. In this paper, a sketch of the software architecture is shown. Then Storage Ring applications
developed in house are presented. Finally configuration and database related applications (archiving, snapshot) are
briefly described.
The New Control System for the Future Low-emittance Light Source PETRA 3 at DESY
At DESY, the existing high-energy physics
booster synchrotron PETRA 2 will be trans- R. Bacher (DESY)
formed into a 3rd-generation light source
(PETRA 3) after the final shutdowm of HERA operation mid 2007. In addition, the technical systems and components
of the pre-accelerators LINAC 2 and DESY 2 will be improved. Within the scope of this project, the control
system and the front-end electronics will be upgraded. Key elements of the conceptual design are TINE (Threefold
Integrated Network Environment) as integrating software bus to provide efficient data communication mechanisms
and support services, control room applications based on the thick-client model for optimum visualization and performance
and Java as programming language to ensure platform independence, server-side control APIs in various
languages to allow choice of the language that is best suited for the control task to be done, a common device interface
for generic access to various field buses, and CANopen as interface standard for device electronics to ensure longterm
maintenance. The complete conceptual design and the current project status will be presented.
Digital Master Oscillator for the ISIS Synchrotron
Rutherford Appleton Laboratories in Oxfordshire
is home to an 800MeV synchrotron C.W. Appelbee, M.G. Glover (CCLRC/RAL/ISIS)
particle accelerator called ISIS. Its main function
is to direct a beam of protons into a heavy metal target to produce neutrons for scientists to analyse condensed
matter. A second harmonic system is being developed to upgrade the beam current from 200uA to 300uA in order
to drive a second target station. This is being achieved by the inclusion of four second harmonic cavities to increase
the width of the RF bucket. In the past the six fundamental cavities were driven by an analogue master oscillator but
the extra cavities will bring more difficultly in the phasing of the system. This could be more easily and precisely
controlled by embedding a Direct Digital Synthesis core into an FPGA chip as the heart of a new digital Master
Oscillator. This paper describes the initial research and feasibility of such a system for the setting up, phasing and
