Commissioning & Operation of SOLEIL Jean-Claude Besson – Trieste – WAO 2007 Commissioning organization A commissioning team of about 20 persons composed of the machine physics group and people coming from different areas was constituted in the early stage. They shared their experience and their knowledge in the preparation of the different phases of the commissioning and in the analysis of the results. This organization allowed a fast progress of the commissioning (round clock operation) and different ways to see and solve the encountered problems.

Commissioning & Operation of SOLEIL Jean-Claude Besson – Trieste – WAO 2007 Results and innovations We had no problems with innovations This good result clearly demonstrates the beneficial effect of the NEG coating on the aluminium chamber. This technology was never seen before on accelerators at such extensive use. 2 other innovations concern the RF system: the dedicated Superconducting cavities (1st cryomodule enable alone operation up to 300 mA, a 2nd cryomodule which is being build by ACCEL will enable to reach 500 mA) and the solid state RF amplifiers that are used for the first time in the world for such high power. Except few transistor failures, the system is very stable. Specific and innovative electromagnetic insertion devices were developed for VUV beamlines: –3 HU256 (10eV to 1000eV) 3.6 meter long –1 HU640 (5eV to 40eV) 10 meter long Extended spectral range :from UV (5 eV) up to hard X-Rays (15 KeV)

Commissioning & Operation of SOLEIL Jean-Claude Besson – Trieste – WAO 2007 During the shifts, within the operation group, 8 operators take their turns every 8 hours in order to ensure the presence of one of them 24h/24h and 7 days a week in the control room. This operator is assisted by 1 or 2 part-time operators (like ESRF) who come for majority from SOLEIL source division. Before being ready to work in control room, they get training by the "machine physicists" on the general operation of the machine. During shutdown, permanence in control room is ensured by an operator during the normal schedule. Apart from the operation of the machine, the operators are implied in the result analysis and in the developments (software and equipment) enabling a better understanding and operation of the installation.

Commissioning & Operation of SOLEIL Jean-Claude Besson – Trieste – WAO 2007 CONCLUSION AND MAIN OBJECTIVES FOR EARLY 2008 The SOLEIL accelerator complex is now fully operational. The transition from the commissioning phase to the operation phase went smoothly, thanks to: –The strong implication and participation of the operation group during the commissioning of the machine. –Significant efforts from the machine physics groups and from the different groups in charge of equipment to transfer their knowledge to the operation crew. –The machine availability already reached 93.8 % over the 1521 hours of beam time delivered to the beamlines during the first 7 months of We are now aiming at increasing further this availability. The next objectives set-up for 2008 are: –500mA operation (with second cryomodule) –Preparation for top-up operation –Single bunch and 8 bunches operation –Secure beam stability with many insertion devices –Increase beam availability.
