  4. Installation Accelerators SOLEIL is a third generation Synchrotron radiation Source, located at the Plateau de Saclay near Paris. The 354 m circumference storage ring is mainly composed of 32 (+1) dipoles, 160 quadrupoles, 120 sextupoles, 2 RF cryomodules, ~ 200 vacuum chambers, 6 injection equipments; 12 beamline front-ends and 4 insertion devices (initially). The 157 m circumference Booster comprises 36 dipoles, 44 quadrupoles, 28 sextupoles, 1 RF cavity and 8 injection/extraction equipment Storage Ring Sextupoles (220/280 Kg) Linac Quadrupoles (900/1200 Kg) Dipoles (3,5T) Long Girder (4,8m–7,8T) Booster Cell with 3 girders

  7. 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 organization

  8. Commissioning organization • General planning • Detailed protocol for each session • Electronic logbook • One report of each session • A commissioning team • People working 3 x 8h; 7d/7; (example : 7h am-3h pm-11h pm-7h am) • Overlap of 1/2 an hour between 2 successive team • On-call and shift people. • weekly meeting for commissioning team and for each encountered problem

  11. First turns (May 14, 2006) successive turns detected by the FCT successive turns detected by the FCT • Quadrupoles and CorrectorsON, Sextupoles and RFOFF. After correction of first turn trajectory and closing the first turn. • SextupolesON and RF OFF.

  12. 10 mm vertical aperture chambers When the beam could be circulated for the first time in the Storage Ringit goes several times through the 10 mm small vertical aperture of the 10 insertion device chambers distributed along the ring without any correction.

  13. Closed Orbit with All correctors OFF H rms=3.1mm max=6.40mm V rms=0.41mm max=1.44mm => Excellent magnet alignment (BPM offsets included after BBA)

  14. Current and Integrated Dose, year 2006 maximum current of 300mA possible with only one cryomodule RF was reached after only 30A.h of integrated current dose

  15. Beam position stability (with SOFB) on 2 straight sections during a 8 hours beamline shift. DX ~ 3 µm , DZ ~ 1 µm mA mm injection Beam current (Source point Positions) X (PX1) X (CASSIOPEE) Z (PX1) Z (CASSIOPEE)

  16. STORAGE RING COMMISSIONING

  17. 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) Results and innovations

  18. RF System Innovations Solid State RF Amplifiers4 x 190 kW power amplifiers 1st cryomodule inside SR tunnel Each of the four cavities is powered by a 190 kW solid state amplifier consisting in a combination of four “towers” producing about 50 kW each.

  19. 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.

Balance - sheet In year 2007, From January to July, 93.8% of the 1426 total hours of beam were delivered to beam lines In year 2006, over the 2084 operating hours The availability of the beam represented 83.5 % of total time, with 11.2 % of time of breakdowns and 5.3 % of time of injection, preparation of manipulations, or interventions

  33. Planned Objectives L 3096 hours Beam Lines 3 000 hours Beam Lines M 1800 hours Machine 1 000 hours Machine . 3864 hours Shutdown L M planned of operation of the year 2007

  34. 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 2007. 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.
