1. Booster ring progress - Key Commissioning Milestone Achieved

(Contact: les.dallin@lightsource.ca)

The second of three phases of commissioning has been successfully completed. The Booster ring is now fully operational. The design goals for energy (2.9 billion electron volts) and current (20 milli-amps) were fully met, and the electron beam was so well aligned that magnets for correcting the beam's orbit did not have to be used, though they will be used in future to refine the alignment.

On Saturday September 14, a 20 mA, 2.9 GeV beam was extracted from the booster to the BTS dump. The beam current was measured on the FCT, ICT and the dump and extraction efficiency was determined to be very nearly 100%. Estimates of the beam size indicate a beam emittance of less than 1. mm-mrad. Since this met the booster design goals an efficiency run was made the next day. The booster was then run continuously for 6.5 hours delivering a beam of over 15 mA in the BTS line. The next major step will be to inject and store the electron beam in the storage ring, a milestone expected to be achieved in early 2003.

2. 5th Annual CLS Users' Meeting- November 15- 16, 2002

(Contact: stephen.urquhart@lightsource.ca)

Registration is now open for the 5th Annual Users Meeting, on November 15-16, 2002 at the University of Saskatchewan. This meeting, organized by the Users' Advisory Committee of the Canadian Light Source, will be a great opportunity to learn about the progress of the Canadian Light Source, present your recent synchrotron work or ideas for future work, meet fellow users, and rub elbows with our new director. The following Workshops will also be held in association with the meeting:

Materials Science with Synchrotron Radiation

3. Beamlines Update

(Contact: emil.hallin@cls.usask.ca)

In the last month, significant progress has been made on all photon beamlines, frontends and insertion devices at the CLS. The first shipment of magnet blocks for one of our insertion devices has arrived. Construction will soon begin on a magnet measurement lab, a user machine shop and the endstation for the facility diagnostic beamline. A Request for Quote (RFQ) for the High Resolution Far IR beamline spectrometer has been issued, and a similar RFQ for the mid IR spectromicroscopy beamline will follow shortly. Procurement of the major optical components for the soft x-ray beamlines (VLS PGM, High Resolution SGM and Soft X-ray spectromicroscopy) is almost complete. When the final drawings are ready a Request for Quote for the photon beamline frontends will be issued. Several vendors have bid on the protein crystallography beamline design build package and an award will be made soon. The preliminary design report for the XAFS beamline (with excellent powder diffraction and microprobe capability) has been completed, and a design build package based on this Preliminary Design Report will be issued soon. So far, all of the awarded contracts are within budget and delivery has been at or ahead of schedule.

Work is progressing on determining what the phase II package of beamlines should include. A committee of the CLSI Board of Directors has been struck to help guide the user community and the CLS through this process. An open, consultative process has been established to ensure that this package reflects the needs of the Canadian SR research community and that the package be created in a timely fashion.

4. Storage Ring Progress

(Contact: dan.lowe@lightsource.ca)

The cryogenic plant is being commissioned this month. The liquid nitrogen and helium storage tanks have been filled, and vacuum jacketed distribution lines are being installed for the beamlines' liquid nitrogen supply. The cables and the pedestals for the quadrupole and sextupole magnets have arrived. The magnet power supplies and the girders for magnet supports have started arriving. The dipole pedestals are expected later this month and the quadrupole and sextupole magnets should arrive in mid-October. Vacuum chambers are also being received now and the ion pumps and vacuum valves have arrived. Installation of the initial components (pedestals and main piping) is expected to begin before the end of October.

5. Health Safety and Environment Department

(Contact: mohamed.benmerrouche@lightsource.ca)

Radiological characterization of Phase I beam commissioning which included the Linear Accelerator has been completed; the final report has been submitted to the Canadian Nuclear Safety Commission (CNSC) and it has been deemed satisfactory. Comprehensive radiological measurements were undertaken during Phase II beam commissioning, which included the Booster ring, and the data is being analysed. An application for approval of Phase III beam commissioning, which will include the storage ring and the beamlines, has already been submitted to the CNSC. The public hearing on this application will be held on December 12, 2002 in Ottawa.

The CNSC licensing project officer confirmed verification and validation of one of the integral elements of the CLS personnel safety system, the Access Control Interlock System for the Storage Ring, on a visit to the site last September 28.
