1. Booster ring progress - 2.9 GeV achieved

In the first week of July, a beam of relativistic electrons was successfully transferred from the refurbished linear accelerator to the booster ring. It was then transported around the 100-metre circumference booster ring with substantial current for several millions of turns. The current was measured and detected on a monitor (click here for an image: http://www.lightsource.ca/media/analyze_screen.php)

On August 13th, electron energy reached 2.9 GeV with about 6.5 mA of current. This is well on the way to our design goal of 10 mA at 2.9 GeV. As well, enhanced by the use of orbit correctors, 12 mA was stored at the injection energy of 250 MeV. Next, orbit correctors will be ramped to improve the amount of current that survives to high energies.

2. Notes from the UAC - Annual Users' Meeting Poster Session

(Contact: stephen.urquhart@lightsource.ca)

Preparations are gearing up for this year's Annual Users' Meeting, scheduled for November 15-16th, 2002 at the University of Saskatchewan. We will end the Saturday afternoon session of this meeting with a poster session in the stunning Geology Atrium -- a great opportunity for users to "rub elbows" and talk synchrotron science with each other and with the new director!

The Canadian Institute for Synchrotron Radiation (www.cisr.ca) is again sponsoring an award for the best student poster at the Annual Users' Meeting. This award consists of a $1,000 travel support for the student to present their work at a scientific conference. Last year's winner, Lisa Croll of McMaster University, recently gave an oral presentation of her work at the 2002 X-ray Microscopy in Grenoble, France.

Please see http://www.lightsource.ca/uac/ for registration and program information.

3. Saskatchewan Synchrotron Institute launched

(Contact: dennis.johnson@lightsource.ca)

Saskatchewan businesses and researchers now have a new institute dedicated to advancing the many benefits from the Canadian Light Source (CLS) synchrotron, under construction at the University of Saskatchewan. At a press conference on July 24, Premier Lorne Calvert and Secretary of State (Western Economic Diversification) (Indian Affairs and Northern Development) Stephen Owen announced matching contributions of $500,000 to establish the Saskatchewan Synchrotron Institute (SSI). The SSI will be a "virtual" institute. Temporarily located at the CLS, it will ensure Saskatchewan maximizes the benefits from its investment in Canada's only synchrotron by co-ordinating and delivering research and supplier strategies and programs.

For more information please go to: http://www.gov.sk.ca/newsrel/2002/07/24-601.html or go to the SSI website http://www.sasksync.ca/.

4. PX Beamline Design Team Meeting. Saskatoon June 22, 2002

(Contact: pawel.grochulski@lightsource.ca)

Conclusions of the meeting:

Members of the Team have agreed to support Jim Britten's application for the multipurpose diffraction beamline, but they would like to apply for the second ID PX beamline.
Since CCD detector technology is still developing very fast the order for it should be placed a year from now.
Essentially the second PX beamline has been approved by the FAC and it is up to us to argue which design will best serve the user community. It is CLS policy that all straights will be chicaned with another ID. In that case the consensus was that we would prefer the second ID in our straight also be dedicated to PX, rather than share with another community. If this chicaning doesn't work well, we will know from experiences at the APS and ESRF. In such a case we can use a BM source for the second PX beamline. The Team would have to apply with the CLS to CFI for the second PX beamline. Deadline is February 2003. We should stress the science and the demanding important structures in the CFI application first (innovation) and the genomics/high throughput second. Structural genomics are being done mainly on bending magnets in the US. SGU's are being used for high impact structures.
The next meeting of the Beamline Design Team shall include discussion on the beamline control. People from Elder's group as well experts from outside shall be present. For more information please go to: ftp://transfer.lightsource.ca/XFG/CMCF/meetings/meeting_2002_Jun.htm.

5. Far Infrared Beamline has spectrometer funded

(Contact: tim.may@lightsource.ca)

An NSERC Major Installation Grant award of $310,000 for a far infrared (FIR) spectrometer has been granted to a team of 14 University researchers from across the country, headed by Robert McKellar, a Principal Research Officer at the National Research Council's Steacie Institute for Molecular Sciences. CLS will provide $220,000 from the infrared beamline budget to obtain the spectrometer at a total cost of $530,000. This spectrometer enables the study of structure and internal dynamics of gas phase molecules by means of high-resolution spectroscopy at wavelengths around 0.1 mm. Molecular spectroscopy provides the key to identifying molecules in remote sources by means of their spectral "fingerprints" and gives detailed information on intermolecular forces. Their research targets molecules of chemical, astrophysical, and atmospheric interest. Measurements in the FIR region are more difficult than shorter (infrared) or longer (microwave) wavelengths due to the weakness of ordinary thermal sources and a lack of practical FIR lasers. The CLS synchrotron will provide FIR light that is more than 100 times brighter than other sources.

For more information contact Tim May (tim.may@lightsource.ca) or Robert McKellar (Robert.Mckellar@nrc.ca) who is also the Principal investigator on the Far Infrared beamline team.
