*************************************************************************** 1- New CLS Scientific Advisory Committee Appointed (Contact: bill.thomlinson@lightsource.ca) Dear Colleague: We have been very successful in putting together the first CLS Scientific Advisory Committee. We initially received approximately 70 names from the community and Board of Directors, and with CLS research directors and management, reduced the list to 13. The final decision on whom to contact was mine. An initial list of candidates was approved by the Board of Directors, with several additional suggestions approved by the Chairman of the Board. Of those contacted, only 2 were unable to serve. The Users Advisory Committee nominated 5 Canadian scientists for our consideration and Board approval. We selected the 12th committee member from those recommendations. Our decisions were based on the following considerations:
We believe that we have assembled an outstanding SAC, and the enthusiastic response from those we contacted is confirmation of the high regard held in the community for the CLS and its future. We are also very pleased that Dr. Bruce Gaulin has agreed to be the chairperson of the SAC.
The first meeting of the SAC will be organized for the second quarter of
this year. *************************************************************************** 2- Research Director Posting – CLS Scientific Leader (Contact: bill.thomlinson@lightsource.ca) In co-operation with the University of Saskatchewan, the CLS has begun the recruitment process to hire a Research Director to lead scientific programs at the facility. Consideration of applications will begin March 1, 2004 and will continue until a suitable candidate is found. Interested applicants are encouraged to contact Bill Thomlinson, Executive Director. For more information please go to: http://www.lightsource.ca/careers/ *************************************************************************** 3- Notes from the UAC- Election Results- New members (Contact: aanderso@stfx.ca) I'm pleased to announce four new members have been elected to represent the users of the Canadian Light Source in the Users' Advisory Committee:
As the new Chair of the Users' Advisory Committee, I extend an invitation to all users to contact the members of the UAC with any concerns or questions. I look forward to coordinating the efforts of the UAC in support of science at our facility. It is indeed a privilege to serve as Chair of the UAC on the year of the official opening of the CLS. I would like to thank outgoing Chair Tom Tiedje for his excellent leadership and successful efforts during 2003. Our thanks also to the departing members - Jeanette See (Alcan); Dennis Klug (SIMS/NRC), Emil Hallin (CLS) and Stephen Urquhart (UofS). 2004 will be a busy year and an important year for the CLS as it begins operations. We will be meeting regularly to address your needs, and we will also soon begin to plan the next Annual Users' Meeting- whether you have attended previous user events, or are planning to attend for the first time, we welcome your suggestions. Sincerely, *************************************************************************** 4- Storage Ring Commissioning Progress (Contact: les.dallin@lightsource.ca) Storage ring commissioning is progressing well. At present we can accumulate a current of 25 milliamps (mA) in less than four minutes. At this current the lifetime of the beam is approaching one hour. Higher currents will be possible once the beam orbit is further corrected and the vacuum condition is improved. Orbit correction is expected to be complete by the end of March and the vacuum continues to improve as we continually run current in the storage ring. Basic machine parameters have been measured and indicate we are operating near the nominal machine settings. With these measurements machine modeling is possible and the model indicates a horizontal emmitance of 27 nanometre-radians (nm-rad.) (Emmitance is an indication of beam size.) Our objective for September 2004 is to store 100 mA with lifetimes of several hours and to achieve our design emmitance of 18 nm-rad. In the meantime, the present beam will be adequate for commissioning the beamlines expected to come online in the next few months once optimization of the orbit through the straight sections is complete. *************************************************************************** 5- Experimental Facilities Update (Contact:emil.hallin@lightsource.ca) Infrared:

Bob was a Research Technologist and Work Coordinator in the CLS Electronics Shop and had been with us since September 1, 1999. He had worked at the Saskatchewan Accelerator Laboratory from 1990-1993 and then spent a number of years working in the North West Territories before coming back to the CLS. He also had a very distinguished career in the Canadian Armed Forces for almost 25 years, as a radar technician, in several posts across Canada. Bob was laid-back, easy going and enjoyed life to the fullest. His happiest times were spent with his family and friends. He was an outdoorsman, and enjoyed camping, canoeing, fishing, ice-fishing, hiking, and snowmobiling. More often than not, there would be a kid or two in tow during these activities. Bob also thoroughly enjoyed teaching students at the CLS. He was recently particularly proud when last summer the students helping him on the booster ring lock-up system got it right- the first time! Also, his “debates” with John Stampe on all things automotive, in the coffee room, were a particular treat for those of us listening! We will miss him dearly. *************************************************************************** 7- Invitation to attend IUCR 2004, August 18- 21- Saskatoon (Contact: John.Tse@nrc-cnrc.gc.ca) Dear Colleague: This is to invite your participation to present an oral or poster contribution at the 2004 International Union of Crystallography - High Pressure Commission Workshop to be held at the newly commissioned Canadian Light Source on the campus of University of Saskatoon, Saskatchewan, Canada during 18th-21st August, 2004. This international workshop will focus on recent advances in high pressure sciences and techniques. The workshop will consist of a series of Keynote lectures highlighting the state-of-the-art of High Pressure Research and invited presentations covering New Materials and Chemistry, Mineral and Geophysics, Liquids, Single Crystals Metals and Alloys, Theory and Computation and the latest of techniques development. We encourage young scientists and graduate students to attend this conference. A small bursary will be available to support the travel of eligible attendances. We hope that you will be able to attend the workshop and contribute a paper. Please let us know the likelihood (very likely, likely, unlikely, very unlikely) of your participation which would greatly help the planning of the workshop. Details of the programme and invited speakers will be posted on: www.lightsource.ca/iucr2004 Yours sincerely, *************************************************************************** 8- NRC in the spotlight: “The Canadian Light Source" - February 2004 Please click here to read the new NRC article on the CLS: http://www.nrc-cnrc.gc.ca/highlights/0402cls_e.html *************************************************************************** 9- Live Internet Lectures from Berkeley- Soft X-Rays and Extreme Ultraviolet Radiation (Contact: attwood@eecs.berkeley.edu) This course will explore modern developments in the physics and applications of soft x-rays and extreme ultraviolet radiation. Following a brief review of atomic physics and relevant absorption edges, the lectures consider electromagnetic radiation at short wavelengths, including dipole radiation, scattering and refractive index using a semi classical atomic model. Subject matter will include the generation of x-rays with synchrotron radiation, laser-plasma sources, high harmonic generation, x-ray/EUV lasers, and black body radiation. Concepts of spatial and temporal coherence will be described.

A group of graduate students and their supervisor, Dr. Graeme Spiers, from Laurentian University drove 32 hours (each way) to visit the synchrotron on January 27th to learn about how they can use it in their different areas of science: botany, earth sciences; biology and chemistry. CLSI scientists, including Ning Chen, Tom Kotzer and De-Tong Jiang hosted the students. The group thoroughly enjoyed the visit and gave us the following feedback: David Marshall (Botanist): “Thirty-Two hours in the back of a van
and I would do it all over again. The system could do neat things with my
tree rings?” See the group at: http://www.lightsource.ca/photos/events.php *************************************************************************** 11- Visit the CLSI Booth at Globe 2004, March 31- April 2- Vancouver (Contact: sandra.ribeiro@lightsource.ca) We will be at booth #1209 at the premier environmental conference in Canada.
