===The road to the CLS: 1972-1999===

[[image:SAL LINAC.jpg|thumb|left|
Canadian interest in [[synchrotron radiation]] dates from 1972, when Bill McGowan of the [[University of Western Ontario]] (UWO) organised a workshop on its uses. At that time there were no users of synchrotron radiation in Canada. In 1973 McGowan submitted an unsuccessful proposal to the [[National Research Council (Canada)| National Research Council]] (NRC) for a feasibility study on a possible synchrotron lightsource in Canada. In 1975 a proposal to build a dedicated synchrotron lightsource in Canada was submitted to NRC. This was also unsuccessful. In 1977 [[G. Michael Bancroft|Mike Bancroft]], also of UWO, submitted a proposal to NRC to build a Canadian [[beamline]], as the Canadian Synchrotron Radiation Facility (CSRF), at the existing [[Synchrotron Radiation Center]] at the [[University of Wisconsin-Madison]],USA, and in 1978 newly-created [[Natural Sciences and Engineering Research Council| NSERC]] awarded capital funding. CSRF, owned and operated by NRC, grew from the initial beamline to a total of three by 1998.

At the start of the project, all staff members with the former SAL were transferred into a new non-profit corporation, Canadian
Light Source Inc., CLSI, which had primary responsibility for the technical design, construction and operation of the facility. As a separate corporation from the University, CLSI had the legal and organizational freedom suitable for this responsibility. UMA, an experienced [[engineering]] firm, now part of [[AECOM]], with extensive experience managing large technical and civil construction projects, was hired as [[project management|project managers]].<ref name="CLSI">{{cite web | url=http://accelconf.web.cern.ch/accelconf/e04/papers/weilh04.pdf|title=Industrial involvement in the construction of synchrotron lightsources| date=2004 | format=PDF | accessdate=2012-28-07}}</ref>

The initial funding included seven beamlines, referred to as Phase I, which covered the full spectral range: two [[infrared]] beamlines, three soft X-ray beamlines and two hard X-ray beamlines.<ref name="Bancroft" /> Further beamlines were built in two further phases, II (7 beamlines) and III (5 beamlines), announced in 2004 and 2006 respectively. Most of these were funded through applications to CFI by individual universities including UWO, the [[University of British Columbia]] and [[Guelph University]] <ref name="progress" />

==Notable Science==

An international team led by [[University of Calgary]] professor Ken Ng solved the detailed structure of [[RNA polymerase]] using X-ray crystallography at the CLS. This enyme replicates itself as the [[Norwalk virus]] spreads through the body, and has has been linked to other [[supervirus|superviruses]] such as [[hepatitis C]], [[West Nile virus]] and the [[common cold]]. Its duplication is responsible for the onset of such viruses.<ref name="Norwalk">{{cite web |url=http://www.canada.com/calgaryherald/news/city/story.html?id=865bf07a-f32f-4a35-b970-ed3f26068e72 |title=U of C researcher cracks Norwalk code| date=20 March 2008 | accessdate=2012-27-07}}</ref>

In April 2012 the CLS was "visited" remotely by Governor General [[David Johnston]]. He was visitng the [[LNLS]] synchrotron in [[Brazil]], during a live link-up, by video chat and remote control software, between the two facilities.<ref>{{cite web|url= http://www.globalsaskatoon.com/saskatoon+synchrotron+operated+via+brazil/6442630904/story.html|title=Saskatoon synchrotron operated via Brazil |date=29 April 2012 |accessdate=2012-07-15}}</ref>

==Education program==
[[image:Students on the beamline.jpg|thumb|left|
The CLS has an education program - "Students on the Beamlines" - funded by NSERC Promoscience. This outreach program for science allows high school students to fully experience the work of a scientist, in addition to having the chance to use the CLS beamlines.
