===Before The CLS ===

The first accelerator research programs at the University of Saskatchewan was established in [[1948]], when Canada's first [[betatron]] (a 25 MeV machine) was constructed in the Physics Building. Based on this early success in 1951 the world's first non-commercial [[cobalt-60]] therapy unit for the treatment of cancer was constructed on campus and then in [[1961]] construction of the [[Saskatchewan Accelerator Laboratory]] (SAL) started and was completed in [[1964]]. In [[1999]] SAL operations were discontinued and the accelerator used as an injector for the CLS. In addition to the CLS the University continues to operate a small [[Tokamak]] as part of the [[Plasma Physics Laboratory (Saskatchewan)|Plasma Physics Laboratory]].

Prior to the CLS, Canada (through the [[University of Western Ontario]]) operated several beamlines at the similar [[Synchrotron Radiation Center]] (SRC), at the [[University of Wisconsin–Madison]], in [[Stoughton, Wisconsin]].

===The CLS Project===

On March 31, 1999 The [[Canada Foundation for Innovation]] provided partial funding for the construction of the CLS facility. The remaining matching funds from Saskatchewan, Ontario, Alberta, Saskatoon and industry would follow between 1999 and 2001. The CLS is one of the largest science project in Canadian history, and represents an unprecedented level of cooperation between the [[Government of Canada]], the governments of [[Saskatchewan]], [[Ontario]] and [[Alberta]], the City of [[Saskatoon]], universities across [[Canada]] and industry.

On 21 September 1999 The CLS project was officially launched. On 21 February 2001 the CLS building expansion was completed. The SAL linac was refurbished and placed back into service on 13 September while the Booster Ring (BR1) and Storage Ring (SR1) were still under construction. First turn was achieved in the BR1 ring in July 2002 with BR1 fully commissioned by September 2002. First turn in the SR1 ring was achieved on September 2003, with first light in December. In April 2004 SR1 achieved 100 mA.

===Operation===

On 15 July 2004 CLS received regulatory approval from the [[Canadian Nuclear Safety Commission|CNSC]] for normal operation. The grand opening occurred in October 2004. On May 19, 2005 [[Elizabeth II of the United Kingdom|Her Majesty Queen Elizabeth II]] ([[Queen of Canada]]) and [[Prince Philip, Duke of Edinburgh|His Royal Highness The Duke of Edinburgh]] visited the CLS. A few days later on May 27 the first experiment by an outside user was conducted.

===Phase II Beamlines ===

On March 8, 2004 CLS received partial funding ($18M) from the Canadian Foundation for Innovation for the phase II beamline expansion project.[http://www.lightsource.ca/media/CFI.php] The phase II beamlines include:

* Biomedical Imaging and Therapy (BMIT), $17M;

* Soft X-Ray Beamline for Microcharacterization of Materials (SXRMB), $4M;

Line 58:

===Phase III Beamlines ===

On November 27, 2006, the Canadian Foundation for Innovation awarded a further $25.8 million for the initial funding of a phase III expansion project, consisting of five new beamlines. Phase III will include:

* The Brockhouse X-ray Diffraction and Scattering Sector (BXDS), 2 beamlines;

===Linac===

Originally part of the SAL facility, the [[linear accelerator]] was refurbished and modified in 1999-2000 to become the injector for the CLS. Originally intended to operate at 180  Hz, the linac was modified for 1  Hz operation. The linac is followed by an Energy Compression System and then a 70 m transfer line (LTB1) that delivers the beam to the booster ring (BR1).

===Booster Ring (BR1)===

Beam is delivered to the booster at 200-250 MeV where it is accelerated to a final energy of 2.9 GeV. The Booster ring was manufactured by Danfysik with final installation and assembly done at the CLSI. The booster ring uses an RF frequency of 500  MHz. The beam is extracted from the booster and transferred through the BTS line and into the SR1 ring.

===Storage Ring (SR1)===

===Isotope Linac===

In 2011 the Canadian Light Source received $12 Million Canadian in funding to purchase and operate a four meter long linear accelerator for the production and study of isotopes used in nuclear medicine. <ref>[http://www2.canada.com/saskatoonstarphoenix/news/story.html?id=dc9ad528-db75-476a-ba19-57969d473a78 Isotopes deal for CLS Jeremy Warren, The StarPhoenix Published: Tuesday, January 25, 2011 ]</ref>
