The Saskatchewan Accelerator Laboratory (SAL) was a linear accelerator facility on the University of Saskatchewan campus in Saskatoon, Saskatchewan, Canada. The facility was constructed in 1962 at a cost of $1.7M under the direction of Leon Katz.〔(Encyclopedia of Saskatchewan )〕 SAL was identified by the OECD as a National Large-Scale Facility.〔(OECD MEGASCIENCE FORUM WORKING GROUP on REMOVING OBSTACLES to INTERNATIONAL CO-OPERATION REPORT of the SUB-GROUP on LEGISLATIVE and ADMINISTRATIVE BARRIERS to MEGASCIENCE CO-OPERATION )〕 SAL provided support for radiology, chemistry and sub-atomic physics research. ==Beginnings: 1947–1961== Around 1947 members of the Department of Physics at the University of Saskatchewan decided to obtain a 25 MeV Betatron. The principal interest was in nuclear physics, but they were also interested In the possible therapeutic uses for the treatment of cancer,〔 and they obtained support from then-Saskatchewan Premier Tommy Douglas. Funding was obtained from the Atomic Energy Control Board , the National Research Council (NRC), the National Cancer Institute, local cancer societies and the University. The machine was installed in summer 1948 in a new building built in one angle of the existing Physics department, connected to the main building. It was manufactured by the Allis-Chalmers Company of Milwaukee, Wisconsin, and was very similar to the one being used at the time by Donald Kerst at the University of Illinois. The first cancer patient was treated on Mar. 29, 1949 starting the really first concerted clinical investigation of the usefulness of the betatron as a radiotherapeutic tool, with over 300 patients treated in 17 years of operation. The success of the program led to the installation of the world's first cobalt-60 source for radiotherapy at the University in 1951.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Saskatchewan Accelerator Laboratory」の詳細全文を読む スポンサード リンク
