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. [1] SAL was identified by the OECD as a National Large-Scale Facility. [2]
On April 2, 1999, these divisions split to become Varian Semiconductor, Varian, Inc., and Varian Medical Systems. [12] [13] In August 2020, Siemens Healthineers announced plans to acquire Varian Medical Systems in an all-stock deal valued at $16.4 billion. [14] [15] The deal was approved and completed on 15 April 2021. [16]
Varian Associates was one of the first high-tech companies in Silicon Valley.It was founded in 1948 by Russell H. and Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the klystron, the first vacuum tube which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.
Varian was spun off from Varian Associates in 1999 and was purchased by Agilent Technologies in May 2010 for $1.5 billion, or $52 per share. [ 2 ] Varian Inc. had its corporate headquarters in Palo Alto , California , and offices in Australia, the Benelux countries, Brazil, Canada, China, Germany, France, Italy, Japan, Korea, Russia, Sweden ...
[60] [61] After the merger Varian will continue to operate as an independent company and will retain its headquarters along with its 10,000 employees. [ 62 ] [ 63 ] In August 2024, Siemens Healthineers bought the diagnostic arm of Advanced Accelerator Applications that specialises in producing radioactive chemicals used for cancer scan for more ...
The Varians went on to found Varian Associates to commercialize the technology (for example, to make small linear accelerators to generate photons for external beam radiation therapy). Their work was preceded by the description of velocity modulation by A. Arsenjewa-Heil and Oskar Heil (wife and husband) in 1935, though the Varians were ...
A linear particle accelerator (often shortened to linac) is a type of particle accelerator that accelerates charged subatomic particles or ions to a high speed by subjecting them to a series of oscillating electric potentials along a linear beamline.
Therefore, it was decided in 1963 to build a new linear accelerator, which would later be called Linac 2. This new machine would provide protons with the same energy as before (50 MeV), but with higher beam currents of up to 150 mA and a longer pulse duration of 200 μs. [5] Construction of Linac 2 started in December 1973 and was completed in ...
