Varian Medical Systems is an American radiation oncology treatments and software maker based in Palo Alto, California. Their medical devices include linear accelerators (LINACs) and software for treating cancer and other medical conditions with radiotherapy , radiosurgery , proton therapy , and brachytherapy .
The design of a linac depends on the type of particle that is being accelerated: electrons, protons or ions. Linacs range in size from a cathode-ray tube (which is a type of linac) to the 3.2-kilometre-long (2.0 mi) linac at the SLAC National Accelerator Laboratory in Menlo Park, California.
Linac 3, also referred to as the Lead Linac [16] was constructed inside the former tunnel of Linac 1 and got commissioned in the summer of 1994 (construction started October 1992).

The upgrade took just over two years, being commissioned in October 2005 [3] [4] and tested for 4 months. In Autumn 2006 it was used to re-commission the PS to handle ions, and then again a year later it was used to re-commission the SPS. However, it wasn't until November 2010, five years later, that it successfully carried out its primary role ...
