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 probably unaware of the Heils' work.

Linear accelerator diagram

The main features of radio-frequency linear accelerators are introduced, reviewing the different types of accelerating structures and presenting the main characteristics aspects of linac beam dynamics. 1 Introduction Using linear accelerator particle accelerator (LINAC) technology, Liang et al. administered a total of 12 Gy (85% isodose line) in two fractions to seven patients with MTLE. 49 All patients in their cohort had poor seizure control at 2 years, including two patients who experienced a doubling of their seizure frequency. linear accelerator field but the designs have been taken over by Brown Boveri Corporation, who in- tend to produce a virtually identical range of ma- chines. A block schematic diagram of the accelera- tor is given in Fig. 1 showing the principal supply and control paths.
