Considerations for Buying a Pre-Owned Linear Accelerator ...

Many radiation oncology centers often struggle with the idea of new vs. used equipment. However, it's important to note that unless a linear accelerator was installed in the past week, it's already a "used machine." This means that virtually every linear accelerator system in operation today is already used.

How do linear motors work? A simple introduction

Jul 15, 2019· The basic principle behind the linear motor was discovered in 1895, but practical devices were not developed until 1947. During the 1950s, British electrical engineer Eric Laithwaite (1921–1997) started to consider whether linear motors could be used in electric weaving machines. Laithwaite's research at Imperial College, London attracted ...

THE DESIGN OF LINEAR ACCELERATORS

THE DESIGN OF LINEAR ACCELERATORS The linear accelerator is a device for accelerating electrons or positively charged particles to a high energy, by the application of an alternating rather than a direct field, and in a straight line, rather than in an orbit curved by a magnetic field as in the cyclotron, betatron, or synchrotron.
