INTRODUCTION TO RF LINEAR ACCELERATORS Mario Weiss CERN, Geneva, Switzerland ABSTRACT The basic features of RF linear accelerators are described. The concept of the 'loaded cavity', essential for the synchronism wave-particle, is introduced, and formulae describing the action of elec­ tromagnetic fields on the beam are given.

It is evacuated with a vacuum pump so that the accelerated particles will not collide with air molecules. The length will vary with the application.
