Injection System. Part II—Injection Optics

Abstract
The injection optical system, through which the 3.6‐Mev proton beam from the Van de Graaff accelerator enters the Cosmotron, consists primarily of a deflecting magnet and an electrostatic inflector in which the beam is deflected through angles of 25° and 30°, respectively. Viewing and detecting mechanisms are available for studies of alignment and ion optics. The ion optical properties of the system have been studied in detail; parameters have been chosen which yield an injected beam, parallel in the horizontal plane and diverging within an angle of 0.003 radian in the vertical plane.
