Mechanical Engineering of a 75-Kev Proton Injector for the Low Energy Demonstration Accelerator
Proceedings of the 1997 Particle Accelerator Conference (Cat No97CH36167)（2002）
Abstract
A dc injector capable of 75-keV, 110-mA proton beam operation is under development for the Low Energy Demonstration Accelerator (LEDA) project at Los Alamos. The injector uses a de microwave proton source which has demonstrated 98% beam availability while operating at design parameters. A high-voltage isolation transformer is avoided by locating all ion source power supplies and controls at ground potential. The low-energy beam transport system (LEBT) uses two solenoid focusing and two steering magnets for beam matching and centroid control at the RFQ matchpoint. This paper will discuss proton source microwave window design, H-2 gas flow control, vacuum considerations, LEBT design, and an iris for beam current control.
