Title :
Injection and transport studies on the UNM cusp array transport experiment
Abstract :
Summary form only given. High-current beam injection and transport have been conducted in the Cusp Array Transport Experiment (CATE), a steel-core recirculating induction accelerator with strong magnetic focusing for high-current beam confinement. Previous problems with beam transport were solved, and almost ideal beam confinement has been observed in a 360° section of the machine. A low-emittance, space-charge dominated beam (280 A, 550 kV) traveled through the full optical system with low loss, small emittance growth, and no profile distortion. The system consisted of 40 periodic focusing cells with transitions to and from a straight section. Also observed was beam translation in the E×B inflector, in good agreement with theoretical predictions
