Abstract:

This paper describes a scheme for trapping the injected beam in a modified betatron accelerator using a localized inductive electric field pulse generated by a charged coaxial pulseline. The average canonical angular momentum Po is not conserved in this scheme. Numerical simulations demonstrate trapping over a wide range of operating parameters. A 0.84-0, 45-ns water dielectric pulseline has been built for testing the trapping concept. The pulseline is switched using triggered vacuum surface switches. By crowbarring the pulseline, its output is limited to a single bipolar pulse that has a - 22 ns rise time.
