Electron clouds limit the performance of many major accelerators and storage rings. Significant quantities of electrons result when halo ions are lost to beam tubes, generating gas which can be ionized and ion-induced electrons that can multiply and

Applications of Electron Linear Induction Accelerators

Autor: Glen Westenskow, Yu-Jiuan Chen

Publikováno v: Induction Accelerators ISBN: 9783642139161

Linear Induction Accelerators (LIAs) can readily produce intense electron beams. For example, the ATA accelerator produced a 500 GW beam and the LIU-30 a 4 TW beam (see Chap. 2). Since the induction accelerator concept was proposed in the late 1950s

Plasma simulations are often rendered challenging by the disparity of scales in time and in space which must be resolved. When these disparities are in distinctive zones of the simulation domain, a method which has proven to be effective in other are

RTA beam dynamics experiments: Limiting cumulative transverse instability growth in a linear periodic system

Autor: Glen Westenskow, Tim Houck, S. Lidia

Publikováno v: AIP Conference Proceedings.

A critical issue for a Two-Beam accelerator based upon extended relativistic klystrons is controlling the cumulative dipole instability growth. We describe a theoretical scheme to reduce the growth from an exponential to a more manageable linear rate
