Generation of a saw-tooth bunch at AWA

摘要

The current profile of a charged particle bunch regulates the self-generated fields that play a critical role in several applications: wakefield acceleration, radiation generation, and control over the bunch's quality. The recently developed exchange-based method of temporal manipulation provides direct control over the longitudinal phase space via transverse manipulation followed by a transverse-to-longitudinal exchange. This new method is capable of generating higher quality temporal distributions compared with previous coupling-based methods. In this paper, we introduce the principle of the exchange-based temporal shaping method, experimental demonstrations of temporal distributions generated, and describe application experiments planned at the Argonne Wakefield Accelerator facility.
