Abstract
A modified cup-like TW accelerating structure for TESLA Positron Pre-Accele rator (PPA) is designed by optimizing the structure geometry and by changin g the iris thickness cell by cell in a section. This structure has high shu nt-impedance and a large iris radius to meet with the requirements of high gradient and large transverse acceptance. The beam dynamics in the structur e with the optimum solenoid focus held are studied. A satisfactory positron beam transmission and the beam performance at the PPA output have been obt ained. In this paper the accelerating structure design is described in deta il and the results are presented. (C) 2000 Elsevier Science B.V. All rights reserved.
