Abstract

The design study of two possible configurations for the ELFA linac are presented. The first one is a multicell SLAC-type structure scaled down to 1300 MHz, the operating frequency of ELFA. The second one is a multicell standing wave structure similar to the one foreseen for the Tesla project. The effect of the input and output couplers on the beam dynamics in the Travelling Wave is carefully studied by computing the fields of the whole structure (including the couplers) by using the HFSS electromagnetic solver developed by Hewlett-Packard. Last the computed dispersion relation for the model structure is compared with the measured one of a prototype structure
