The proposed Resonant Wake Field Transformer (KWT) Col- lider is a colinear Iwo-beam system with a hollow driver beam A train of many hollow beam bunchrz, accelerated hy a mpercon- ducting cw structure, excites the transformer cavity tesonanlly. Due to an impedance transformation, a high acceleration gradi- ent is gsnerated on the axis of the transformer cavily. After the main central beam has pansed Ihe Iranaformet, the remaining energy is recuperated into the next superconducting driver RPC- tion by a second train of hollow beam bunches. The longitudinal multibunch dynamite of the hollow beam in the driver and the transformer cavity is studied Results concerning the int,erde- pendcncics of t,hc cssrn&l design parn~m&rs ate presented.
