ADVANCES IN CRYOMODULE DESIGN AND NEW APPROCHES

This paper presents the experience gained designing, constructing and commissioning the TESLA Test Facility (TTF) cryomodules, from the prototype to the most recent version that fulfills the TESLA requirements. The new solutions adopted in terms of radiation shields and cavity fixtures will be particularly discussed due to their impact on cost and performance. Based on this experience some ideas are presented which should be applied to the cryomodule design for the new generation of high current proton linacs.
