Abstract

The cryostat designed for the superconducting cavities of the Tesla Test Facility (TTF) is quite a complex structure with strict requirements on the alignment of the different components at the LHe temperature. A system able to measure on-line misalignments on the full length of the cryostat module (12 meters long) during cool down and operation procedures seems a very useful tool in order to verify structural analysis computation. A microstrip based system using a stretched wire has been designed for this purpose in our laboratory. DESY will provide the stretching system for the wire and the support system for the position transducers. In this paper we will present and discuss the design based on warm and cold tests on a prototype
