FINAL CLEANING AND ASSEMBLY

For high gradients at high Q-values in superconducting (s.c.) cavities the final cleaning and assembly procedures are of well-known importance. Starting from the experiences with the standard processes used for 1.3 GHz nine-cell cavities of the TESLA Test Facility at DESY, various methods of cleaning, assembly, drying and pumping are presented. Improvements of the established procedures as well as some alternative approaches are discussed.
