RF superconductivity. Proceedings, 5th Workshop, Hamburg, Germany, August 19-23, 1991. Vol. 1, 2

The Fifth Workshop on Radiofrequency Superconductivity was held at DESY from August 19 to 23, 1991, two years after the Fourth Workshop organized at KEK. The workshop was attended by 152 persons from 8 countries. The workshop was split up into laboratory talks (one day), review talks (two mornings) and poster contributions (two afternoons). Two days of the workshop were reserved for TESLA, succeeding the First International TESLA Workshop held at Cornell, July 1990. We would like to thank all authors for delivery of camera ready manuscripts and G. Enderlein and our conference secretary K. Lando for preparation of the proceedings
