||The activities of INFN Genoa in the
field of the RF Superconductivity are shifting toward the application
of Superconducting Cavities to a Gravitational Wave detector operating
in the 4-10 KHz frequency range of the Gravitational Wave spectrum. The
first prototype of the detector cavity, built at CERN under an
INFN-CERN collaboration agreement, is under test in Genoa. The group is
planning for the next three years the construction of a Demonstrator
Detector based on the already existing INFN-CERN cavity. As a side
activity the Genoa Group is developing a small RD project to check the
achievable limits (field and Quality Factor) for Pipe Cooled cavities.
If proven successful, pipe cooling will greatly reduce the acoustic
coupling in the GW detector. Pipe cooling can also be useful in
reducing the helium inventory, (and cryo-system complexity) in standard
Superconducting Cavity applications. The Genoa group is still
refining and updating the Twtraj Code for the simulation of electronic
discharges (resonant or not) in accelerating cavities.
