The SUPRATECH research platform is dedicated to R&D on superconducting accelerating cavities intended to constitute future powerful accelerators of high-energy particles. It provides all the equipment necessary to prepare, condition, assemble and test a superconductive cavity and its associated components, with in particular: an ISO4 clean room, a laboratory for surface treatment by chemical etching, an oven for thermal treatment under vacuum, an installation producing superfluid liquid helium, a calibration station for cryogenic thermometers, as well as various experimental zones equipped with RF power sources and several cryostats also allowing generic tests at cryogenic temperatures.

The platform consists of:

    • an etching laboratory, which the cavity surfaces treated in acidic baths, in order to eliminate all defects likely to generate electron spurious emissions.
    • an ISO4 cleanroom, this high technology equipment (covering 80 m2, 50m2 of which are class10) is the essential link for the cleaning and assembly of superconducting cavities.
    • an assembly hall, dedicated to the integration of the cryostats,
    • two experimental halls, equipped with vertical and horizontal cryostats to test and RF validate the cavities.

To optimize the use of these infrastructures, the platform is equipped with : 

    • RF power sources operating at 88 MHz, 350 MHz and 700 MHz frequencies,
    • a station including a helium liquefier and its associated recovery and compression system ; this very expensive gas, the release into the atmosphere of which would be anti ecological and which is here carefully recycled.
    • a 400 kW cooling system (HF sources)
