First full-size ILC cryomodule assembled at KEK’s STF test facility

The image shows the assembly work of the cold mass for an ILC cryomodule in the superconducting rf test facility (STF) at KEK. Since the STF tunnel has a limitation for the size of the components to bring in, only half-size modules could be assembled before. STF now is equipped with new assembly facility in the tunnel, and this will be the first full-size ILC cryomodule to be assembled at KEK. This cryomodule will have a beam position monitor and a superconducting quadruple magnet in the centre, planned to be completed in December. In January, scientists will connect another half-size cryomodule, and start the cooling test in June.
