A cryomodule built at Fermilab for the free-electron laser FLASH at DESY arrived at the lab on Tuesday after travelling by road, air, road again and finally crane to its new home. It will now be dressed with couplers and then put into the FLASH linear accelerator during a major upgrade this autumn. The ‘third harmonic’ module is one of Fermilab’s contributions to the TESLA Technology Collaboration TTC that built FLASH as a test facility for superconducting radiofrequency technology.
