A milestone in the fruitful collaboration between STFC and the Paul Scherrer Institute (PSI) in Switzerland was achieved this week with the delivery to PSI, just in time for Christmas, of the undulator for the SwissFEL laser heater system. This is a system to prepare the electron beam before it enters the hard X-ray Free-Electron Laser (FEL) to ensure optimum FEL performance. The undulator was designed and constructed by ASTeC and the Technology Department. The magnetic and mechanical measurements, which demonstrated that the undulator performance comfortably met the specification, were done in the Magnet Measurement Laboratory within the Engineering Technology Centre. The undulator now waits at SwissFEL ready for installation in the New Year.
