A racetrack microtron as a source for a free electron laser is being constructed. It will accelerate electrons up to 25 MeV to provide 10 ?m radiation in a hybrid undulator with a periodicity distance of 25 mm. The aim is to accelerate 100 A bunches of 30 ps pulse length at 81.25 MHz. This frequency is chosen to minimize cavity loading, by avoiding simultaneous presence of more than one bunch in the microtron cavity. The self-focusing longitudinal action of the microtron assures a small energy… Expand

The injector microtron for the TEUFEL infrared laser
Progress is reported on a 25 MeV injector racetrack microtron for a 10 ?m radiation free electron laser (TEUFEL project). The accelerator exhibits transverse focusing in 180° inhomogeneous two-sectorExpand
Electron beam focusing in a racetrack microtron by means of rotated two-sector dipole magnets
Abstract We present an unconventional method of electron beam focusing in a racetrack microtron (RTM). The RTM bending magnets have a two-sector shape (valley and hill) and are slightly rotated inExpand
Performance of the SASE amplifier of the TEU-FEL project
The free-electron laser of the TEU-FEL project of the University of Twente will be driven by a photoinjector followed by a racetrack microtron. The injector, which is now under construction, willExpand
Developments of the TEUFEL injector racetrack microtron
In this paper we report on developments of the 25 MeV racetrack microtron (RTM) that will be the electron source for the second phase of the TEUFEL project, to generate radiation of 10 µm in a 2.5 cmExpand
