North - Holland The injector microtron for the TEUFEL infrared laser
نویسنده
چکیده
Progress is reported on a 25 MeV injector racetrack microtron for a 10 wm radiation free electron laser (TEUFEL project). The accelerator exhibits transverse focusing in 180° inhomogeneous two-sector dipole magnets which are slightly rotated with respect to each other in the bending plane . This provides closed orbits, isochronism and a large transverse acceptance. Details on this unconventional microtron focusing system will be given . An analytical treatment, based on conformal mapping, of the field near pole boundaries and at the hill-valley boundaries in the microtron dipole is compared with Poisson calculated results and with field measurements . The design of a model accelerating cavity is presented together with field measurements based on the perturbation ball method.

In order to obtain high gain m a free electron laser a high-quality electron beam with high peak current is required . It is well-known that a microtron is able to produce a high-quality beam having low etntttance and small energy spread (1%0). Because a circular nucrotron has a linuted high-current capability a race-track design is adopted for providing flexibility, better beam quality and of ...

The Laboratório do Acelerador Linear (LAL) of the Physics Institute of the University of São Paulo (IFUSP) is building a 31 MeV continuous wave (cw) racetrack microtron [1][2]. This two-stage microtron comprises a 1.8 MeV injector linac, a five-turn microtron booster that increases the energy to 4.9 MeV, and the main microtron, which delivers a 31 MeV cw electron beam after 28 turns. The inject...
