DEVELOPMENTS OF THE TEUFEL INJECTOR RACETRACK MICROTRON

In this paper we report on developments of the 25 MeV racetrack microt ron (RTm) that will be the electron source for the second phase of the TEUFEL project, to generate radiation of 10 mum in a 2.5 cm period hy brid undulator. The theoretical understanding of this unconventional a zimuthally varying field type of RTM has been extended. A comparison o f analytically calculated orbit stability with that based on measured data will be presented; orbit calculations using measured field data s how the designed performance. Construction and tuning of the 1300 MHz, 2.2 MV microwave cavity have been completed, and signal level measure ments have been performed. The overall assembly of the microtron is ne aring completion. At present a vacuum pressure better than 5 x 10(-7) Torr is achieved.
