| Popis: | A three pole superconducting wiggler with six racetrack NbTi coils kept together by iron yokes has been constructed and tested. The high field wiggler will provide photons of high intensity, high photon flux, and high degree of circular polarization with a beam life time of 10 h. The authors give an overview of the training procedure of the wet layer impregnated magnet. The tests indicated an obvious improvement of the critical current by training, although an excessive number of quenches were required. Quench analysis and some other cryogenics are also included in the discussion. Measurements are compared to the calculated values. > |
