Notes:
We have studied the possibility of using a superconducting microwave cavity resonator as an undulator. A small cavity, made from bulk niobium, has been built and tested. The cavity has an elliptical cross section in order to force a linearly polarized oscillation mode. The TE118 mode has been chosen as the most suitable. Fields of about 300 G have been obtained with 10 W of microwave power. Fields up to 1 kG are reachable with niobium of higher thermal conductivity and better surface treatment. A circular cross-section cavity, where left- or right-handed helical fields can be excited, is also briefly studied. If used as an undulator this cavity produces circularly polarized radiation which can be switched in short times from left- to right-handed polarization.
