ENDOR cavity for electron spin echo experiments
Abstract:
A microwave cavity is described for performing ENDOR measurements in conjunction with electron spin echo experiments. The frequency of the cavity is approximately 9.4 GHz and the Q value approximately 80. Both of these parameters can be changed by making small alterations in the design. The radio-frequency magnetic field is confined to a small volume in order to minimize inductance and maximize the field strength obtainable for a given current. Direct measurements show the field in the sample to be approximately 11 G/A of coil current in a typical case. This corresponds to a field approximately 8 G in the rotating frame per ampere of coil current.
