The use of Bloch-type arrangements (induction principle) in ESR spectrometry is superior over conventional reflection arrangements. The advantage results from the better decoupling between transmitter and receiver, resulting in a higher stability of the overall system. A cylindrical cavity sustaining the dual degenerate TE modes showed best performance. With such cavities, decoupling-values of more than-110 dB are possible due to special devices. The spectrometer has an overall noise-figure of 8.3 dB, and 6 dB with an additional parametric amplifier. The decoupling device allows to couple circularly polarized waves into the cavity. Thus the sign of the spectroscopic splitting constant may be determined. [ABSTRACT FROM AUTHOR] |
