Design and Performance of a New Multifunction X-band EPR Spectrometer

doi:10.11938/cjmr20212965

Abstract

Abstract:

A new multifunction X-band electron paramagnetic resonance (EPR) spectrometer is designed and produced, which is equipped with a new operation system based on the EPR control and readout system (CRS). The new continuous-wave (cw) dual-mode resonator and the dielectric resonators for respectively the pulsed EPR and transient EPR (trEPR) are designed purposely. The adoption of CRS system improves significantly the integration and expandability. The spectrometer is equipped with cryogen-free EPR variable temperature system with a range of 6~300 K. Thereafter, three typical samples are used to demonstrate the elegant design of the spectrometer by the cw dual-mode EPR, pulsed EPR and trEPR experiments. Perspectively, this design herein will be a criterion or option of the new generation of EPR spectrometer.

Key words: EPR spectrometer, pulsed EPR, transient EPR, dual-mode EPR, control and readout system
