Abstract
A pulsed electron paramagnetic resonance spectrometer comprises: a microwave excitation generating unit for generating at least one microwave pulse; a microwave conducting unit comprising a resonant cavity and a microwave transmission line for transmitting microwaves, wherein the microwave transmission line is connected between the microwave excitation generating unit and the resonant cavity, and the resonant cavity is for placing a sample; a cryostat and magnet unit comprising a cryostat that performs ultra-low temperature cooling for the microwave resonant cavity, the microwave transmission line being disposed to pass through the cryostat and connected to the resonant cavity; the cryostat and magnet unit further comprises a magnet that provides a resonance test magnetic field around the sample, the resonant cavity being disposed in a room temperature gap of the magnet. The device of the present disclosure characteristics in ultra-low sample temperature (0.1 Kelvin) and is fully functional and easy to operate.
