  • Probehead insert for EPR apparatus
    Patent number: 12270874
    Abstract: An insert for an EPR probehead is disclosed. The insert comprises a directional coupler and an amplifier. The directional coupler receives microwave power from a source at a first port and transfers a portion of the received microwave power to a second port for transmission to a sample space. The directional coupler is also arranged to receive a microwave signal from the sample space at the second port and to pass the majority of the received microwave signal to a third port. The amplifier has an input and an output; the input is arranged to receive the microwave signal from the third port of the directional coupler and to produce an amplified version of the received microwave signal at the output for transmission to a detector.
