Short summary
The developed probe head, which is a combination of the bimodal resonator operating in transmission mode and the low-noise amplifier, led to at least a 2-fold improvement in the sensitivity of the electron paramagnetic resonance spectrometer independent of sample temperature. The probe head is compatible with commercial Bruker spectrometers without their modification.
