Bimodal Q-band Probe Head with Improved Signal-to-Noise Ratio in Pulse Electron Paramagnetic Resonance V. Denysenkov https://doi.org/10.25716/gude.14gh-qa3n

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.
