Uniform Field Re-Entrant Cavity for Improved Pulse EPR
A recent publication in Applied Magnetic Resonance describes a new uniform field (UF) resonator that has been optimized for pulse experiments. The UF geometry is described as a re-entrant cylindrical TE01U cavity at Q-band (34 GHz). The re-entrant geometry is calculated to have the same electron paramagnetic resonance (EPR) signal intensity as a traditional TE011 cavity, a 60% increase in average resonator efficiency Λave over the sample, and has a B1 profile that is 79.8% uniform over the entire sample volume (98% uniform over the region-of-interest).
