Abstract

We describe a submicrosecond resonator and receiver system for use in pulsed magnetic resonance at 220 MHz. This new resonator and receiver system design enables a reduction of the dead time, and in principle its complete elimination. We show experimentally that the resonator and receiver system permits the detection of free induction decay signals 300 ns from the end of the transmitting pulse, even with large (55-ml) saline samples. This apparatus was specifically developed for in vivo Fourier transform electron paramagnetic resonance detection of free radicals; however, it can also be used in pulsed nuclear magnetic resonance imaging of solids with applications in materials research and the polymer industry.
