Abstract:
A resonated coil driver designed for rapid scan electron paramagnetic resonance (EPR) is described. Rapid scan EPR requires larger magnetic field coils and a more powerful magnetic field modulation than those designed for conventional continuous wave EPR. There are two advantages of a resonated coil driver: i) by resonating the scan coils the reactive components are removed, which allows the coils to be driven with much lower voltages, and ii) by resonating the coils a near‐perfect sinusoidal scan is ensured. Performance of the coil driver is improved when Litz wire coils are used. With coil diameters between 3 and 3.5 inches, sweeps can be generated with widths up to about 80 G peak‐to‐peak and frequencies up to about 150 kHz, which permits sweep rates of more than 8 MG/s. The magnetic field is uniform over the sample length of a Bruker dielectric resonator. Enough detail has been presented for other laboratories toimplement this design to perform rapid scan EPR. © 2012 Wiley Periodicals, Inc.
