Abstract
An EPR resonator for a cylindrical TE01n microwave mode, where n=1, 2, 3, or 4, has: a cylindrical body () which has an RF absorption of less than 5% at RFs below 1 kHz, a first plunger () delimiting the resonating volume within the body in an axial direction at a first end and a second plunger () delimiting the resonating volume within the body at a second end, the second plunger having an opening () for inserting an EPR sample. The first and second plunger each has a spiral winding of an electrically conductive filament wherein neither the ends nor neighboring turns of the spiral windings have electrically conductive connections prone to forming electrically closed loops. Using spiral winding plungers for cylindrical TE01n microwave modes provides equivalent functionality compared to conventional plungers, but without creating Eddy currents at frequencies lower than the frequency of the TE01n microwave mode.
