ABSTRACT:
A sample holder for use in an EPR spectrometer is extruded using a material having a low dielectric constant. The extruded sample holder has a plurality of channels formed in it for holding sample material for testing. The shape and orientation of these channels are such that losses due to the high dielectric constant of the sample are minimized. Sample holders for cylindrical and rectangular cavity resonators and uniform field cavity resonators are disclosed, as well as for two-gap and four-gap loop-gap resonators.
