Abstract:

In this paper we represent our original developments of a compact electron spin resonance (ESR) instrument, which is featured with high performance, low cost, reliability and simplicity, open architecture, small size, and a wide range of functional modules and units. Various constructions of the ESR spectrometer microwave units were analyzed. An optimal two-cavity construction for autodyne type ESR spectrometers were finally developed and investigated experimentally. The ESR instrumentation presented also involved compact magnet systems based on electromagnets and permanent magnets with high uniformity of magnetic field. The specifications of the compact ESR instrument developed, as well as a list of applications, are presented. Some special applications of compact ESR spectrometers are discussed.

Key words: electron spin resonance(ESR), homodyne and autodyne ESR spectrometers, magnet systems, ESR applications
