Abstract: An electron spin resonance spectrometer which is dedicated to a specific narrow range of tasks is reduced in size such that, as contrasted with the usual laboratory ESR spectrometers, it is easily and readily portable and can be carried to various locations to conduct tests. It uses a much smaller magnet structure than usual, a self contained single board computer, and a microwave source which is adjustable by the computer. The microwave source operates in the 2 GHz range and is connected through a circulator with a matching circuit which inductively couples the microwave signal to a sample chamber/resonator positioned in the magnetic field of the magnet structure. An oscillator provides a audio frequency signal which is combined with a slow ramp signal from the computer to modulate the output of the magnet structure.
