FREQUENCY SWEEP ESR SPECTROMETER FOR DOSIMETRY AND DATING

Measuring the radiation damage in a substance by ESR is now common and much progress has been made in ESR methods. Standard ESR generally requires setting up the large scale electromagnet, having a regulated power supply and an observation area in the laboratory. At present conducting experiments outside a laboratory is impossible. Dosimetry and dating require that samples be brought back to the laboratory for study. We have built an experimental, small-sized ESR apparatus, which can be transformed into a battery-powered portable version.
