Technique of production of argon-37 at proton cyclotron and detector for measurements

The technology of production of the isotope Ar-37 at proton cyclotron is developed. It is based on irradiation of the Cl-37 target with the protons of energy of a few a MeV. The example of production of tiny amount of Ar-37 is described and discussed. The detectors to measure the intensity of the sample is discussed.
