Preparation, Characterization and Testing of Implanted 37-Ar-Layers.
37 Ar atoms were produced via the 37Cl (p,n) 37Ar reaction using the 30MeV proton beam of the Cyclone 30 cyclotron of the UCL and a NaCl target. After ionization, 37 Ar2+ ions were implanted at 20 keV into 20 mu m thick Al foils. The number of 37Ar atoms in the layers was determined by measurement of the 2.62 keV KX-rays (emitted during the EC-decay of 37Ar) with a gas-flow proportional counter. under vacuum and under intense thermal neutron irradiation, the implantation was found to be stable. Furthermore, the layers were found to be suited for (n,p) and (n, alpha) measurements.
