Preparation, characterization and testing of implanted (37) Ar layers
(37) Argon atoms were produced via the (37) chlorine (p, n) (37) argon reaction using the 30 MeV proton beam of the Cyclone 30 cyclotron of the UCL and a sodium chloride target. After ionization, (37) argon (2+) ions were implanted at 20 keV into 20 µm thick aluminium foils. The number of (37) argon atoms in the layers was determined by measurement of the 2.62 keV KX-rays (emitted during the electron cyclotron (EC)-decay of (37) argon 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.
