The report is the ninth in a series of summaries on the use and development of the NRL 5-MV Van de Graaff accelerator and associated instruments. In this reporting period 1 January to 31 December 1973, for the first time anywhere, a measurement to determine dose-rate effects in the simulation of neutron damage to reactor materials with 2.8-MeV nickel ions has been made. The nickel-ion flux was changed by a factor of 100, all other parameters being constant the relationship between specimen swelling and temperature was determined for two fluxes. New species of ion beams are now available from the 100-keV ion-implantation accelerator this apparatus has been used for many optical and electron device-related implantations. The very successful operation of the modified Hill-Nelson sputtering ion source in the Van de Graaff has opened the way to a wide variety of metallic ions with MeV energies. A new digital-optical telemetering system has added significantly to the efficiency of Van de Graaff operation. Modified author abstract
