Abstract
An ion accelerator is described that delivers magnetically separated ion currents of 0.1–20 μA at 5 eV–10 keV energy into targets of 5 mm2. An electrostatic decelerator in front of the target permits continuous lowering of the ion energy to ca. 5 eV. The accelerator has been used mainly for the production of 14C+ ion beams from 14CO2 for the study of the hot atom chemistry of carbon in solid benzene. The ion source is of all metal construction and is a straight capillary arc type. It delivers C+ currents of approximately 2 μA, obtained at 0.2–0.5% efficiency from the 14CO2 source gas.Keywords
