The present paper discusses an experiment, using a Middleton sputter ion source, where a sensitive search was made for 14N- ions in the presence of an intense carbon beam. It was found that negative nitrogen ions, capable of withstanding acceleration

Mass spectrometric methods have long been suggested as ways of measuring (14)C/(12)C ratios for carbon dating. One problem has been to distinguish between (14)N and (14)C. With negative ions and a tandem electrostatic accelerator, the (14)N backgroun

It is our belief that major advances in the generator voltages used in D. C. accelerator technology will only be achieved after the generators are designed for both D. C. operation and for the transient conditions that are present during discharge. T
