Abstract : Two types of vacuum vibrator sources have been developed. Conventional magnetic types operated at several hundred cps and stepped horn resonator systems operated at frequencies of 15 to 60 Kcps. Both types performed satisfactorily under test. A study of characteristics of the sources was carried out. A comparison between the properties of the vacuum vibrator and the conventional radio-frequency spark showed that almost all of the advantages were in favor of the vacuum vibrator. These included higher and more stable ion currents, lower energy spread, smaller sample consumption, easier to operate and less equipment required. The main disadvantage is that the multiply charged ions are more abundant. This, of course, is sometimes an asset. Techniques were developed for the ionization of nonconductors with the vacuum vibrator source. (Author)
