Abstract
THE cyclotron at present has a limited voltage amplification due, in part, to a space charge built up within the duants. The space charge density may be lowered by reducing the intensity of the ion beam alone, or by increasing the high-frequency alternating potential on the duants, thereby reducing the number of times the ion must circulate before attaining the desired velocity. These two methods of lowering the space charge are obviously undesirable. If the number of times the ions is accelerated in one revolution is increased there will be a resultant decrease in space charge density.
