A scheme is presented for increasing the beam output from a synchrocyclotron by placing a smail dee system, covering the orbits of ions with energies of up to about 5 Mev, opposite the live dee at the center of the machine. A high-voltage radiofrequency signal is fed to the small additional dee which is in antiphase to that on the main dee. This system is derived from the main oscillator system after amplification in a separate power amplifier. The auxiliary amplifier is pulsed on at a time slightly before the main dee commences to capture ions from the ion source, and is switched off when the captured ions have gained on the average a few Mev. Results are reported from preliminary tests made with the Harwell 110-in. synchrocyclotron, using an 11-in. nadius dee with a total operating time of approximately 50 mu sec in each main modulating cycle.
