摘要： A high current (0.2 to at least 2 milliamperes), low-energy (2.2 to 4 MV) ion beam is generated and is utilized to produce clinically significant quantities of medical isotopes useful in applications such as positron emission tomography. For a preferred embodiment, a tandem accelerator is utilized. Negative ions generated by a high current negative-ion source are accelerated by an electrostatic accelerator in which the necessary high voltage is produced by a solid state power supply. The accelerated ions then enter a stripping cell which removes electrons from the ions, converting them into positive ions. The positive ions are then accelerated to a target which is preferably at ground potential. For a preferred embodiment, the solid state power supply utilized to develop the required voltages is a cascade rectifier power supply which is coaxial with the accelerator between the ion source and the stripper, and is designed to have a voltage gradient which substantially matches the maximum voltage gradient of the accelerator.

摘要： The voltage at the high voltage terminal of a first particle accelerator is stabilized particularly during pulsed operation by producing a compensating current at its accelerator terminal such as to maintain the voltage of the terminal constant. The compensating current is produced by a second particle accelerator coupled between the accelerator terminal and a high voltage terminal connected with a high voltage DC power supply. The charged particle flow through the second particle accelerator is such that the charge on the accelerator terminal of the first accelerator remains substantially constant even though the voltage at the high voltage terminal drops during simultaneous pulsed operation of both particle accelerators.
摘要翻译：第一粒子加速器的高电压端子处的电压特别是在脉冲操作期间通过在其加速器端产生补偿电流来保持端子的电压恒定。补偿电流由耦合在加速器端子和与高压DC电源连接的高电压端子之间的第二粒子加速器产生。通过第二粒子加速器的带电粒子流动使得即使在两个粒子加速器的同时脉冲操作期间高压端子处的电压下降，第一加速器的加速器端子上的电荷保持基本恒定。

摘要： A tandem ion accelerator is disclosed having a charge reversing device for recharging negative ions into positive ions. The recharging is carried out in a matter-free zone and a light source is provided having a high luminous density for recharging the negative ions into positive ions. Preferably a deflecting device is provided for displacing an ion path and the light source is arranged such that a path of the light emitted from the light source coincides at least with a portion of the ion path.
