Abstract
The disclosure relates to a particle accelerator which comprises two accelerating tubes as well as a charge-exchange channel, whereby the vacuum pump for evacuating from said charge-exchange channel gas particles injected therein is not connected to the high-voltage side but, via a vacuum tube, to the low-voltage side of the particle accelerator. This means a substantial simplification of the maintenance of the vacuum pump. In addition to that a motor and a generator are no longer required. By providing the vacuum pump with equipotential plates, which comprise pump holes arranged eccentrically round the center of the vacuum tube, the gas particles are in this configuration are accelerated while retaining the high breakdown strength.
Claims12
A particle accelerator comprising:
- at least two accelerating tubes, each having a high-voltage side and a low-voltage side;
- a charge-exchange channel having openings near said high-voltage sides of said at least two accelerator tubes;
- means for the injection of a gas into said channel between said high-voltage sides of said at least two accelerating tubes;
- at least one vacuum pump and open connection with said channel;
- and
- a vacuum tube in open connection with said channel, said vacuum tube being at least partially connected between said high-voltage side and said low-voltage side, and wherein said vacuum pump is connected to said vacuum tube at said low-voltage side.
