An apparatus has been built which is capable of generating uniform charged particles of hydrogen isotopes. Two unrelated physical processes are used to produce charged jets of controlled size and current. The jets later break up into uniform sized charged droplets. In both processes, charging of the liquid is accomplished by placing a sharp electrode inside the liquid and by raising it to a high potential. The first process is to electrostatistically spray the charged liquid to form a fine jet of controlled size and current, whereas the second process is Rayleigh's method of uniform droplet production. This method consists of breaking up a smooth jet of predetermined size into uniform drops using an externally excited acoustic wave. Uniform charged particles with charges up to one-third of the Rayleigh limit were generated through the first process, while in the second process the maximum charge was approximately one-quarter of the Rayleigh limit. A wide range of sizes can be produced using either process.
