1283415 lon beam tubes NATIONAL ELECTROSTATICS CORP 3 Sept 1969 43545/69 Heading HID A high voltage accelerator comprises an accelerating tube 14 connected between a high voltage-electrode 18 and a grounded electrode 28 and an intermediate electrode '74 between electrodes 18 and 28 'has a vacuum pump 72 mounted therein and.connected to the interior-of the tube 14, and wherein .the .pump 72 is powered by a rotary generator 102 connected via insulating shaft 106 to a motor 104. The accelerating 'tube-may be subdivided into a number of insulating sections '56 separated by -conductive -aper. tured isolating diaphragms 58, as disclosed "Specification 1,283,414. The pumps 72, e;g. of the getter-ion -orbitron type, are 'preferably connected one to each section 56 with common shafts 106, adjacent an 'insulator 36, axially aligned between the pumps and motor 104 for connecting the separate rotary generators 102. To enable the shafts to withstand the voltage between adjacent intermediate electrodes 74, which may exceed 1,000,080 volts, the shafts (Comprise insulating cylinders 108 with metal discs 110 therebetween which ,correspond with the metal discs 40 between the -insulating sections ,38 of .the insulator 36. Each corona "discharge electrode 112 mounted on a disc 40 with a point 114 directed towards .an adjacent -disc 40 has an additional point 116 directed towards a respective disc 110 on the shaft 106 to .equalize the -potential .drop .along the shaft 106 and insulator 36. Other devices requiring electrical power and connected to the interior of the accelerating tube, the ion source for example, may also be powered by a rotary generator connected via shaft 1()6 to motor 104.
