Abstract

843,648. Ion sources. UNITED STATES ATOMIC ENERGY COMMISSION. Aug. 2, 1957 [Sept. 19, 1956], No. 24525/57. Class 39(1). In a plasma ion source comprising an electron emitting filament 21, an annular anode 13, an ion extracting and electron reflecting electrode 31, a coil 44 for producing an axial magnetic field and a gas inlet 41, only a relatively small surface area of the electrode 31 is exposed to the interior of the ionization chamber 12. An insulating re-entrant portion 33 of the envelope covers the electrode 31 except for the end of the central boss 32. An insulator 39 surrounds the boss 32. The gas inlet 41 is a passage communicating with the annular space between the re-entrant envelope portion 33 and the electrode 31. Envelope portion 33 is sealed to electrode 31 by an annular member 34 which is secured over a resilient seal 35. The member 34 has a projection which is sealed to the envelope portion 33 by a gasket 36. The anode 13 is provided with cooling fins 16 and the filament rods 22 are surrounded by a heat shield 29.
