Abstract
853,916. Nuclear fusion reactors ; discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. Dec. 8, 1958 [April 15, 1958], No. 39443/58. Classes 39(1) and 39(4). A device for establishing a body of trapped atomic ions in a predetermined zone in an evacuated chamber permeated by a containing magnetic field comprises means for generating and injecting a plurality of molecular ions in the form of a beam into the magnetic field in a direction normal to the field so that the molecular ions follow a curved path towards a high intensity arc discharge which generates atomic ions from the molecular ions, the atomic ions being trapped by the magnetic field in a circular trajectory smaller than the trajectory of the molecular ions. The principle of the invention is illustrated in Fig. 2. Molecular ions from a source 8 follow a curved path due to a magnetic field normal to the figure and pass through a high intensity arc 12, normal to the figure, where some of the molecular ions are converted to atomic ions which pursue the path 10. Unconverted molecular ions are collected at 15, and neutral particles produced in the arc escape along path 11 and may be utilized in particle accelerator or like apparatus. Fig. 4 shows a practical embodiment comprising an outer shell 36 and an inner shell 33 which can be evacuated through ports 37, 38 and 41, 42, the pressure preferably being reduced to 10<SP>-7</SP> mm. in the inner shell and 10<SP>-6</SP> mm. in the outer shell. Arc electrodes 27, 28 project trhough the walls of the outer shell into baffles 29, 30 provided on the inner shell. An axial magnetic field is provided by pole-pieces (not shown) and a mirror field is provided by coils 31, 32 to prevent atomic ions migrating in an axial direction. An ion source 491 may be of the mass spectrometer type and may inject deuterium ions with an energy of 300 Kev. through the outer shell and through an opening (not shown) in the inner shell into the path of the arc.
