    The advent of the isochronous cyclotron, capable of accelerating a wide selection of particles with energies variable up to limits previously inaccessible, has spurred the development of techniques leading to increased knowledge of orbit behavior and hence to external beams of greatly bettered quality. Among these activities are improved methods of magnet design, of field control and of beam diagn... View full abstract»

    The characteristics of a 10 cm P.I.G. (Penning ionization gauge) discharge and its application as an ion source at a low pressure are given. Using a hot cathode two regions of operation are found, one above and the other below 1 micron. Pulsed ion current reaching 1 Ampere could be extracted from this source through a 10 cm diameter gridded cathode at a discharge current of about 20 Amperesand a g... View full abstract»

    A description is given of a duoplasmatron type ion source which features a novel, open cylindrical extractor electrode, a visible arc chamber and a short-path magnetic circuit. The glass spacer in the arc chamber permits observation of the plasma and filaments. The short magnetic circuit gives high plasma density at low magnet and arc currents. The open extraction geometry provides high pumping sp... View full abstract»

    The development, characteristics and emittance of the Penning discharge ion source used in the Cosmotron injector are described. The maximum value of brightness reported is 3 × 1012 mA cm-2 rad-2 at 78 mA total current, 23 keV beam energy. The results are superior to recent values for duoplasmatrons from various laboratories, except for total current. View full abstract»

  • A Small "Cold-Cathode" High-Intensity Cyclotron Ion Source

    Cited by:  Papers (2)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (268 KB)

    High beam currents have been achieved with a radial source which fits into the 2-inch gap of a 30-inch cyclotron. The geometry is that of a cold-cathode or P. I. G. source. However, the cathodes are heated to thermionic temperatures by ion bombardment rather than a conventional high-current heated filament. The source is now in use and produces intense beams of H+, D+, He3, and alpha particles. In... View full abstract»

    Recent achievements with iridium surface ionization ion sources are discussed. These sources can be used to produce ion beams of elements with ionization potentials from 5-1/2 to 6 V, e. g., the IILA metals (Al, Ga, In and Tl), the rare earths, the heavier alkaline earths, and Li, in addition to the usual heavier alkalis. Ion beams of Li, Al, Ga, and In have been produced here. Ionization efficien... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (927 KB)

    The design criteria for a source of 5-10μA of He- ions suitable for tandem accelerator application have been investigated. The process used is a nearly-resonant charge exchange between He+ ions, from a duoplasmatron, and potassium vapor. In the He+ energy range of 5-25 keV, the He-/He+ yield has been measured as a function of He+ energy. Yields of ~2%/ have been observed. A He- beam emitta... View full abstract»

    Earlier versions of the He- source suffered from cesium metal collecting on insulators and entering the r. f. source. A single acceleration gap is used to reduce the number of insulators requiring protection and additional shielding of the remaining insulators is provided. The new version also uses a gridded focusing element. Additional baffling and smaller entrance and exit apertures for the exch... View full abstract»

    Several modifications of the ion source of a model EN Tandem Van de Graaff Accelerator have increased the production of 4He- beams by a factor of 100 over that first obtained with the source (~10 nA). While using H2 gas for charge exchange, the replacement of the source drift tube by a screen and the installation of a system for precise adjustment of the button alignment with respect to the extrac...

    A triode electron gun is described which has been developed to meet the increasing interest in short pulse high current operation. The gun is of variable perveance capable of injecting at least 15 amps under short pulse conditions (1 nanosecond) and 1.5 amps under long pulse conditions (5 microseconds) with a beam diameter of 1 cm. Considerations of beam geometry have lead to the choice of a conve... View full abstract»

    In the design of high-perveance electron beam devices, it is necessary to evaluate the effects of the self-fields on the beam trajectories as well as the effects of any external electromagnetic fields that may be present. This paper describes a means whereby the self-consistent solution of Poisson's equation, the relativistic equations of electron motion, and the equation of charge continuity, all...
