    Radiotherapy is unique as a medical specialty in that it depends upon physical sources of energy deposition within tissues to bring about profound and complex biological changes for the purpose of eradicating cancerous growths. Thus, it has the broadest interface with both physical and biological sciences of any clinical discipline. It is for this reason that progress in radiotherapy is continuall... View full abstract»

    The stored energy in dc accelerators capable of reaching terminal potentials of 30 or 40 MV is more than an order of magnitude greater than in existing machines. To analyze the concentration of electrical fields under surge conditions the accelerator has been modeled by lumped constant networks. The analysis shows that in structures similar to the present ones the voltage distribution during a sur... View full abstract»

    A review is given of early development work at the University of Wisconsin on electrostatic accelerators insulated by high pressure gas. This work started in 1933 and led in 1940 to a 4.5MeV accelerator. Starting in 1946 development work was initiated along three lines: 1) Bakeable high strength metal to ceramic bonding, 2) Organic-free pumping, 3) Metal charge carrying devices. In 1951 constructi...

    Charge-state fractions have been determined for iodine, selenium and bromine ions traversing oxygen, argon, krypton, xenon, carbon-foil and gold-foil targets. Particular attention has been paid to high charge states, some containing as little as 10-6% of the primary beam intensity. The measurements indicate that a TU tandem accelerator is capable of delivering useful beams of heavy elements up to ... View full abstract»

  • Heavy Ion Source with Pulsed Magnetic Field

    Publication Year: 1971, Page(s):85 - 86
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (318 KB)

    A compact P.I.G. ion source with pulsed field and end extraction is described. The source produces multiply ionized N, C, Ne, A, Kr and Xe. Pulsed currents of C3+, N3+, Ne3+, A3+, Kr3+ , Xe6+ between a few tens of ¿A and a few hundreds of ¿A have been obtained. Small size and power consumption make it compatible with a Van de Graaff terminal where space and power are at a premium. View full abstract»

    A compact pulsed-bean ion source injector was developed and installed on The University of Texas Tandem Accelerator. The injector consists of a direct extraction negative ion source coupled to a 100 keV Coskroft-Walton accelerator. Improvements in the arrangement and fabrication of the high voltage components of the injector are discussed. R. F. pulsing and klystron bunching of the ion beam is don... View full abstract»

    To utilize the full current capability of the regular or symmetrical cascade generator, the conventional selenium rectifiers have to be replaced by a series-connection of silicon diodes which are rather sensitive to overvoltages and overcurrents. The problem of the application and protection of silicon diodes in high voltage generators had to be overcome in connection with the design of an air-ins... View full abstract»

    An expression for the maximum H- current obtainable from an H+ beam by charge exchange in hydrogen has served as a guide in the design and development of a source of H- ions for booster injection into the ZGS. Here it is used as a criterion in the evaluation of testbench results obtained with the present test source. Space and power limitations in the 750-keV terminal of the preinjector have led t...
