Brief History of Tandem Electrostatic Accelerators and Future Trends

Greg Norton, National Electrostatics Corp.
Building 6008, Conference Room

In 1936, the first modern column structure for the electrostatic accelerator was designed and built at the University of Wisconsin coming less than 1 1/2 years from the first experiment with a pressurized Van de Graaff built by the same group. Although the fundamentals of this tandem like design have not changed, refinements to the column structure detail, changes in basic acceleration tube design and charging system have allowed the electrostatic accelerator to evolve to meet the demands for ion beam energy, quantity and quality. Up until the late 1970's, electrostatic accelerators were being built larger to accommodate increasing demands for higher beam energy. Today, the ion beam energy spread, brightness, and higher beam currents are driving the market for new facilities. This talk will discuss the trends and requirements for the new applications for electrostatic accelerators.

Refreshments will be served at 2:40 p.m.
