The electrostatic and electromagnetic straight-line accelerators originated by Robert Van de Graaff for nuclear science have, for very heavy ions, moved toward the GeV level through advances in high voltage technology applied to the multi-stage (tandem) acceleration of multistripped ions. An account is given of the discreet steps in this exponential progress which depends basically on the maximum...
It can be claimed that gases at elevated pressure are the logical and, perhaps, inevitable, replacement for atmospheric air as the primary insulating medium for transmission of high-voltage power. Such compressed gas-insulated lines would reduce or eliminate most of the problems of open overhead lines, i. e., the inadequate insulating strength of air at 1 atm, corrosive contamination of insulators,...
The increasing use of gaseous dielectrics at elevated pressures is one of the significant trends in high-voltage engineering today. Such compressed gases can be superior to solid and liquid dielectrics and to high vacuum insulation, particularly for long gaps and high voltages.
