Sažetak
The construction of the insulating column of the horizontally mounted Van de Graaff accelerator has been implemented using the new composite materials with the corresponding mechanical and electrical characteristics. Three supporting bolts fix the equipotential plates and the system exhibits vanishing vibrations and a negligible decline. The low frequency stabilization of high direct voltage has been implemented controlling the spray voltage by the thyristor transducer. The signal proportional to high voltage fluctuations changes the thyristor triggering delay angle in the primary circuit of the spray generator. The mathematical model predictions of the high voltage stability are confirmed by the corresponding measurements. The achieved stability permits the proton implantation experiments and it is a reliable basis for designing high frequency stabilization even at very low energies.
