Diseño y mediciones con una fuente de iones del tipo de arco colimado en campo magnético I

Abstract

An experimental ion source the hot-cathode are discharge type has been constructed. The are is colliraated in a magnetic field and the extraction of the ion beam is axial. Detailed measurements of the characteristics of this ion source have been efectuated. The maximun total ion curren obtained is 40 mA. There is evidence of secondary electrons whose falsificating effeets on the measured current had to be eliminated- Calorimetrical measurements of the target current are in agreement with the electrical ones. A convenient means of regulation or modulation of the beam current of the source is described.
