Technical Report ·
OSTI ID:4127243
Development of a 10-ma proton beam source is described. A study was made of the production of intense plasma, in particular, the discharge mechanism, characteristics of high-frequency discharges, determination of the impedance of an oscillating circuit loaded wiih a plasma, the high-frequency electric fteld created by the self-induction of an oscillating circuit, and the definite source. Beam extraction is next considered with particular reference to space-charge. An extraction apparatus and experiments with it are described. A threeelectrode apparatus for beam focusing is described. Performance data are given as curves of power consumed, gas consumption, and extraction yield as a function of target current. (T.R.H.)
