Optimisation of cold cathode ion source model

G.E.Bugrov,S.K.Kondranin,E.A.Kralkina,V.B.Pavlov,D.V.Savinov,K.V.Vavilin,Heon-JuLee 한국물리학회 2003 Current Applied Physics Vol.3 No.6
This paper represents the results of the optimisation of cold cathode ion source model with 5 cm extraction aperture diameter. Inthis model, the glow discharge is utilised for generation of electrons in the cathode of the ion source. The various models withdierent lengths of cathode and anode are tested. The shortest model with 4.5 cm in length of cathode and anode each showssatisfactory operation and can be used in cases when the high values of extracted ion current are not required. The best model fromthe point of view of ion beam current value and eciency of the discharge is the model with cathode length of 7 cm and anode lengthof 7 cm. In this case, the obtained maximum ion beam current is 110 mA when the discharge current is 1000 mA. In case whenmoderate values of extracted ion beam current are necessary, it is possible to operate the ion source even without the anode magneticsystem.. 2003 Elsevier B.V. All rights reserved.
