In this paper a new type of high-oensity caesium plasma ion source is descrioed, which is capable of producing Cs-beam currents of up to 300 d. The ion emihing surface 'n the caes:Lm plasma conforms automar:cally to the accelerator geometry IO give perveance match, provided that the ion density is c0rrect.y adjusted with respect to the require0 beam energy. Ready operation of tne source at different energies with constant perveance is facilitated :n tn's way. Consequently, me beam oivergence is practica1.y indepenoent of the beam energy. The plasma density is ma'ntained at the req-ired level by controlling tne temperature of the source chamber walls on which atonic caesium is aeposited. The ion soJrce ana the beam transport line have been deve oped at Culnam and del'ver a lowdivergence 1.5 pA Cs oeam at the gun output, with an energy of JP to 25 keV. The apparatus now Serves as the injection Dart of the heavv ion beam del ection analvser of the ISTTOK tonamak in Lkbon. '
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
