摘要:

We describe a dc volume H−source, employing multicusp plasma confinement, which has been constructed for use with the TRIUMF cyclotron. An extracted H−current density of 12 mA/cm2has been obtained. Beam emittance and brightness have been measured as a function of current density and beam fraction. Beam brightness values for normalized beam emittances of the order of 0.2 &pgr;mm mrad at 81% beam fraction are typically 10 mA/(mm mrad)2[equivalent rmsB=223 mA/(mm mrad)2].
