Abstract

A new high-mass, high intensity injector for the SuperHILAC has been approved and is under construction at LBL. A high power intermediate charge state ion source and accompanying low-velocity linac will provide beams for subsequent acceleration by the SuperHILAC. Both axially and radially extracted ion sources will be accommodated and charge state analyzed in the 750 kV, 100 kHz Cockcroft-Walton terminal. The LEBT will provide isotopic analysis to 1 part in 300. A 5m long, 23.4 MHz Wideröe linac, operating in the π -3 π mode based on the GSI design accelerates typically a U⁺⁵ ion to 113 keV/a where it is stripped to U⁺¹¹ by a perfluoropolyether vapor stripper and further accelerated by the SuperHILAC. The space charge limit of the system is several electrical mA which will be approached in the intermediate mass range.
