Abstract

For first investigations of hot dense matter produced by intense heavy-ion beams we built an electrostatic quadrupole doublet that focused Ar+and Kr+ ions of 45 keV/amu after acceleration through the radio frequency quadrupole (RFQ) accelerator at the GSI onto a small spot of approximate area 1 mm2. This beam then deposited a specific beam power of about 1.5 GW/g to targets.
