Description

A surface-ionization ion source for the use of a thick target has been studied by an isotope separator on-line at INS using the 40Ca(p,2pn)38K reaction. The ionization efficiency and release time were measured for CaC2, CaO and CaF2 targets. The measured efficiency turned out to be about 20% both for tantalum and platinum surface ionizers. The release time was also deduced for each target at various values of temperature by measuring time distribution of the extracted radioactivity after bombarding the target for a short time. (orig.)
