Abstract
The aim of the present work was development of a highly efficient surface ionisation ion source for alkaline-earth elements. An ionisation efficiency of strontium up to 60% with a sample of 10{sup 17} atoms ({approx_equal} 10 mg) and separation time about two hours was reached by means of electron bombardment. The main purpose of this ion source is detection of 10{sup 7} atoms of {sup 90}Sr (7mBg) in the presence of a surplus of up to 10{sup 17} stable strontium atoms. The ion source is used in combination with the fast running atom beam recharge system at the RISIKO facility (Mainz, DE). (author). 5 refs.; 6 figs.; 2 tabs.
