Abstract

The first on-line tests of the ion sources to provide radioactive ion beams of ^69,70As and ^17,18F for the Holifield Radioactive Ion Beam Facility have been performed using the UNISOR facility at HRIBF. For ⁷⁰As the measured efficiency is 0.8 ± 0.3% with a hold-up time of 3.6 ± 0.3 h as measured with ⁷²As at a target temperature of 1270°C. For ¹⁷F the efficiency for Al¹⁷F is 0.0024 ± 0.0008% with a hold-up time of 16.4 ± 0.8 m as measured with Al¹⁸F at a target temperature of 1470°C.
