title = "A new high temperature isol ion source",
abstract = "A new high temperature ion source for on-line isotope separation applications has been developed. Off-line efficiencies of up to 13% for Xe have been measured. On-line efficiencies of 3% for Tl while operating in the plasma mode and about 30% for Fr while operating in the thermal-ionization mode have been obtained. The release of Tl from this source has been determined to occur with a half-life of about 0.6 s and Fr release was measured to be as short as 0.8 s.",

note = "Funding Information: The University Isotope Separator at Oak Ridge (UNISOR) \[1,2\] facility is an ISOL (isotope separator on-line) system at the Holifield Heavy-Ion Research Facility at Oak Ridge National Laboratory and has enjoyed considerable success in recent years in tile discovery and study of neutron-deficient nuclei far from the line of beta stability. Much of this work has been accomplished with an ion source of the Nielsen \[3,4\] oscillating-electron type modified for on-line use \[6\]. Due to an operating temperature of about 1000°C for this source, high efficiency on-line separation was accomplished only for elements with relatively high vapor pressures such as Hg, T1, Xe and I. In order to make new elements accessible and shorten hold-up times for the elements already possible, a new higher temperature ion source was needed. High efficiency, good mass resolution, long * Supported by the Laboratory Graduate Participation Program administered by the Oak Ridge Associated Uni-versities for the US Department of Energy. ** UNISOR is a consortium of University of Alabama in Birmingham, Emory University, Furman University, Georgia Institute of Technology, University of Kentucky, Louisiana State University, Oak Ridge Associated Uni-versities, Oak Ridge National Laboratory, University of South Carolina, University of Tennessee, Tennessee Technological University, Vanderbilt University, and Virginia Polytechnic Institute and State University.
