The Off-line Target/Ion Source Test Facility (TISTF) serves
as the initial theater for development of RIB ion sources, here candidate
target/ ion source designs are evaluated and developed using stable feed
species while having no impact on other HRIBF accelerator resources.
This facility consists of a high voltage platform, target/ion source mounting
apparatus, beam transport lenses, an emittance measurement device, a magnet
for mass selection, a charge exchange cell, a device for measuring charge
exchange efficiencies, and an electrostatic beam energy analyzer. The emittance
measuring apparatus is located before mass analysis while the charge exchange
cell and an apparatus for measuring the charge exchange efficiencies and
beam energy distributions are positioned after mass analysis. The facility
is equipped with a gas manifold for introducing noble gases into the source
through a standard leak calibrated against Xe for use in measuring the
ionization efficiency of RIB ion sources during operation. The facility
also includes various apparatus for the injection of well defined quantities
of chemically reactive species into RIB target/ ion sources (e.g. F, Cl,
As, etc.). The high voltage platform was designed and equipped with
all power supplies necessary for testing RIB ion sources. Power supplies
mounted on the high voltage platform are powered by a 15 kW motor generator
set specifically designed for testing the RIB sources.
