Query: Beam Particle Identification and Tagging of Incompletely Stripped Heavy
  Beams with HEIST   A challenge preventing successful inverse kinematics measurements with heavy
nuclei that are not fully stripped is identifying and tagging the beam
particles. For this purpose, the HEavy ISotope Tagger (HEIST) has been
developed. HEIST utilizes two micro-channel plate timing detectors to measure
time of flight, a multi-sampling ion chamber to measure energy loss, and a high
purity Ge detector to identify isomer decays and calibrate the isotope
identification system. HEIST has successfully identified $^{198}$Pb and other
nearby nuclei at energies of about 75 MeV/A. In the experiment discussed, a
typical cut containing 89\% of all $^{198}$Pb$^{+80}$ in the beam had a purity
of 86\%. We examine the issues of charge state contamination. The observed
charge state populations of these ions are presented and are moderately well
described by the charge state model GLOBAL.
