Abstract

With the recent addition of a high-energy analysis beam line, the capability to measure 129I has been developed at the NSF-Arizona AMS Laboratory. Preliminary measurements have been made using the +4 and +5 charge states at 2.1 MV with a gas stripper. The current system employs a 90° injection magnet (r=0.36 m) following the ion source. Analysis components following the accelerator include an electrostatic quadrupole doublet lens, a 15° electrostatic deflector (r=1.25 m), a 90° analysis magnet (r=1.27 m) and a 77° spherical electrostatic analyzer (r=2.0 m). Detection of 129I is accomplished with a silicon surface barrier detector. Operation of this system with various iodine samples will be discussed.
