Development of the Chalk River program for 36Cl

Abstract The AMS program at the Chalk River TASCC (Tandem Accelerator Superconducting Cyclotron) facility is directed toward 36 Cl measurements in hydrological and other samples. The automatic data acquisition/accelerator control system has been commissioned and progress is reported on particle identification with a Bragg-type detector and 36 S background control with a gas-filled beamline magnet. Evidence for large Cl memory effects in a Hiconex 860 sputter source is also presented.
