CURRENT STATUS OF THE C-14 AMS PROGRAM AT THE UNIVERSITY-OF-WASHINGTON

Recent modifications of the C-14 AMS system at the University of Washi ngton Nuclear Physics Laboratory have significantly improved the perfo rmance of the system. Analysis of various data sets produced under our ongoing program to evaluate the precision and accuracy of the C-14 AM S measurements shows that less-than-or-equal-to 3 parts per thousand o f the scatter in the measurements cannot be accounted for by counting statistics uncertainties and indicates that inaccuracies in the measur ements introduced by systematic errors are less than 3 parts per thous and. Current scientific studies being undertaken with the University o f Washington C-14 AMS system are discussed briefly.
