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