Abstract
Recent results of C-14 analyses at the ANTARES AMS Centre are presente d. Test measurements of C-14 blanks demonstrate an ultimate sensitivit y of the order of 10(-15) (C-14/C-12 ratio). Measurements of unknowns have been made with a precision in the range 1-1.5% using a ''slow cyc ling'' mode of operation where the injection magnet field is changed t o inject C-14 and C-13 alternately. Results are presented for a series of log coffins from cave burials in NW Thailand.
