There is a present need to characterize trace elements in                       electronic materials at impurity levels of sub parts-per-billion.               This award is for the development of such an instrument for                     stable trace element analysis of electronic materials using                     Accelerator Mass Spectrometry (AMS). While AMS has been applied                 to radioisotope determinations with extremely high sensitivities,               existing AMS instruments are not designed for stable element                    analysis and can not adequately perform these measurements                      without extensive modifications. We propose an instrument with an               ultra-low sample-contamination UHV sputter ion source which                     injects mass-analyzed negative secondary ions from                              the sample into a 3 MV tandem accelerator. During tandem                        acceleration, electrons are stripped from the ions; for charge                  states greater than 2+, only atomic ions survive. Momentum/charge               and energy/charge discrimination, followed by velocity and total                energy detection, provide unambiguous elemental identification                  with a sensitivity of 1 part-per-trillion. The proposed                         instrument will provide a super-sensitive trace analysis                        technique which is applicable to a large variety of samples.
