• Production of C- Directly from CO2 Using the ANIS Sputter Source

      Heinemeier, Jan; Andersen, Hans Henrik (American Journal of Science, 1983-01-01)
      Micro-ampere beams of C- have been produced with the Aarhus negative-ion source, operated on CO2 gas. The efficiency of the source and memory effects have been measured, using 13C-enriched CO2, in order to evaluate the applicability of the source to 14C dating by accelerator mass spectroscopy.
