The Argonne Tandem Linear Accelerator System (ATLAS) has been operating on a 24 hour, seven days a week schedule since the beginning of Fiscal Year 1994. Twenty-six different ion species ran during this period in 71 separate experiments. During the p

The production of high charge‐state ions in an electron cyclotron resonance ion source has been studied as a function of time using a pulsed Nd:YAG laser to ablate heavy metal (bismuth) ions into the plasma. The time required to produce a charge st

A direct ion plasma sputtering effect has been observed in an electron cyclotron resonance ion source and developed into a reliable and simple method for producing ion beams from some solid materials. We describe the ion sputtering technique used wit

The first AMS measurements of 39Ar and 81Kr have been performed by combining positive-ion production in an ECR ion source with acceleration to 6 MeV/A in the ATLAS linear accelerator and detection in a gas-filled spectrograph. Sensitivities of 39Ar/A

The recently completed positive-ion injector for the heavy-ion accelerator ATLAS is a replacement for the tandem injector of the present tandem-linac system. Unlike the tandem, the new injector provides ions from the full range of the periodic table.
