Abstract
The AMS facility based on a 14UD Pelletron tandem accelerator has been upgraded in recent years to support an active and diversified research program. A new dedicated AMS ion source beam line merging at 45° with the existing injection line through a 45° electrostatic deflector is in operation. The multi-sample high-intensity Cs sputter ion source stands on a separate 120 kV platform and is remote-controlled through a hybrid infrared-fiber-optics link operated either manually or by the accelerator-control computer, ensuring safe and reliable operation. Independent current preamplifiers are used in Faraday cup current readings down to the pA range. The accelerator computer-control system was upgraded to LabView 6.1, allowing a PC server to control and read out all hardware components while one or more remote PC clients run the AMS software. Ad hoc sequences of commands, written in a script macro language, are run from a client computer to perform an automated AMS measurement. The present capabilities of the facility in terms of detected radionuclides and their sensitivities are listed.
