The day started with a tour of the John de Laeter Centre (Jd LC) facilities incorporating the Tescan integrated mineral analyser (TIMA; ), which was the key instrument of relevance to the workshop. Dr Mark Aylmore, recently appointed to take on the role of Applied Mineralogist in the Jd LC, chaired the workshop that included presentations from: • Dr Kamran Khajehpour (AXT), who gave an overview of automated mineralogy and supported by Esben Kjaer (Struers) who gave a brief overview on sample preparation techniques. The negative ions that enter the accelerator are attracted to the high-voltage terminal, which is what accellerates the CAMS LLNL employs a tandem Van de Graaff accelerator, in which a second acceleration of millions of volts is applied.In all tandem accelerators, atoms are stripped at the high-voltage terminal using either a thin Carbon foil or Argon gas.AMS is a highly sensitive method for isotopic analysis that has numerous key applications that are only growing with advances in technology.High costs and technical complexities that arise with the use of a particle accelerator are the only limits to the widespread use of AMS.As a special first edition feature, we have included an entire page that highlights the basic instrument capabilities of each facility.
Transmission through a foil changes with time due to radiation damage and foil thickening, thus gas strippers are used in all modern analyzers due to their increased transmission stability.An electrostatic accelerator works by accellerating particles though a magnetic field generated by high voltages using a mechanic transport system that continuously transports charges from ground to the insulated high-voltage terminal.All tandem accelerators with a maximum terminal voltage above 5 MV use such a mechanical system.AMS requires a particle accelerator, originally used in nuclear physics research, which limits its widespread use due to high costs and technical complexity.Fortunately, UC Davis researchers have access to the Lawrence Livermore National Laboratory Center for Accelerator Mass Spectrometry (CAMS LLNL), one of over 180 AMS research facilities in the world.
