Abstract
As a part of Australian Federal Government funding in 2009 to establish a centre for
accelerator science a new 6 MV state of the art accelerator – SIRIUS – was purchased. The
system is now commissioned and comprises ion sources and beam lines to cater for a wide
variety of both IBA and AMS applications. The ion source used for AMS (MC-SNICS) is
the latest incarnation followed by 45 degree spherical ESA(R=0.3 m) and double focusing
injection magnet (R=1 m, ME=20) prior the accelerator. At the terminal we have a choice
of 2 stripper gasses and/or stripper foils. The high-energy spectrometer for AMS consists
of a 1.27 m radius analyzing magnet with ME=176, 45 degree ESA (R=3.81m), followed
by a switching magnet and 3 beam lines: one with a standard multianode ionization
chamber; one with an absorber cell in front of the detector; whereas the third beam line
has a time-of- ight detector. Details of the instrument design and performance data for
10Be, 26Al and 36Cl will be presented. © The Authors
