SIRIUS – A new 6 MV accelerator system for IBA and AMS at ANSTO

Geant4 X-ray fluorescence with updated libraries

“…PIXE spectra were experimentally measured at the ANSTO heavy ion microprobe beamline [27] using 2 and 3 MeV proton and 10 MeV He 2+ ion beams with beam currents varying between 0.5 and 2.5 nA. For X-ray detection, a 100 mm 2 high purity Ge detector with a solid angle of 90 msr was used.…”

“…Finally, the G4-ANSTO and G4-default (see Table 1) were compared to experimental measurements performed at ANSTO using the 6 MV SIRIUS Tandem Accelerator [27]. The experimental spectra were normalised to the highest line of the G4-ANSTO X-ray emissions.…”
