An on--demand beam pulsing system is useful for the PIXE analysis of delicate objectS. IXX (or PIXE--induced XRF) is more suitable than PIXE in terms of damage to the sample. Some new PIXE and IXX applications of archaeological paper--like samples in recent years are given.展开更多

First, it can be used to avoid or significantly reduce background and spectral interferences from major elements in the sample by proper selecting the primary target. Second, target damage is greatly reduced, so that it is more suitable for the analysis of heatsensitive and delicate specimens. A new IXX system with a very tight geometry is described. Some of its performances and preliminary applications are presented.展开更多
