Component selection for a compact micro-XRF spectrometer.

Kurzbeschreibung (Abstract)
The performances of a number of commercially available components which together can be employed to assemble a compact micro-XRF spectrometer were compared. The purpose of such a spectrometer is to permit local, non-destructive analysis of various materials; its compact nature will allow it to be used on-site, i.e. at the location where the investigated objects/materials are present rather than in a laboratory. The performances of two polycapillary lenses (of different manufacture) and one monocapillary tube were compared in combination with a mini-focus x-ray tube with Mo anode. The use of an Si-drift chamber and an Si PIN-diode detector was investigated and the achievable minimum detection limits for trace elements in glass and silver matrices were determined. Finally, the effect of using mini-focus tubes (with 250 µm focus) as opposed to the use of a more conventional x-ray source (1 mm focus) on the obtained beam size was investigated.
