Abstract

Extended work, involving background effects, to confirm the charge-inducedX-ray (CHIX) phenomenon is reported. PIXE studies in pure metal targets surroundedby a special type of glass insulating material (Macor) produced higher backgrounds,in general, compared to corresponding observations made in the absence ofthe insulator. Experiments were conducted using low-energy protons of 700keV and beam currents ranging between 1–10 nA. Signal-to-noise ratiosand detection limits are compared and discussed in the light of the unusualhigh X-ray yields produced by the CHIX phenomenon.
