STIM data is often collected concurrently with PIXE data. In such instances STIM provides specimen thicknesses to normalize PIXE data for teh calculation of quantitative elemental concentrations. It is thus possible to observe fine features in thin samples and STIM can provide a rapid, histological assessment of a specimen. STIM image of a portion of an insect wing. The image size is 2 x 1.5 mm.
Darker regions represent greater specimen thickness.
The mass of the imaged portion of the wing was determined to be 640 ng. A.J. Antolak, G. Bench, A.E. Pontau, D.H. Morse, D.W. Heikkinen and D.L. Weirup, Nucl. G.S. Bench, A. Saint, G.J.F. Legge, M. Cholewa, Nucl.
