Study of inhomogeneities in sources prepared for alpha-particle spectrometry using scanning probe microscopy.
For high-resolution alpha-particle spectrometry, sources of high quality must be prepared by methods giving the thinnest and most homogeneous deposit possible on a suitable support. Surface characteristics of several types of alpha-particle sources were studied using a scanning probe microscope. Major inhomogeneities were observed, which means that the materials and techniques used for thc preparation of sources must be improved.
