   Abstract:
   In order to eliminate the problem of calibration in beam spot size measurements, a wide slit scanning technique has been developed. As the beam scans across the edge of a slit, the ions or electrons are collected, and the resulting signal is displayed on an oscilloscope. This trace is a two-dimensional picture of the convolution of the beam with the slit edge. A mathematical analysis of the signal allows the intensity distribution of the beam to be obtained. Experimental verification of the technique is described
