Abstract

A special collector is being developed to determine the two-dimensional mass distribution of ions from a low energy ion beam and of the particles backscattered from a target by using an arrangement of an array of quartz crystal microbalances.The distribution of the scattered particles during the bombardment of a collector surface with gold ions will be of special interest for the experimental determination of the atomic mass of gold in the unit kilogram, where decelerated gold ions are to be accumulated in a collector to a weighable mass. The current state of the research work is presented.
