Molecular Beam Methods of Evaluating High Energy Sources for Advanced Propulsion Methods

摘要

The report summarizes research on designing an apparatus to obtain high resolution of relative kinetic energy for collision experiments in the electron volt range. Because it is the center-of-mass system that is important in the interpretation of experiments, energy spreads in both the projectiles and the targets are considered. The target particles are in the form of a crossed beam. Basically, the scheme consists of observing only those reaction products that are formed in a short range of primary-beam flight times. Two research areas are summarized. One deals with the measurement of the electron affinity of NO2 and the other concerns the systematic error in beam-gas experiments.
