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.
