Abstract:

A velocity distribution function for a molecular beam formed from an aerodynamically accelerated source is developed from the Maxwell-Boltzmann distribution function for an effusive source. The distribution function is presented in a form compatible with the time-of-flight measurement technique for the experimental determination of such distributions. The expressions for several parameters of general interest, such as static temperature, speed ratio, energy, and velocity, are also presented. A description of a computerized data reduction technique for time-of-flight measurements is given. In addition, the effect of shutter functions and time delays in the accurate measurement of velocity distributions are discussed.
