    Abstract. Molecular beam source using a small shock tube has the potential to frequently generate high energy molecular beam in a range of 1 -5 eV without any undesirable impurities. We measured shock Mach numbers in 2 and 4-mmdiameter straight tubes to know about the propagation of shock wave in a very small shock tube. In addition, we measured shock Mach numbers in convergent shock tubes of which diameters linearly decrease from 4 mm to 2 mm, which demonstrated the possibility of a convergent shock tube to generate higher energy molecular beam than straight one
