High energy molecular beam source in the range of 1 to 5 eV is one of the most important tools to explore gas-surface interaction involving chemical reaction. Although the seeded beam and the arc-heated beam have been employed for such purpose, they have the drawback of the low beam intensity and the generation of undesirable excited species. It is known that the shock heated molecular beam is capable of overcoming these problems. However, the quite low repetition rate less than 1Hz has made practical application difficult in molecular beam scattering experiment so far. In this study, we examine the capability of the small shock tube as a molecular beam source using a current-loop valve and modify it to improve the performance.
