    Abstract
  • A PVF2 (polyvinylidene fluorid) gauge, which is suitable for the measurements of the response of the curved surfaces in small space on high velocity gas fluid is described in this paper. A sensitive trigger system, with which the response of PVF2 to high velocity gas-fluid can be reliably measured, is also developed. The behavior of the diffluence system for a two stage light gas gun has been successfully observed by using this technique. The results show that actions of gas-fluid after diffluence on the target can be reduced rapidly to ten percent, and it will be sufficient for most experimental requirements if three diffluence plates are used.
