Thin Windows for Gaseous and Liquid Targets: An Optimization Procedure
Many particle and nuclear physics experiments require cryogenic liquid, cryogenic high-pressure gas, or simply high-pressure gas targets with thin windows. Typically materials such as Havar,† Mylar,‡ Kapton,§ stainless steels, and various alloys of aluminum have been used. The most frequently used materials are Mylar and Kapton, which have relatively high tensile strengths and relatively low densities and atomic numbers. A comparison of the various materials on the basis of their performance as a target window, however, has not been available. In order that window design may be based on a complete understanding of the relationship between pressure and deflection an experimental program was carried out in two phases.
