Paper Abstract

A white light interferometric system for remote monitoring of the expansion of a pressured foil membrane is described. The membrane will serve as a transmission "window" in liquid and gaseous target chambers for the production of radio-isotopes in an accelerator. Alternative commercial solutions are unsuitable in this environment. We describe some feasibility experiments which have been performed on a model cell pressurized to expand the foil. Pressures of up to 25 bar induce expansions of up to 1.5 mm in the center of the foil, which the optical probe, positioned 100 mm away, detects with a precision of 20 μm. The results fit well to an accepted model, yielding also the Young's modulus of the foil and its transition from elastic to plastic behavior.
