ABSTRACT:
A thin-film window for a nuclear instrument comprising a frame ring, a thin film tightly stretched about the frame ring, a clamp ring for securing the thin film about the frame ring in a tightly stretched condition, and securing means such as a weld or glue, for securing the clamp ring to the frame ring. The thin-film window is manufactured by first preparing the frame ring and clamp ring by cleaning and removing stresses on the rings, cooling the frame ring to a temperature below that of the clamp ring, stretching a thin-film over the frame ring, clamping the clamp ring over the thin-film and frame ring while the film is stretched thereover, maintaining the clamp ring over the frame ring until they are at the same temperature, removing the excess film along the outside edges of the rings, and securing the rings together.
