Title: THE OPTICAL COUPLING OF A SCINTILLATION CHAMBER TO AN IMAGE-INTENSIFYING TUBE

Abstract

Several methods for coupling a fiber scintillation chamber to an image- intensifying tube are considered. A high-speed lens was designed to image the ends of a curved fiber bundle on the curved cathcde of an image-intensifying tube. The lens covers a 5-in. field at one-to-one magnification. and at a speed of f/ 1.5. The details of this lens design and its expected performance are discussed. The results of a series of experiments on plastic scintillating fibers were used to determine that the internal reflectivity is 0.993 and absorption constant is 0.015 cm/sup -1/ in the fiber. The data were then used to compute the optical properties of fibers appropriate to a scintillation chamber system. Certain other optical properties of the components were estimated so that three possible optical coupling schemes could be compared in detail. They are: the lens alone, a glass fiber bundle alone, and a combination of the lens and a glass fiber bundle. The lens alone is about half as efficient as either of the other two methods. The numerical aperture and probable transmission properties of each system are outlined. (auth)
