Comparison of an Aluminum-Coated Phosphor Layer and a Channeltron Electron Multiplier Array as Extreme Ultraviolet-to-Visible Image Converters for Use in Space Applications.
Two types of image converter that produce visible from extreme ultraviolet (XUV) images are compared. One consists of a phosphor layer overcoated with aluminum, and the other is a Channeltron Electron Multiplier Array with a phosphor screen. All tests were conducted using a TV system because these converters are intended to be used in space applications where images are transmitted via closed circuit and telemetered TV systems. The advantages and disadvantages of each converter are discussed.
