Introduction of new materials and designs have allowed production of an improved low energy Xray transmission window. These changes have allowed improvement in the x-ray acceptance angle, the open area percentage and the x-ray transmission. The new window is built using low Z materials for the support structure and film. The x-ray window can tolerate well over 1 atmosphere of forward pressure. The window is shown to be resistant to corrosion from humidity and temperature. The window is high vacuum compatible and can tolerate vacuum bake out temperatures.
