Abstract : (U) This report is the culmination of a series of small projects from fiscal years 2011 through 2014. These projects sought a material that not only exhibited a measureable effect when dosed with X-rays (5 seconds using 80 to100 kilovolts [kV], 5 milliamperes [mA], tungsten [W] target) but could also withstand temperature extremes encountered during processing and potential application. (U) The result of these efforts was a composite material that would hold a quasi-permanent electric charge and rapidly discharge the electric charge upon X-ray exposure. The composite material combined the properties of an electret and an X-ray photoconductor, with a measurable charge maintained for at least a period of hours and an X-ray response occurring within an increment of time that depended upon incident X-ray power.
