Abstract: A method for forming an optimized radiation shield design for a component including providing a computer system programmed to generate data files that define a component radiation shield having an optimized design based on pre-stored data defining particular radiation characteristics and user-provided data defining radiation shield design criteria. Radiation shield design criteria are inputted into the computer system which processes the inputted radiation shield design criteria and the pre-stored data defining particular radiation characteristics in order to generate data files defining an optimized design for a component radiation shield. The generated data files defining the optimized design for a component radiation shield are provided to a metallic three-dimensional printing system. The three-dimensional printing system is then activated to form a component radiation shield using a predetermined metal powder and the generated data files that define the optimized component radiation shield design.

Abstract: A miniaturized high-speed modulated X-ray source (MXS) device and a method for rapidly and arbitrarily varying with time the output X-ray photon intensities and energies. The MXS device includes an ultraviolet emitter that emits ultraviolet light, a photocathode operably coupled to the ultraviolet light-emitting diode that emits electrons, an electron multiplier operably coupled to the photocathode that multiplies incident electrons, and an anode operably coupled to the electron multiplier that is configured to produce X-rays. The method for modulating MXS includes modulating an intensity of an ultraviolet emitter to emit ultraviolet light, generating electrons in response to the ultraviolet light, multiplying the electrons to become more electrons, and producing X-rays by an anode that includes a target material configured to produce X-rays in response to impact of the more electrons.
