The x-ray windows herein can have low gas permeability, low outgassing, high strength, low visible and infrared light transmission, high x-ray flux, low atomic number materials, corrosion resistance, high reliability, and low-cost. The x-ray window can include a film 11 with a polymer layer 22 and a graphite layer 21. The film 11 can consist essentially of graphite and polymer. Most of the film 11 can be the graphite layer 21. The polymer layer 22 can be a small portion of the film 11.

An X-ray tube includes: a vacuum housing configured to include an internal space which is vacuum; a target unit configured to be disposed in the internal space, and include a target that generates an X-ray by using an electron beam incident therein, and a target support unit that supports the target, the X-ray generated by the target being transmitted through the target support unit; an X-ray emission window configured to be so provided as to face the target support unit, and seal an opening of the vacuum housing, the X-rays transmitted through the target support unit being transmitted through the X-ray emission window; an elastic member configured to press the target unit in such a direction as to approach the X-ray emission window; and a target shift unit configured to shift the target unit pressed by the elastic member in a direction crossing an incidence direction of the electron beam.

Presented systems and methods facilitate efficient and effective generation and delivery of radiation. A radiation generation system can comprise: a particle beam gun, a high energy dissipation anode target (HEDAT); and a liquid anode control component. In some embodiments, the particle beam gun generates an electron beam. The HEDAT includes a solid anode portion (HEDAT-SAP) and a liquid anode portion (HEDAT-LAP) that are configured to receive the electron beam, absorb energy from the electron beam, generate a radiation beam, and dissipate heat. The radiation beam can include photons that can have radiation characteristics (e.g., X-ray wavelength, ionizing capability, etc.). The liquid anode control component can control a liquid anode flow to the HEDAT. The HEDAT-SAP and HEDAT-LAP can cooperatively operate in radiation generation and their configuration can be selected based upon contribution of respective HEDAT-SAP and the HEDAT-LAP characteristics to radiation generation.
