    Abstract: 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.
