3D target array for pulsed multi-sourced radiography
| DWPI Title: System for facilitating generation of x-rays and charged particle e.g. electron for use in radiography application, emits x-ray photon from apex in direction on-axis to axis which passes through apex |
| Abstract: The various technologies presented herein relate to the generation of x-rays and other charged particles. A plurality of disparate source materials can be combined on an array to facilitate fabrication of co-located mixed tips (point sources) which can be utilized to form a polychromatic cloud, e.g., a plurality of x-rays having a range of energies and or wavelengths, etc. The tips can be formed such that the x-rays are emitted in a direction different to other charged particles to facilitate clean x-ray sourcing. Particles, such as protons, can be directionally emitted to facilitate generation of neutrons at a secondary target. The various particles can be generated by interaction of a laser irradiating the array of tips. The tips can be incorporated into a plurality of 3D conical targets, the conical target sidewall(s) can be utilized to microfocus a portion of a laser beam onto the tip material. |
| Use: System for facilitating generation of x-rays and charged particle such as electron, photon, proton and neutron (all claimed) for use in radiography, airport security, crystallography, astronomy and spectroscopy applications. |
| Advantage: The operation cost of the laser is reduced, and the cost of the system for facilitating the generation of x-rays and charged particle is reduced. |
| Novelty: The system has one target that is provided with one tip material which forms a conical solid portion comprising an apex. The apex is joined to a perimeter of a base, by a lateral surface. A photon (141) in a laser beam is impinged upon the base, and is entered into one tip material to facilitate formation of x-ray photon (150) or one particle. The x-ray photon is emitted from the apex in a direction on-axis to an axis which is passed through the apex and about which the base is provided with a rotational symmetry. |
