Abstract: A radiotherapy system includes an X-ray target configured to convert an incident electron beam into a therapeutic X-ray beam, a purging magnet configured to redirect unwanted particles emitted from the X-ray target away from the therapeutic X-ray beam, and a particle collector configured to absorb the unwanted particles subsequent to redirection by the purging magnet. The particle collector may be configured to dissipate at least 50% of the energy of the incident electron beam.

Abstract: Systems and techniques may be used for determining a line segment to be delivered from a particle beam towards a target. An example technique may include continuously scanning the particle beam at a constant rate from a starting point to an ending point, and determining a plurality of spots located between the starting point and the ending point. The technique may include determining a plurality of beamlets based on the plurality of spots, and determining, using an amount of dose to be delivered via each beamlet, a total amount of dose to be delivered. The technique may include generating a line segment having the starting point and the ending point, the line segment having the total amount of dose to be delivered based on the plurality of beamlets.

CPC classification number: G21K1/093

Abstract: A quantum illumination apparatus includes an ion trap in a cryogenic cooler. The ion trap uses electric and magnetic fields to trap an ion and the quantum illumination apparatus uses the trapped ion to produce a signal photon for use in quantum illumination. The signal photon has correlations with an idler field stored with use of the trapped ion, as a phonon of the trapped ion. A signal photon transmission line extends between the ion trap and an antenna. The signal photon may be scattered, e.g., reflected or refracted, by a target object back to the antenna, and the transmission line transmits the signal photon back to the ion trap. The ion trap generates an electrical signal based on correlations between the signal photon and the idler field. The quantum illumination apparatus is arranged to detect reception of the signal photon based on this generated electrical signal.

Abstract: The invention comprises a method and apparatus for tuning a charged particle beam path of a charged particle beam system used to treat a tumor of a patient, comprising the steps of: positioning a two-dimensional charged particle detector in a beam line downstream from a magnet pair; operating windings of the magnet pair at a first power level to generate a first magnetic field; measuring a beam position with the first two-dimensional charged particle detector; adjusting a correction magnetic field by driving voltage of a correction coil at a second power level, the second power level less than five percent of the first power level, where the first magnetic field and the correction magnetic field combine to yield an operational magnetic field; and the steps of measuring and adjusting the correction magnetic field changing the operational magnetic field to adjust a measured beam position toward a target beam position.

Abstract: Systems and methods relate to arranging atoms into 1D and/or 2D arrays; exciting the atoms into Rydberg states and evolving the array of atoms, for example, using laser manipulation techniques and high-fidelity laser systems described herein; and observing the resulting final state. In addition, refinements can be made, such as providing high fidelity and coherent control of the assembled array of atoms. Exemplary problems can be solved using the systems and methods for arrangement and control of atoms.

Abstract: A scintillation material is longitudinally packaged in a circumferentially surrounding sheath, where the sheath has a lower index of refraction than the scintillation material, to form a scintillation optic or scintillation fiber optic. The scintillation material yields secondary photons upon passage of a charged particle beam, such as a positively charged residual particle beam having transmitted through a sample. The internally generated secondary photons within the sheath are guided to a detector element by the difference in index of refraction. Multiple scintillation optics are assembled to form a two-dimensional scintillation array coupled to a two-dimensional detector array, such as for use in determination of state of the residual charged particle beam, determination of an exit point of the particle beam from the sample, path of the treatment beam, and/or tomographic imaging.
