摘要： A collision reaction pool ion acceleration apparatus which has extremely low crosstalk. The apparatus comprises an apparatus body, a vacuum chamber, a first tube bundle channel and a second tube bundle channel. The vacuum chamber is fixedly connected to the interior of the apparatus body; the other end of the interior of the apparatus body is fixedly connected to a first insulation seat. A collision chamber is embeddedly connected to the inside the first insulation seat, and a high-frequency electrode quadrupole lens is fixedly connected to two sides of the collision chamber. When charged ions enter the collision chamber, the high-frequency electrode quadrupole lens focuses on the charged ions, so that the incoming charged ions form a new motion trajectory in the collision chamber, and the charged ions are easily separated from the collision chamber, thereby increasing the working efficiency.

摘要： A method for providing an ensemble of beamlets effectively acting as a high-energy laser pulse is disclosed. According to the method, a beamlet pattern with a plurality of spatially distributed laser beamlets is provided. The beamlets are spread in time by introducing a different temporal delay to each of the beamlets. The beamlets are spectrally broadened. The beamlets are incoherently combined in space and time to provide the ensemble of beamlets. Also disclosed is a method for accelerating charged particles. Further disclosed is an optical arrangement for providing an ensemble of beamlets effectively acting as a high-energy laser pulse. The optical arrangement comprises a beamlet generating device providing a beamlet pattern of spatially distributed laser beamlets, a step optic for spreading the spatially distributed laser beamlets in time, a spectral broadening device, and a combining device for incoherently combining the spectrally broadened beamlets in space and time to provide the ensemble of beamlets. Additionally disclosed is a laser-plasma accelerator comprising the optical arrangement.

摘要： A system is provided for accelerating charged particles and producing high energy photons. The system includes a nanostructure comprising at least one tube having a hollow core channel surrounded by a wall of a nanomaterial, e.g., comprising wall electrons and ions. The nanostructure is configured to interact with a beam of charged particle having a quasi-solid beam density, e.g., greater than 1018 cm−3. The beam of charged particles gains energy or momentum at an average acceleration gradient, e.g., greater than 1 TeraVolt (TeV) per meter along a longitudinal direction, and undergoes focusing in a transverse direction to increase the density of the beam of the charged particles, e.g. by at least an order of magnitude.

摘要： Provided is a variable energy and miniaturized accelerator. It is impossible to change the energy of the extraction beam in the related cyclotron or to miniaturize an accelerator in the related synchrotron. The accelerator includes a pair of magnets which form a magnetic field therebetween; an ion source which injects ions between the magnets; an acceleration electrode which accelerates the ions; and a beam extraction path which extracts the ions to the outside. A plurality of ring-shaped beam closed orbits formed by the pair of magnets, in which the ions of different energies respectively circulate, are aggregated on one side. The frequency of the radiofrequency electric field fed to the ions by the acceleration electrode is modulated by the beam closed orbits.

摘要： An apparatus for guiding, in particular directing or accelerating, charged particles (50), comprising: a substrate (110) having a surface (115); an optically thinner layer (120) formed on the surface (115); an inhomogeneous channel (130) which is formed by two mutually opposite delimiting structures on a side of the layer (120) that is opposite the substrate (110); and a radiation device which is designed to generate at least one pulsed laser beam (140) and inject the at least one pulsed laser beam (140) into the channel (130) from a side that is opposite the optically thinner layer (120). The layer (120) for the laser beam (140) is optically thin, and the delimiting structures have a high optical density in comparison with the layer (120). The delimiting structures are designed to guide the particles (50) by means of the laser beam (140) in the channel (130) and alternatingly focus them along the channel (130) and in at least one direction perpendicular to the channel (130).

摘要： Methods and systems are disclosed for using a chromatic lens system to provide a “flying focus”—i.e., an advanced focusing scheme enabling spatiotemporal control of a focal location. In a method, a photon beam is emitted from a source at a wavelength. The photon beam may have more than one wavelength. The photon beam is focused to a focal location using a chromatic lens system. The focal location is at a first longitudinal distance along an optical axis from the chromatic lens system. The wavelength of the photon beam is changed as a function of time to change the focal location as a function of time. The wavelength may be changed such that the focal location changes with a focal velocity.

摘要： Systems for generating a proton beam include an electromagnetic radiation beam (e.g., a laser) that is directed onto an ion-generating target by optics to form the proton beam. A detector is configured to measure a laser-target interaction property, which a processor uses to produce a feedback signal that can be used to alter the proton beam by adjusting the source of the electromagnetic radiation beam, the optics, or a relative position or orientation of the electromagnetic radiation beam to the ion-generating target. By adjusting the laser-target interaction, the feedback can be used to control properties of the proton beam, such as the proton beam energy or flux. Such systems have certain advantages, including reducing the size, complexity, and cost of machines used to generate proton beams, while also improving their speed, precision, and configurability.
