摘要： According to one embodiment, an apparatus includes a pyroelectric crystal, a deuterated or tritiated target, an ion source, and a common support coupled to the pyroelectric crystal, the deuterated or tritiated target, and the ion source. In another embodiment, a method includes producing a voltage of negative polarity on a surface of a deuterated or tritiated target in response to a temperature change of a pyroelectric crystal, pulsing a deuterium ion source to produce a deuterium ion beam, accelerating the deuterium ion beam to the deuterated or tritiated target to produce a neutron beam, and directing the ion beam onto the deuterated or tritiated target to make neutrons using a voltage of the pyroelectric crystal and/or an HGI surrounding the pyroelectric crystal. The directionality of the neutron beam is controlled by changing the accelerating voltage of the system. Other apparatuses and methods are presented as well.

摘要： A synchrocyclotron comprises a resonant circuit that includes electrodes having a gap therebetween across the magnetic field. An oscillating voltage input, having a variable amplitude and frequency determined by a programmable digital waveform generator generates an oscillating electric field across the gap. The synchrocyclotron can include a variable capacitor in circuit with the electrodes to vary the resonant frequency. The synchrocyclotron can further include an injection electrode and an extraction electrode having voltages controlled by the programmable digital waveform generator. The synchrocyclotron can further include a beam monitor. The synchrocyclotron can detect resonant conditions in the resonant circuit by measuring the voltage and or current in the resonant circuit, driven by the input voltage, and adjust the capacitance of the variable capacitor or the frequency of the input voltage to maintain the resonant conditions. The programmable waveform generator can adjust at least one of the oscillating voltage input, the voltage on the injection electrode and the voltage on the extraction electrode according to beam intensity and in response to changes in resonant conditions.

摘要： A proton acceleration system is provided for accelerating protons within a target. The system includes a laser source generating a laser beam having a wavelength λL and intensity and a target formed of foil having a selected thickness. The target is irradiated by the laser beam and transformed into a plasma that has a target density. This causes a treatment energy to be emitted from the foil due to the irradiation. The thickness of the foil of the target is selected so that the foil has a thickness within a range of optimal thickness Δs to 2×Δs, wherein Δs is less than the laser wavelength and is a function of the laser intensity, laser wavelength, and target density sufficient to achieve radiation pressure acceleration (RPA).

摘要： A perturbation device for a charged particle circulation system, capable of readily generating a distribution profile of a perturbation magnetic field, is provided. By partially superposing a perturbation magnetic field on a main magnetic field for circulating charged particles, perturbation is produced in trajectories of the charged particles. Then, the charged particles that have been injected into the charged particle circulation system are captured into a stable circular closed orbit. Using a leakage magnetic field formed of a magnetic field generated by magnetic field generation devices, each including a high-frequency coil, the perturbation magnetic field is generated.

摘要： The present invention is an RF cavity for accelerating electrons in imaging applications such as x-ray tubes and CT applications. An RF cavity having electron emitters placed therein accelerates the electrons across the cavity. The geometric shape of the cavity determines the electromagnetic modes that are employed for the acceleration of electrons. The fast electrons are used to generate x-rays by interacting with a target, either a solid or a liquid target. The electron accelerator may be used in an arc source for a stationary computed tomography application, in an x-ray tube, as a booster for an electron gun, and other imaging applications.

摘要： In an electron beam apparatus making use of an electron beam, a solenoid magnetic field generating section is disposed along an electron beam, and a cyclotron maser stimulating high-frequency resonator is provided within this magnetic field generating section. An emittance of the electron beam is adjusted by projecting a cyclotron maser stimulating high frequency wave in the same direction as or in the opposite direction to the traveling direction of the electron beam, and thereby a high-luminosity beam is generated.

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).
