Systems for directing a pulsed beam of charged particles include an ion source configured to produce a pulsed ion beam that includes at least one ion bunch. Such systems include an electromagnet for producing an electromagnetic field through which the pulsed ion beam travels, and an automated switch that selectively activates the electromagnet. A source of radiation triggers the automated switch, and at least one processor is configured to activate the electromagnet as the ion bunch traverses the electromagnetic field. Such systems may be useful, for example, for filtering a pulsed ion beam to select ions falling within a desired energy range and/or for providing pulsed ion radiation at desired times.

Systems and methods for directing an ion beam using electromagnets

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.

Systems and methods for providing an ion beam

Laser accelerated Proton beams provides compact sources for Proton beams. This invention describes several examples of optic designs which provide a compact beam delivery system capable of supporting pencil beam scanning and delivering the required clinical dosage in a tight beam spot.

Beam delivery system for proton therapy for laser-accelerated protons

Systems for treating a patient using protons include a proton source configured to provide a proton beam having a plurality of proton energies and at least one processor. The at least one processor is configured to control relative movement between the proton beam and the patient in two dimensions, and to control the proton energy distribution to adjust the penetration depth of the protons in the third dimension while maintaining substantially fixed coordinates in the other two dimensions. Such treatment systems allow for shorter treatment times, higher patient throughput, more precise treatment of the desired areas, and less collateral damage to healthy tissue.

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. At least one processor is configured to control the source of the electromagnetic radiation and the optics to alter the energy, polarization, spatial profile, and/or the temporal profile of the electromagnetic radiation beam, and to adjust the flux and/or energy of the proton beam. In some instances the system may adjust the proton beam energy while holding the proton beam flux substantially constant, or alternatively adjust the proton beam flux while holding the proton beam energy substantially constant. In other instances the system may adjust the proton beam energy while varying the proton beam flux, and/or adjust the proton beam flux while varying the proton beam energy.

The present invention discloses a system and method for generating a beam of fast ions. The system comprising: a target substrate having a patterned surface, a pattern comprising nanoscale pattern features oriented substantially uniformly along a common axis; and; a beam unit adapted for receiving a high power coherent electromagnetic radiation beam and providing an electromagnetic radiation beam having a main pulse and a pre-pulse and focusing it onto said patterned surface of the target substrate to cause interaction between said radiation beam and said substrate enabling creation of fast ions.

System for fast ions generation and a method thereof

A system for generating pulses of charged particles, comprising a high intensity pulsed laser emitting laser pulses which, when impacting a target, generate pulses of charged particles. The particles passes through an electromagnet energized by a low inductance current feed incorporating a light activated switch to turn the energizing current on and off. Part of the light of the laser pulse is directed onto the light activated switch, such that the magnetic field is optically synchronized with the generated pulses of charged particles. This enables energizing the magnet only during passage of the pulses, such that it is lighter and more energy efficient than prior art systems using CW electromagnets. Synchronization also enables selection of charged particles having a predetermined range of particle energy, by timing activation of the magnetic field such that it diverts onto a selected beam path only the particles having the predetermined range of energies.
