摘要： A particle therapy system capable of measuring energy of a charged particle beam even during irradiation of the charged particle beam is provided. A beam delivery (irradiation) system comprises a block collimator constituted by a pair of collimator members, and an energy detector mounted to one of the collimator members to be disposed on the upstream side thereof. When the pair of collimator members are moved in directions away from each other, a beam passage is formed between them. The energy detector constitutes an energy measuring device together with a signal processing unit. A part of the ion beam having reached the interior of the irradiation nozzle is irradiated to a patient through the beam passage. When a part of the remaining ion beam enters the energy detector, electric charges generate in the energy detector. The signal processing unit determines energy of the ion beam based on a position within the energy detector at which electric charges have generated in maximum amount.

摘要： An electron storage ring has bending magnets, quadrupole magnets, and sextupole magnets arranged in a ring for constraining a beam of electrons along a path. When the beam is injected, a control means controls a power source for the magnet so that the beam has a high equilibrium emittance. This gives the beam a large dynamic aperture, simplifying beam injection. Once the beam has been injected, the field strengths of the magnets are varied to cause a reduction in the emittance to a low value, at which the beam is stored. Synchrotron radiation is generated which has a high brightness because the low emittance means the beam has a small diameter. During the reduction in equilibrium emittance, the betatron oscillation frequency is maintained on a stable operation region and the chromaticity is maintained substantially zero.

摘要： In a bending magnet, a core which is substantially sectoral or semi-circular in horizontally sectional configuration and in which opposed magnetic poles are formed and a vacuum chamber for storage of a charged particle beam is disposed in a gap between the opposed magnetic poles, and a pair of upper and lower exciting coils for generating a bending magnetic field in the gap between the magnetic poles of core, the reluctance against the magnetic flux passing through a portion of the core adjacent to the inner circumference of the orbit of the charged particle beam and a portion of the core adjacent to the outer circumference of the charged particle beam orbit is equally uniformed over the overall length of the orbit of the charged particle beam. With this construction, the magnetic flux density becomes uniform in the gap between magnetic poles where the magnetic flux passing through the inner and outer circumference side portions is concentrated and the magnetic flux distribution is uniformed in the orbital direction in the gap, thereby eliminating adverse influence upon the charged particle beam, and the bending magnet can be very effective for use in a synchrotron or a storage ring.

摘要： A particle beam irradiation system which can increase an availability factor. An ion beam extracted from one proton beam linac is bent at 90 degrees by a switching magnet and is introduced to RI production equipment through a beam line. In the RI production equipment, a RI is produced using the introduced ion beam. An ion beam extracted from the other proton beam linac is bent at 90 degrees by the switching magnet and is introduced to a synchrotron through a beam line. The ion beam extracted from the synchrotron is irradiated to a patient from irradiation equipment. If one proton beam linac comes into an abnormal state, the one proton beam linac is stopped in operation and checked. During the check, the ion beam extracted from the other proton beam linac is selectively introduced to the RI production equipment and the synchrotron by the switching magnet.

摘要： An industrial compact synchrotron radiation source which can improve vacuum evacuation performance to prolong life-time of a charged particle beam and supply highly intensive stable synchrotron radiation. In the source, a charged particle beam bending duct forming a vacuum chamber through which the charged particle beam circulates is encompassed by a bending electromagnet, and at least one SR guide duct for guiding the radiation to outside extends from the outer circumferential wall of the bending duct. The SR guide duct is connected through a gate valve to an SR beam line duct for guiding the SR beam to an object to be worked and a vacuum pump is disposed on the side, close to an orbit of the charged particle beam, of the gate valve. The SR guide duct extending from the outer circumferential wall of the bending duct takes a form of a divergent duct which is widened in accordance with a spreading angle of the SR beam traveling through the SR guide duct.
