| 145 | LINEAR ACCELERATOR ACCELERATING MODULE TO SUPPRESS BACK-ACCELERATION OF FIELD-EMITTED PARTICLES | US15260101 | 2016-09-08 | US20170071054A1 | 2017-03-09 | Stephen V. Benson; Frank Marhauser; David R. Douglas; Lucas J. P. Ament |
| A method for the suppression of upstream-directed field emission in RF accelerators. The method is not restricted to a certain number of cavity cells, but requires similar operating field levels in all cavities to efficiently annihilate the once accumulated energy. Such a field balance is desirable to minimize dynamic RF losses, but not necessarily achievable in reality depending on individual cavity performance, such as early Q0-drop or quench field. The method enables a significant energy reduction for upstream-directed electrons within a relatively short distance. As a result of the suppression of upstream-directed field emission, electrons will impact surfaces at rather low energies leading to reduction of dark current and less issues with heating and damage of accelerator components as well as radiation levels including neutron generation and thus radio-activation. | ||||||

| 149 | METHOD AND SYSTEM OF BEAM INJECTION TO CHARGED PARTICLE STORAGE RING | US15033740 | 2013-11-07 | US20160255712A1 | 2016-09-01 | Hironari YAMADA |
| The charged particle storage system includes: a storage ring circulating, by a perturbating device, charged particles injected from outside; a power source supplying an electric current to the perturbating device; and a charged particle beam generating device. The charged particle beam generating device includes a DC accelerator that generates a constant voltage to accelerate electrons and thereby generates a beam of the electrons. While a current having its current intensity changing in a sinusoidal wave is caused to flow through the perturbating device continuously for at least 10 μs by a power source, an electron beam output from the charged particle beam generating device is injected to the storage ring continuously for at least 10 μs. Thus, a current larger than that stored by the conventional resonance injection method can be stored in the storage ring, and an X-ray having higher intensity can be generated. | ||||||

| The invention comprises a multi-field charged particle irradiation method and apparatus. Radiation is delivered through an entry point into the tumor and Bragg peak energy is targeted to a distal or far side of the tumor from an ingress point. Delivering Bragg peak energy to the distal side of the tumor from the ingress point is repeated from multiple rotational directions. Preferably, beam intensity is proportional to radiation dose delivery efficiency. Preferably, the charged particle therapy is timed to patient respiration via control of charged particle beam injection, acceleration, extraction, and/or targeting methods and apparatus. Optionally, multi-axis control of the charged particle beam is used simultaneously with the multi-field irradiation. Combined, the system allows multi-field and multi-axis charged particle irradiation of tumors yielding precise and accurate irradiation dosages to a tumor with distribution of harmful irradiation energy about the tumor. | ||||||
