ИНЖЕКТОР ПУЧКА НЕЙТРАЛЬНЫХ ЧАСТИЦ НА ОСНОВЕ ОТРИЦАТЕЛЬНЫХ ИОНОВ

FIELD: physics. SUBSTANCE: neutral particle beam injector based on the negative ions, containing an ion source, an accelerator and a converter in order to generate a beam of the neutral particles approximately of 5 MW with energy of approximately 0.50-1.0 MeV. Ions, generated by the ion source, are accelerated to the pre-injection at high energy accelarator by the electrostatic preaccelerator based on the multiaperture mesh that is used to draw the ion beams from the plasma and to accelerate to some fraction of the desired beam energy. A beam from the ion source passes through a pair of the deflecting magnets that provides the ability of the beam to move along the axis before entering the high energy accelerator. After acceleration to full energy, the beam enters the converter, wherein it is partially converted into a beam of the neutral particles. The remaining types of ions are separated by the magnet and sent to the electrostatic energy converters. The neutral particle beam passes through the check valve and enters the plasma chamber. EFFECT: increased productivity of the neutral particle beam forming. 23 cl, 18 dwg, 1 tbl РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 619 923 C2 (51) МПК G21K 1/00 (2006.01) H05H 3/02 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ФОРМУЛА (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ 2012137795, 04.09.2012 (24) Дата начала отсчета срока действия патента: 04.09.2012 Дата регистрации: Приоритет(ы): (22) Дата подачи заявки: 04.09.2012 (43) Дата публикации заявки: 10.03.2014 Бюл. № 7 2 6 1 9 9 2 3 R U (73) Патентообладатель(и): ТРАЙ АЛЬФА ЭНЕРДЖИ, ИНК.

ЭЛЕКТРОСТАТИЧЕСКИЙ ИНЖЕКТОР ЧАСТИЦ ДЛЯ ВЫСОКОЧАСТОТНОГО УСКОРИТЕЛЯ ЗАРЯЖЕННЫХ ЧАСТИЦ

Изобретение относится к области ускорительной техники. На входе первого объемного резонатора предусмотрен электрод, который подключен к источнику постоянного напряжения и на основе которого формируется потенциальная яма, которая обуславливает ускорение частиц, испускаемых источником ионов, к первому объемному резонатору. За счет того что источник ионов и ускорительный участок, то есть объемные резонаторы ускорительного участка, находятся на общем потенциале, в частности потенциале земли, достигается то, что электростатическая потенциальная яма не вносит вклад в полную энергию частиц, полный эффект ускорения достигается за счет индукции напряжения в ВЧ резонаторе, и источник постоянного напряжения не нагружается током пучка, так что он не должен быть точно регулируемым или высокопроизводительным.

A PROTON LINEAR ACCELERATOR SYSTEM FOR IRRADIATING TISSUE WITH TWO OR MORE RF SOURCES

Proton beams are a promising alternative to X-rays for therapeutic purposes because they may also destroy cancer cells, but with a greatly reduced damage to healthy tissue. The energy dose in tissue may be concentrated at the tumor site by configuring the beam to position the Bragg Peak proximate the tumor. The longitudinal range of a proton beam in tissue is generally dependent upon the energy of the beam.

Anion-based neutral beam injector

Negative ion-based neutral beam injector

A negative ion-based neutral beam injector comprising a negative ion source, accelerator and neutralizer to produce about a 5 MW neutral beam with energy of about 0.50 to 1.0 MeV. The ions produced by the ion source are pre-accelerated before injection into a high energy accelerator by an electrostatic multi-aperture grid pre-accelerator, which is used to extract ion beams from the plasma and accelerate to some fraction of the required beam energy. The beam from the ion source passes through a pair of deflecting magnets, which enable the beam to shift off axis before entering the high energy accelerator. After acceleration to full energy, the beam enters the neutralizer where it is partially converted into a neutral beam. The remaining ion species are separated by a magnet and directed into electrostatic energy converters. The neutral beam passes through a gate valve and enters a plasma chamber.
