Laser-driven Cyclotron Autoresonance Accelerator*
Theory is developed for the cyclotron autoresonance acceleration of electrons in a gently-focused Gaussian laser beam and a gently tapered axial magnetic field. Numerical simulation shows, for example, acceleration from 50 MeV to 178 MeV over a distance of 148 cm, using a 10.6 μm CO2 laser with a minimum spot size of 0.1 cm.
متن کاملProton Accelerator Development in China
The China Spallation Neutron Source (CSNS) and the Chinese Accelerator Driven Systems (C-ADS) projects are both underway in China. The CSNS includes a 100 kW RCS accelerator and first beam on target is planned for 2017. The C-ADS project includes a high power superconducting linac with a low energy (25-50 MeV) initial stage by 2015 and higher power deployment later. In addition to these intense...
متن کاملPROTON RADIOGRAPHY EXPERIMENT BASED ON A 100 MeV PROTON CYCLOTRON*
A proof-of-principle test-stand for proton radiography is under construction at China Institute of Atomic Energy (CIAE). This test-stand will utilize the 100 MeV proton beam provided by the compact cyclotron CYCIAE-100, which has been built in the year of 2014, to radiograph thin static objects. The assembling of the test-stand components is finished by now. We will carry out the first proton r...
متن کاملCyclotron versus Synchrotron for Proton Beam Therapy
Two categories in the beam delivery system of proton therapy, scattering and scanning, are closely related to the temporal beam structure, in turn, type of accelerators. Since the synchrotron is well matured technically, efficient and dependable routine operation will be achieved if it is combined with a scatterer system. \Vhen more sophisticated scanning system is sought for better dose distri...
متن کاملA Compact Permanent Magnet Cyclotron for Accelerator Mass Spectrometry
We describe the development of a Cyclotron Mass Spectrometer (CMS) for the detection of trace amounts of rare isotopes. A compact low energy cyclotron optimized for high mass resolution has been designed and fabricated. The CMS has high sensitivity and is designed to measure 14C at abundances of 10-12. A novel feature of the CMS is the use of permanent magnets to energize the 30 cm diameter iro...
