Emitter of Electrons and Ions for Industrial and Research Accelerators
نویسندگان
چکیده
The distinguishing features of the new type of unheated liquid metal field emitter are reported. The emitter is based on track membrane technology and therefore its surface cam be made as large as necessary. It is cheap in construction, fabrication and exploitation. The emitter can be operated indefinitely long time in field emission, explosive emission or ion emission mode by poor vacuum up to 10 Torr without noticeable change of emission characteristics.

Electron curtain accelerator is a type of low-energy electron accelerator, which plays an important role in many different industries such as printing, coating and packing to promote product quality, while reducing volatile organic compounds for protecting global environment. Electron emitter is one of the main components of this type of accelerators. Multi-filament cathodes and grid structures...
متن کاملApplications of pyroelectric particle accelerators
The discovery of pyroelectric X-ray generation in 1992 by Brownridge has led to a recent surge of interest in the use of the pyroelectric effect as a means of producing useful radiation. By heating or cooling a pyroelectric crystal such as lithium tantalate (LiTaO3) in a vacuum, a potential on the order of 100 kV can be generated. This potential is great enough to eject electrons from the cryst...

Introduction: Now day Ionizing radiation has found increasing applications in cancer treatment. However, in the treatment different kinds and size of tumors especially metastatic and small size tumors, conventional methods of external radiation therapy are not common. In radionuclide therapy, the use of monoclonal antibodies has made it possible to achieve maximum dose to small size tumor and m...
متن کاملThe Temperature and Mass Effects on Dust Grain Electrical Potential in Dusty Plasma
By orbit-limited motion (OLM) theory and the kinetic model, currents carried by electronsand ions on the dust grain are obtained and the effects of temperature and drift velocity of ions on thedust grain electrical potential are considered. The calculations were performed for finding the role of densities of dust grains and ions on the dust grain electrical potential which is the ma...
