Multiple charge state ion beams are of special interest in the fields of atomic physics, material physics and other applications. Electron cyclotron resonance (ECR) ion source can produce high intensity ion beams of high charge state in cw or pulse mode.
For high-voltage applications the problem is the power consumption of devices, and as the room available in the high-voltage terminal of the...
The U400 cyclotron complex has been operated in the FLNR, JINR, since 1985. Currently, the complex is being prepared for reconstruction, which includes the modernization of the main nodes of the cyclotron, as well as the creation of a new system for transporting particles through channels leading to two main directions: to the SHELS installation and to the new experimental hall (NEH). In the...
The Electron String Ion Source (ESIS) is a type of ion source, which is under development since 1994, when the electron string phenomenon was first observed. ESIS is a sophisticated modification of Electron Beam Ion Source (EBIS) working in a reflex mode of operation under specific conditions, the operation is based on step-by-step ionization
of the ions by hitting with electrons of an...
The problem of erosion of the tungsten lining of the Tokamak reactor vacuum
chamber in contact with thermonuclear plasma is currently of serious interest. This
problem is particularly acute in the area of the Tokamak divertor, where the
greatest threat to the cladding elements is represented by intense pulsed thermal
loads resulting from rapid transients in the hot plasma of the Tokamak....
The Electron String Ion Source (ESIS) is type of ion source working in a reflex mode under specific conditions. The operation is based on step-by-step ionization of the ions by hitting with electrons of an electron string.
ESIS is a complex facility and ion trap control system is it's important part. It affects ion beam formation process and transfer to HILAC. The version, which is under...
JINR is developing novate cyclotron for proton therapy (including FLASH) for new JINR's international biomedical research center. The project is about to be put into manufacturing stage. As unavoidable parts of this process, engineering, mechanical and production limitations impose correction on the physical conceptual design of the cyclotron. Therefore, the initial extraction system should be...
Today, when developing and creating new accelerators of charged particles and heavy ions, various engineering and technological solutions are used in this area. The most important part of almost all accelerator complexes is the beam monitoring and diagnostics system. This work presents a system for monitoring charged particles and heavy ions, allowing operation in a wide range of energies of...
In gas phase experiments on the chemistry of superheavy elements at SHE Factory, nuclei recoiled from an irradiated target are separated from the beam and other by-products of nuclear reactions with a physical separator, focused in the focal plane and injected through a thin entrance window into a gas stopping chamber. Recoil nuclei, stopped in a gas mixture, are transported through a...
The study aimed to conduct dynamics calculations, considering collective effects in a storage ring for a compact monochromatic radiation source in the X-ray range based on Compton backscattering. The calculation focused on various instabilities and collective effects, including microwave instability, coherent synchrotron radiation (CSR), instability of transverse coupled modes, space charge,...
