Results obtained from an analysis of the energy spectrum of cosmic rays with energies in the region of E0 ≥ 1017 eV over the period of continuous observations from 1974 to 2017 are presented. A refined expression for estimating the primary-particle energy is used for individual events. This expression is derived from calculations aimed at determini...

AbstractElectron cyclotron heating is one of the methods of additional plasma heating and noninductive current drive in the T-15MD tokamak. One to eight gyrotrons with a total power up to 7 MW will be used. The frequency of the microwave used depends on the parameters of the experimental scenarios in which the heating will be used and on the physic...

AbstractThe metal surface erosion under powerful plasma pulse flows typical of transient processes in tokamaks, ELMs, and plasma disruptions and simulated on a quasistationary plasma accelerator (QSPA) is studied. The hillock relief formation on the molten metal surface over which the plasma flow parallel to the surface moves and also the formation...

AbstractA neutron collimator is developed to attenuate the neutron flux and reduce the residual induced activity in the interportal space of the diagnostic system of neutral particle analyzers of the ITER tokamak reactor. The collimator is installed in the port plug of the ITER vacuum vessel in front of an inlet to the vacuum pipeline of the diagno...

AbstractResults of the complex experimental research of plasma impact on fusion reactor materials are presented. The near-wall plasma of a tokamak reactor is simulated on the linear plasma device LENTA (National Research Center Kurchatov Institute). Plasma fluence of 1022–1023 cm–2 to the material surface is provided at 1012–1013 cm–3 of plasma den...

AbstractPlasma-chemical deposition of a protective coating on the first wall of a fusion device using a chemically active gas (precursor) remains to date one of the primary ways to protect the plasma against cooling impurities. This method has proved effective and does not require the use of additional and expensive equipment. The process in which ...

AbstractThe work presents some simulation results of discharge scenarios at the KTM facility during the autumn campaign 2019. The parameters for providing the plasma breakdown phase of the tokamak are estimated. The experimental data of plasma discharges in the KTM are confirmed by the numerical simulation results. The discharge 3669 is simulated i...

AbstractCharacteristic regularities of development of thermoelectrodynamic processes in current-carrying elements of superconducting magnet systems are discussed. It is shown that, under certain conditions, the process of penetration of a magnetic flux can acquire an avalanche-like character, much like the development of a chain reaction of neutron...

AbstractThe passage of probing beams of the submillimeter range in the T-15MD tokamak chamber along various chords is considered in this paper. Microwave generators with submillimeter radiation and HCN lasers with a radiation wavelength of λ = 337 μm are widely used in interferometers in many plasma systems as sources of probing beams. The possibil...
