Study of a dense hot plasma’s burning in Z-pinch devices with inertial-magnetic confinement

Abstract

The burning kinetics of dense hot plasma of composition D+D, D+T, D+ 3 He in devices with inertial-magnetic confinement concept is considered. Calculations of the burning kinetics of main fusion reactions in plasma with use of modern refined data on reaction rates at the appropriate temperatures and several types of energy loss for radiation have been made. An analysis of the energy yield is performed taking into account the change in plasma temperature and the heating of burning area in equilibrium plasma, which is described by Maxwell distribution, as well as the analysis of energy exchange between two adjacent burning volumes with different temperatures. Based on all the data found, estimates of the burning properties of plasma in thermonuclear devices with inertial-magnetic confinement of plasma have been made.

Clusterization and strong coupled-channels effects in deuteron interaction with 9Be nuclei

“…The transfer of the deuteron (dash-dotted curve) provides the dominant contribution in all the channels. Despite the fact that the spectroscopic amplitude of the deuteron S 1D3 = 0.558 in the 9 Be nucleus is not of great importance, a noticeable cross section is due to the large value of the deuteron spectroscopic amplitude S 1S1 = 1.732 of 4 He.…”

“…The current work is devoted to the investigation of the cluster structure of the 9 Be nucleus through Particle identification plots for the products of the d+ 9 Be reaction at 35 MeV incident energy: p, d, t, and 3,4 He. ∆E is the energy loss and Er is the residual energy.…”

“…Regarding nuclear technologies, 9 Be is a good wall material in thermonuclear devices [3,4]. For instance, for fusion-type devices a value of some dozens of percent of 9 Be is expected in the soft wall material [4].…”

Analysis of 9Be Fusion Cross Sections via a Simple Cluster Model

“…9 Be with low binding energy and cluster structure is an important nucleus in the field of nuclear physics. Also, it has a usage area in the field of nuclear technology like thermonuclear devices [11,12]. We first obtain the density distributions for α + α + n, d + 7 Li, 3 H + 6 Li, 3 He + 6 He and n + 8 Be cluster cases of the 9 Be nucleus.…”

“…In recent years, Aygun has proposed a simple cluster method, and has performed the elastic scattering calculations of 9 Li [6], 9 Be [7], 12 Be [8], 12 B [9] and 22 Ne [10] nuclei. He has gotten the results compatible with the experimental data.…”
