Utilizing the effective interaction potentials to investigate the hot thermal relaxation induced via ion and electron temperature of DT, D3He and P11B hot plasma

Abstract

In this work, the binary model and the effective interaction potentials approach are used to investigate the hot thermal relaxation induced by the temperature of dense plasma. This model is significant for thermonuclear combustion, especially for non-isothermal dense hot plasma fuels such as DT (neutron generator). Therefore, we used the development of this model for the first time to physically describe two neutron-free fuels D³He and P¹¹B. In this study, we examine the temperatures of electrons (Te) and ions (Ti) individually because the temperature within the electron and ion subsystems attains equilibrium much more rapidly than the temperature between electrons and ions. This phenomenon arises from the disparity between the masses of ions and electrons. Since the simulations and computations for fusion through confinement are exceedingly intricate due to the multitude of different physical processes that occur, and a considerable amount of time is required to perform these calculations, we have applied the method of effective interaction potentials for the first time in this study as this method can facilitate precise and rapid calculations for dense plasmas. The effective interaction potentials consist of two components: a) charge overlap effects at extended distances and b) quantum effects at shorter distances. We compute the stopping power, deceleration time, transfer coefficients, energy absorption, and temperature relaxation associated with non-isothermal dense hot plasma of DT, D³He, and P¹¹B fuels, identifying their optimal values.
