“…Simulation results imply that FRC plasma targets with an initial plasma density approximately greater than 1× 10 18 cm −3 can be compressed and heated effectively to the ignition condition. Until now, the maximum plasma density obtained in experiments is 5×10 16 cm −3 known from the reported works on the FRX-L device [10,25,26]. The maximum density of FRC plasma targets formatted at Yingguang-I facility is about 1×10 16 cm −3 .…”

“…One of great importance is that the charged products from fusion reactions themselves transfer the thermonuclear energy to the DT plasmas while the thermonuclear burning wave propagates in magnetized plasma target [12][13][14][15][16]. In addition, the compressed magnetic field can confine charged products and enhance their energy deposition to the plasma.…”

Study on the compression of field-reversed configuration (FRC) by a magnetic-driven solid liner is carried out based on a one-dimensional code. In the investigation, plasma self-heating effect by alpha particles is taken into account. Numerical results show that the self-heating of alpha particles to DT plasma mainly occurs in the vicinity of O-point of the FRC target. The plasma ignition region is divided into two parts: the low-density ignition region near the central axis and the high-density ignition region in the O-point area. Before FRC plasma target expansion, the energy of alpha particles is well confined nearby the O-point by compressed magnetics. The DT plasma volume burning exists in a short time (approximately 0.1 ms) after a maximum convergence ratio of solid liner and the compressed strong magnetic field degrades the propagation of FRC plasma burning.

“…Another important issue not addressed in this article is the finite cylinder length in realistic target configurations. Depending on a specific target design, the cylindrical section analysed in this work may only be an initiating (ignition) part of a more complex configuration (a possible scheme of such a cylindrical target that might be relevant to inertial fusion energy is given in Refs [5][6][7]). Clearly, the results of the present work will be applicable only when the length of the ignition section is large compared with its radius.…”

Ignition conditions for magnetized target fusion in cylindrical geometry

Abstract. Ignition conditions in axially magnetized cylindrical targets are investigated by examining the thermal balance of assembled DT fuel configurations at stagnation. Special care is taken to adequately evaluate the energy fraction of 3.5 MeV alpha particles deposited in magnetized DT cylinders. A detailed analysis of the ignition boundaries in the ρR, T parametric plane is presented. It is shown that the fuel magnetization allows a significant reduction of the ρR ignition threshold only when the condition BR ² 6 × 10 5 G cm is fulfilled (B is the magnetic field strength and R is the fuel radius).

In connection with fundamental issues relevant to magnetized target fusion, the distribution function of thermonuclear alpha particles produced in situ in a dense, hot, and strongly magnetized hydrogenic plasma considered fully ionized in a cylindrical geometry is investigated. The latter is assumed in local thermodynamic equilibrium with Maxwellian charged particles. The approach is based on the Fokker–Planck equation with isotropic source S and loss s terms, which may be taken arbitrarily under the proviso that they remain compatible with a steady state. A novel and general expression is then proposed for the isotropic and stationary distribution f(v). Its time-dependent extension is worked out numerically. The solutions are valid for any particle velocity v and plasma temperature T. Higher order magnetic and collisional corrections are also obtained for electron gyroradius larger than Debye length. f(v) moments provide particle diffusion coefficient and heat thermal conductivity. Their scaling on collision time departs from Braginski’s.
