A proton beam is produced at a velocity of the order of \({10}^{9} cm/s\) to interact with an uncharged hydrogen-boron medium such as \({H}_{3}B\) . The generated charged particles are confined by electromagnetic fields. This is the basic concept of the new non-thermal fusion reactor. An external electric field is applied to prevent the energy loss of the proton particles by friction, due to their interaction with the electrons of the medium, to keep the proton-boron fusion at a maximum cross-section. Alphas produced by \(p{B}^{11}\) fusion undergo nuclear elastic collisions with surrounding protons, triggering a \(p{B}^{11}\) CR. The aim of this paper is to estimate the key parameters related to the performance of a new fusion reactor with neutron-free fusion fuel \(p{B}^{11}\) considering the production of alpha particle avalanches by presenting only the main physical processes and not a complete engineering design. To achieve this goal, a conceptual fusion reactor is proposed in this work using laser-plasma interactions and magnetic confinement configurations. The final result of our work considering this new reactor shows that it is possible to achieve fusion energy gain about 115, which is much higher than other cases examined.
