Breakeven Conditions for Beam-Target Fusion with Electron-Suppressed Targets

TL;DR

This paper analyzes the conditions under which beam-target nuclear fusion can achieve breakeven, focusing on electron-suppressed targets and deriving energy-based criteria for net energy gain.

Contribution

It introduces a self-consistent model of stopping power in electron-suppressed targets and establishes quantitative conditions for fusion breakeven distinct from plasma methods.

Findings

Derived implementation-agnostic breakeven conditions.

Formulated a self-consistent stopping power model.

Extended analysis of beam-target fusion energy balance.

Abstract

This manuscript provides a detailed and extended analysis of the breakeven conditions for nuclear fusion based on beam-target interactions, distinct from conventional plasma-based approaches. Building on the energy-based criterion introduced in the accompanying Letter~\cite{TK_arXiv}, we formulate a self-consistent description of stopping power in electron-suppressed targets and derive quantitative, implementation-agnostic conditions under which fusion energy generation can exceed beam energy loss.
