The purpose of this research is to develop high-power far-infrared light source in the terahertz frequency ranger and to promote its applications. The following progress and results have been achieved.1. Using repetitive pulsed power generator "ETIGO-IV" located in Nagaoka University of Technology, relativistic electron beam has been generated and analyzed for beam characteristics (brightness, pitch-factor, and divergence). After system optimization, the electron beam quality has met with the requirement for large-orbit gyrotron operation.2. Large-orbit gyrotron experiments have been carried out. The diagnostic results have shown electromagnetic radiation of nearly 150 GHz in frequency and TE_<14> mode.3. Three-dimensional numerical simulation has been used to analyze the interaction process of large-orbit gyrotron. The calculation results have helped in understanding the electron-beam behavior, resonant cavity design, and radiation mode control.4. Initial experimental study have been carried out at University of Fukui on large-orbit gyrotron applications, especially in plasma diagnostics and material analysis.

本研究的目的是开发太赫兹测距仪中的大功率远红外光源并推广其应用。取得了以下进展和成果： 1．使用位于长冈工业大学的重复脉冲功率发生器“ETIGO-IV”，生成相对论性电子束并分析其束特性（亮度、节距因子和发散度）。经过系统优化，电子束质量满足大轨道陀螺运行的要求。 2．大轨道回旋管实验已开展。诊断结果显示频率和TE_<14>模式的电磁辐射接近150GHz。 3．利用三维数值模拟分析了大轨道陀螺仪的相互作用过程。计算结果有助于理解电子束行为、谐振腔设计和辐射模式控制。4．福井大学已对大轨道回旋管应用进行了初步实验研究，特别是在等离子体诊断和材料分析方面。
