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.

本课题的研究目的是开发太赫兹波段的大功率远红外光源，并促进其应用。取得了以下进展和成果：利用位于长冈工业大学的重复脉冲功率发生器“ETIGO-IV”，产生了相对论电子束，并分析了光束特性（亮度、间距因子和发散度）。系统优化后，电子束质量满足大轨道回旋管运行的要求。进行了大轨道回旋加速器实验。诊断结果显示电磁辐射频率接近150 GHz， TE_<14>模式。采用三维数值模拟方法对大轨道回旋管相互作用过程进行了分析。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。福井大学已经对大轨道回旋加速器的应用进行了初步的实验研究，特别是在等离子体诊断和材料分析方面。
