Abstract

With rapid advances in THz devices, the human exposure to THz waves increases, necessitating thorough safety assessment before commercialization. Despite the significance of frequencies such as 600 GHz in next-generation technologies, currently, no gyrotron is specifically designed for exposure experiments at such high frequencies. Therefore, we developed a 600-GHz continuous wave (CW) gyrotron with a Gaussian beam output to assess exposure to terahertz radiation. First experiment of this gyrotron was carried out. After axial alignment, a Gaussian-like beam with a frequency of 599.1 GHz was emitted, achieving continuous oscillation for 10 min with a power output of 2.4 W.

600 ghz连续波回旋管作为电磁场暴露评估光源的首次实验

随着太赫兹器件的快速发展，人类对太赫兹波的暴露增加，在商业化之前需要进行彻底的安全评估。尽管600 GHz这样的频率在下一代技术中具有重要意义，但目前还没有专门设计用于如此高频率的暴露实验的回旋管。因此，我们开发了一个具有高斯光束输出的600 ghz连续波（CW）回旋管来评估太赫兹辐射的暴露。对该回旋管进行了首次实验。轴向对准后，发射频率为599.1 GHz的类高斯波束，连续振荡10 min，输出功率为2.4 W。
