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.
