Abstract
A weakly ionized plasma detector was designed for the terahertz (THz) continuous wave detection. The effect of inert gas pressure, components, and discharge current on the detector´s responsivity and stability was investigated. Experiment results reveal that the detector´s responsivity can be as high as 194.4 V/W and its signal-to-noise ratio can reach 560 at 0.187 THz.
