| Abstract | The electron current measurement module is a key component of the superconducting cryomodule testing platform. Serving as a vital monitoring signal device within the coupler interlock system, this module monitors the electron cloud of high-energy power couplers and waveguide systems to ensure their effective protections. This article details the design and performance testing of the electron current measurement module, highlighting key technologies including anti-interference, weak cur-rent detection, multi-channel signal acquisition and processing, and weak current calibration. This module boasts a large dynamic range, high precision, and multi-channel weak current detection, featuring 32 detection channels with a detection range of nA~10μA. Its detection accuracy surpasses 1nA, and its response time is under 5ms. Additionally, the module's design took into account the impact of ionizing and electromagnetic radiation on its performance to ensure its reliability and stability. |
