Design of Quench Detection System for High-Temperature Superconducting Magnets for Plasma
High-temperature superconducting (HTS) tokamak is significantly smaller in size than low-temperature superconducting (LTS) tokamak. A HTS toroidal field (TF) coil will be manufactured to study the feasibility of HTS tokamak. To ensure the safety of the TF coil, a preliminary design of quench detection system (QDS) has been completed. The QDS consists of a primary detection system and a secondary detection system. The primary detection system based on voltage signal employs co-wound LTS wire and balanced bridge method to mitigate induced voltage noise. To prevent the quench signal from going undetected, a secondary detection system based on radio-frequency reflected wave signal and thermal-hydraulic signals is designed to ensure the safety of the TF magnet system.
