Abstract

A novel quench detection method using microelectro- mechanical system (MEMS) sensor technology has been investigated in use for high temperature superconducting (HTS) conductors such REBCO tape cables. The sensor array along a superconducting cable, such as a cable-in-conduit-conductor (CICC), is installed in a cooling channel. It will allow sensitive and quick detection for a local quench of a superconducting cable. This work has confirmed that a quench of a single REBCO tape can be detected in liquid nitrogen by a MEMS piezoelectric microphone sensor. The quench detection design utilizing a MEMS sensor array method is discussed for the case of a toroidal field (TF) magnets of a fusion Tokamak device.

An Acoustic Quench Detection Method for CICC Conductor Operating in Gas or Liquid

Dataset Takayasu, Makoto

A method using micro-electro-mechanical system (MEMS) acoustic sensor technology to detect a quench and abnormal behavior of a superconductor is discussed. MEMS of microphone chips are installed along the coolant space of a superconducting conductor to monitor the coolant condition. By arranging the acoustic sensor array in a coolant flow channel, it is possible to quickly detect a change in the local condition of the coolant with precise spatial resolution. This method is useful for monitoring superconducting magnets and power cables, especially those made with a cable-in-conduit-conductor (CICC) configuration.

Coolant Pressure Evaluations for a MEMS Sensor-Array Quench Detection in REBCO CICC Superconducting Cables

Journal Article Takayasu, Makoto - IEEE Transactions on Applied Superconductivity

Here, the initial quench pressure developments for a CICC cable of REBCO tapes have been investigated by numerical analyzing the first law of thermodynamics. The temperature and pressure rise due to the quench has been evaluated for a REBCO CICC conductor operated in helium gas coolant at 26 K. Additionally, a MEMS sensor-in-tube array method has been proposed and discussed for quench detection.
