## Description

- description: We have proposed a quench detection method that uses a low-temperature
    superconducting quench detector (LTS QD) for rare-earth barium copper oxide (REBCO)
    coils at 4.2 K. Previous studies demonstrated the quench detection with a LTS
    QD in a layer-wound REBCO coil. In this study, the quench detection performance
    of LTS QDs for insulated, no-insulation (NI), and metal-as-insulation (MI) REBCO
    pancake coils was experimentally compared. An experiment that used a Nb–Ti/Cu–Ni
    QD installed in insulated, NI, and MI REBCO coils demonstrated a quench detection
    before a thermal runaway in the coil at 4.2 K and 0–9 T. Nb–Ti/Cu–Ni QD showed
    slower quench detection in the coils without turn-to-turn insulation. It would
    be due to the small heat density around the hot spot and large heat exchange between
    the Nb–Ti/Cu–Ni QD and REBCO coils. In conclusion, this study indicated that the
    turn-to-turn resistance in the REBCO coil and thermal gap conductance between
    the coil and LTS QD are key parameters for the design of LTS QDs. Moreover, feasibility
    of the quench detection with appropriate LTS QDs for the insulated, NI, and MI
    REBCO pancake coils was demonstrated at 4.2 K.
