Abstract
In this paper, we present the results of experiments and computer simulations to make clear the quench propagation properties in Bi-2223/Ag superconducting multifilament tape. We developed a computer code based on the two-dimensional finite element method (2-D FEM). Computed voltage and temperature traces during a quench agree well with the experimentally recorded voltage and temperature traces. Good agreement validates the computer code, making a useful tool in developing protection strategies for high-temperature superconducting (HTS) coils. Therefore, we simulate the quench process in a single pancake coil wound with Bi-2223/Ag superconducting multifilament tape with background magnetic filed up to 10 T at 20 K using the developed computer code. The quench propagation properties and stability in HTS coils are discussed and compare with those in low-temperature superconducting (LTS) coils.
