Direct numerical simulation on non-equilibrium superconducting dynamics after neutron capture in MgB2 superconductor

In order to examine a potentiality of an MgB2 narrow strip as a neutron detector, we perform numerical simulations on non-equilibrium superconducting dynamics by solving the time-dependent Ginzburg–Landau equation coupled with the Maxwell and the heat diffusion equations. The simulation reveals a time period of the electrical response associated with the non-equilibrium superconducting dynamics after a neutron is captured on the top surface of the MgB2 strip.
