Observation of meander pattern in signals from superconducting MgB2 detector by scanning pulsed laser imaging

► We fabricate a superconducting MgB2 meander detector as a solid-state neutron detector. ► MgB2 detector uses XYZ stage, optical fiber and focused lens to scan as a microscope. ► The 6 μm line-and-space in meandering pattern can be resolved in signals against pulsed laser.
