    Superconducting tunnel junction photon detectors, which exhibit high performance in a range between infrared and soft x-rays, are sensitive to magnetic flux quanta, so called vortices, trapped in the superconducting thin films. The vortex trapping easily occurs when a residual magnetic field is...
