Research Abstract

We have developed an arrayed MgB2 sensor to detect thermal neutrons. Multiple sensors are well fabricated to exhibit almost the same superconducting characteristics. We carried out the neutron irradiation experiment at J-PARC. However, the second machine time was cancelled due to huge earth quake in Japan. Instead, we succeeded in doing the laser irradiation experiment using a pulsed laser with a computer-controlled XYZ stage, and demonstrated the good characteristics using a 2x2 CH MgB2 sensor.
