The measurement of thermal neutrons generated by cosmic ray extensive air showers (EAS) on the Earth’s surface provides a new method for studying the composition and energy of cosmic rays with energy in the so-called “knee” region. The electron-neutron detector (EN-detector) utilizes a new type scintillator based on a compound alloy of ZnS(Ag) and B2O3 with natural boron. Totally 64 EN-detectors were produced at the laboratory in Hebei Normal University (HNU), Shijiazhuang, Heibei, China. At present 2 clusters (32 detectors) are kept at the laboratory. The performance test of the EN-detector mainly includes the relative gain calibration, the neutron detection efficiency, and comparison of detection efficiencies between different types of the reflection layer. The triggered EAS events of the two clusters are recorded and analyzed offline in order to compare with ones at high altitude.
