Performance of the thermal neutron detector array in Yangbajing, Tibet for cosmic ray EAS detection.

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. Given the success of the PRISMA-YBJ array, a new type of thermal neutron detector array was installed at the high-altitude cosmic ray observatory in Yangbajing, Tibet. The array consists of 16 EN-detectors and utilizes a new type scintillator based on a compound alloy of ZnS(Ag) and B2O3 with natural boron. This report describes the deployment of the detector array and its operational results. [ABSTRACT FROM AUTHOR]
