[en] In order to study the cosmic rays at different altitude and latitude in Korea, Basic Atomic Energy Research Institute (BAERI) has been constructing the detection facility of charged and neutral particles at the atmosphere. The measured cosmic rays should be precisely interpreted for the cosmic ray distinction from the environmental radiations. The whole system consists of the neutron monitors, the charged particle detectors and signal process system. The prototype detector for the charged particle was fabricated and its detection efficiency, noise level, energy spectrum has been measured by using the cosmic rays. The descriptions of the scintillator, PMT, WLS, fabrication method and experimental setup are presented the following

[en] The Rare Isotope Accelerator complex for ON-line experiments (RAON) is a new radioactive ion beam accelerator facility under construction in Korea. The large acceptance multi-purpose spectrometer (LAMPS) is one of the experimental devices for nuclear physics at RAON. It focuses on the nuclear symmetry energy at supra-saturation densities. The LAMPS Collaboration has developed and constructed various detector elements, including a time projection chamber (TPC) and a forward neutron detector array. From the positron beam test, the drift velocity of the secondary electrons in the TPC is $5.3\pm <!--\; ??\; -->0.2$ cm/μs with P10 gas mixture, and the position resolution for pads with dimensions of 4 $\times <!--\; ??\; -->$ 15 mm${}^2$ is in the range of $\sim <!--\; ???\; -->$ 0.6–0.8 mm, depending on the beam position. From the neutron beam test, the energy resolution of the prototype neutron detector module is determined to be 3.4%, and the position resolution is estimated to be better than 5.28 cm. At present, the construction of the LAMPS neutron detector system is in progress.
