Abstract
Neutron scattering experiments are indispensable for the structural analysis of substances. Large-scale experimental facilities are constructed all over the world. However, there are not enough detectors that detect neutrons well because a neutron is difficult to detect directly. A 3He gas detector, which is most often used, is the most ideal detector for neutrons; however, it has a low counting rate and low position resolution. A 2012 model for the 6Li time analyzer (LiTA12) system is developed for overcoming the weaknesses of the 3He detector. The LiTA12 system is a two-dimensional (2-D) detector system that has a high count rate and a comparatively high position resolution. Furthermore, the LiTA12 system attains a high counting rate of 1.2 million counts per second per square centimeter, a position resolution of 3mm, and a detection area of 5cm × 5cm. The detection efficiency of the system is approximately 48% compared to that of a 3He detector. The LiTA12 system is expected to be used in high-counting-rate neutron experiments such as small-angle scattering experiments.
