| Outline of Final Research Achievements |
We have developed a micro pattern gaseous detector (MPGD) for neutron imaging. A crystallized photosensitive etching glass (PEG3C) and a funnel type glass capillary plate (CP) were developed as the new material of MPGD. We have also successfully developed an optical imaging gas detector, which consists of a holee-type MPGD, a mirror, and a CMOS camera system, for neutron imaging. The gas detector was filled with Ne (90%) + CF4 (10%) gas mixture at 1 atm. Its performance was investigated using an X-ray beam and a thermal neutron beam at KUANS. Owing to the high imaging capability of the optical imaging gas detector, tracks of alpha rays or 7Li produced by the interaction between neutrons and 10B were clearly observed. The characteristics of detection efficiency and spatial resolution were assessed on the basis of the results of Monte Carlo simulations using a particle and heavy ion transport code system (PHITS).
