Outline of Final Research Achievements

Observations of the Geminga and the Dragonfly pulsar resulted in no significant detection of signals. That indicates that these pulsars do not have a hard spectrum like the Crab pulsar above 10 GeV. During the analysis of those data, a new technique of the data analysis was developed, which can be considered as an important achievement. As for the development of the central pixel of the large-sized telescope of CTA, we decided to use the fast reading of the PMT current to detect the optical pulsation. Adjustment of the reflector will be achieved by the CCD cameras installed on the individual mirror facet.
