Outline of Final Research Achievements

This project aims to use the next-generation ground-based gamma-ray observatory, the Cherenkov Telescope Array (CTA), as an intensity interferometer and to realize an optical telescope with the highest angular resolution in the world. The PI has been in charge of the development of camera modules to be sued in two telescope designs of the CTA and the development of ray-tracing simulations of the CTA telescopes. We have successfully developed the camera modules with which we imaged short light pulses in the lab. We also made progress in the development of data taking and analysis software. However, there were some drawbacks in the electronics of the camera modules, and one of the electronics parts has not been manufactured yet. Continuos study and development are needed.
