The Cherenkov Telescope Array (CTA) project is an ambitious international effort involving 212 institutions from 32 countries. The primary goal of the project is to explore sources of high-energy radiation in the universe, such as black holes and supernovae. The collaboration has led to the establishment of the Cherenkov Radio Telescope Group, which is responsible for constructing and operating two telescope arrays in different locations.

The first site is on La Palma Island, Kingdom of Spain, where 19 telescopes are being constructed. The second site is located near the Paranal Observatory in the Republic of Chile, with 99 telescopes planned. This strategic placement allows for comprehensive observation coverage of both the northern and southern hemispheres.

Construction has already begun on the Cherenkov Radio Telescope Group on La Palma Island, and the project is expected to be completed around 2025.

In 2015, the National Astronomical Research Institute of Thailand (NARIT) signed a memorandum of understanding with the DESY Institute, marking the beginning of their collaboration in particle astrophysics, specifically in astroparticle physics related to the Cherenkov Ray Telescope Group project.

NARIT is currently involved in designing and developing a "Telescope Mirror Coating Machine" for the CTA project. This collaboration includes the Synchrotron Light Research Institute, Suranaree University of Technology, and Chulalongkorn University. Drawing on their experience in constructing the National Telescope mirror coating machine, NARIT aims to coat more than 6,000 mirrors for the Cherenkov Ray Telescope Project. Each mirror has a diameter of 1.2 meters, and due to the outdoor location of all telescopes in the project, the mirrors need to be recoated every 6 years to counteract corrosion and maintain their reflective properties.
