Abstract
In 2009, the King Abdulaziz City for Science and Technology (KACST) launched a project involving the establishment of the first radiation detector laboratory in Saudi Arabia. This project aims to design, develop, and operate several multi-purpose radiation detectorsdetectors, as well as to establish collaboration with international institutions to facilitate the transfer of technological knowledge to Saudi scientists. Since the project was launched, several radiation detectors that employ different techniques have been developed by the KACST-based researchers or through their collaboration with international institutes. Data obtained by these detectors are of great importance in several applications, such as in cosmic raycosmic-ray modulation and in solar-terrestrialsolar-terrestrial interaction research. This paper describes the detectors developed thus far and presents some of the obtained results.
