The Development of Monochromatic Neutron Tomography System at Low Flux Research Reactor

Abstract

Satu sistem tomografi monokromatik neutron telah direka bentuk di reaktor penyelidikan 1MW TRIGA MARK II milik Agensi Nuklear Malaysia (Nuklear Malaysia) yang terletak di Bangi, Selangor. Kamera CCD digunakan dalam proses pengumpulan data dan sistem ini dinilai dengan menggunakan palam pencucuh. Pembinaan semula imej dijalankan berasaskan kaedah filtered back-projection dan lelaran. Keseluruhannya, 25 data projeksi digunakan dalam proses pembinaan semula imej. Kata kunci: Monokromatik, tomografi neutron, kamera CCD, filtered back–projection, lelaran, pembinaan semula imej A new monochromatic neutron tomography system was built utilizing the Malaysia Nuclear Agency 1MW TRIGA MARK II research reactor located at Bangi, Selangor. The CCD camera was used in data capturing and the system was evaluated using an experimental phantom made from spark plug. Reconstruction was based on the filtered back-projection and the iterative approach. Altogether 25 projections were used in the reconstruction and results discussed.
