Abstract
The paper aims to discuss the response of the Micro-Mesh Gaseous Structure (Micromegas) detector to high energy x-ray with 2.3 MeV energy using photon to neutron converters by Monte Carlo N-Particle (MCNPX) code in addition to optimization of the detector components. According to the results, D2O with 2×10-5 efficiency is the best target to convert photon with 2.3 MeV energy to neutron. To study the response of the Micromegas detector to high energy x-ray, the thickness of upper electrode, and the type of gas in the detector studied and optimized. The response of the detector has been optimized based on the gas type, and the thickness of upper electrode. The results show that this detector has the ability to detect high energy x-rays with energy above 2 MeV. The Monte Carlo results were shown the output current of the micromegas detector is 5.12 pA per one input hard X-ray photon.
