| Sumari: | Title screen The Bonner sphere spectrometer is widely used to measure the neutron spectrum; however, it is bulky and heavy. Variants of Bonner sphere spectrometer aiming to reduce weight and volume have been reported where moderating spheres have been changed by multi or nested cylinders and cubes. In these variants passive and active thermal neutron detectors have been included to habilitate the spectrometer to different experimental situations. In this work Monte Carlo methods were used to design a novel passive neutron spectrometer with six 20.5 x 20.5 cm2 surface area regular parallelepipeds made of polyethylene moderators with 0.5, 4.5, 8.5, 12.5, 16.5 and 20.5 cm-thickness. Thermal neutrons are detected using the technique of pairs of thermoluminescent dosimeters (TLD600 and TLD700). For each moderator the response function was estimated; in each TLD, the response is the amount of 6Li(n, α) nuclear reactions occurring in the TLD600 and TLD700 for 1E(-9) to 20 MeV neutrons. In addition, the absorbed dose, due to neutrons and γ-rays, in the TLDs were estimated. The total responses for the TLD600 and TLD700 inserted in the Regular Parallelepiped Spectrometer were calculated and compared with the total response of Bonner sphere spectrometer with TLD600. The fabrication of this novel spectrometer is simple, it is portable and compact whose weight and volume is 3.39 times smaller than weight and volume of the passive Bonner sphere spectrometer Текстовый файл AM_Agreement |
