Abstract

The generation of high-intensity radiation fields in the accelerators, shield design is made to attenuation permissible levels of radiation dose. For determination of shield material, thicknesses, weight, installation and maintenance costs as well as radiation attenuation properties are taken into consideration such factors. Effective radiation for shielding is neutrons in proton accelerators and shield design is made for neutrons. Concrete, soil and iron are widely used as a shield material

Abstract

Özet: Yüksek yoğunluklu radyasyon alanlarının oluştuğu hızlandırıcılarda, radyasyon seviyesini izin verilen doz değerlerine zayıflatmak için zırh tasarımı yapılır. Zırhın belirlenmesinde, radyasyon zayıflatma özellikleriyle birlikte kalınlığı, ağırlığı, kurulum ve bakım maliyeti gibi faktörler de göz önünde bulundurulur. Proton hızlandırıcılarında, zırhlama için etkin olan radyasyon nötronlardır ve zırh tasarımı nötronlara göre yapılır. Zırh maddesi olarak genellikle beton, toprak ve çelik kullanılır. Bu çalışmada, hızlandırıcı zırh tasarımında gerekli minimum yan duvar zırh kalınlıklarını belirlemek için farklı yoğunluklarda (toprak, standart beton, demir) zırh maddeleri seçildi. Zırh kalınlıkları, FLUKA Monte Carlo kodu ile belirlendi. Anahtar kelimeler: Proton hızlandırıcı, zırh tasarımı, FLUKA, demir Investigation of Neutron Attenuation Properties for the Different Density Materials Abstract: The generation of high-intensity radiation fields in the accelerators, shield design is made to attenuation permissible levels of radiation dose. For determination of shield material, thicknesses, weight, installation and maintenance costs as well as radiation attenuation properties are taken into consideration such factors. Effective radiation for shielding is neutrons in proton accelerators and shield design is made for neutrons. Concrete, soil and iron are widely used as a shield material. In this paper, the different density of the shielding materials (soil, standard concrete, iron) were selected to determine for the minimum thickness of the side wall for shielding design of proton accelerator. The thickness of the shielding is obtained by a simulation with the Monte Carlo Code FLUKA. Key words: Proton accelerator, shield design, FLUKA, iron.
