Objective: The use of miniature X-ray source in electronic brachytherapy is on the rise so there is an urgent need to acquire more knowledge on X-ray spectrum production and distribution by a dose. The aim of this research was to investigate the influence of target thickness and geometry at the source of miniature X-ray tube on tube output.Method: Five sources were simulated based on problems e...
در چند سال اخیر نیاز به استفاده از منابع انرژی تجدیدپذیر نظیر انرژی خورشیدی، پیل های سوختی و انرژی بادی افزایش یافته است. از این میان پیل های سوختی به دلیل عدم آلودگی، بازدهی بالا و مستقل بودن از شرایط آب و هوایی، منابع انرژی بسیار مفیدی هستند. روش مرسوم برای کنترل این پیل ها استفاده از یک مبدلdc/dc می باشد.در کاربردهای سه فاز مانند درایو موتورهای ac، یک اینورتر هم باید در مسیر مبدل dc/dc قرار ...
in this work, we had examined 7 different types of neutron sources -an isotropic point source, sending 14.1(mev) monoenergetic neutrons ,an spherical source with 30 micron radius sending 14.1 (mev) monoenergetic neutrons, and a 30 micron radius spherical source having gaussian fusion energy spectrum from a d-t fusion, with different bandwidths -1,10,50,100 and 1000 kev and investigated 5 differ...

A new noncentrosymmetric (NCS) sulfide, Ba5In4Te4S7, was synthesized by a conventional solid-state reaction in evacuated closed silica tubes. The compound crystallizes in the orthorhombic space group Imm2 (44), with unit cell parameters a = 39.110(3) Å, b = 4.3763(3) Å, c = 7.3452(6) Å, Z = 2, and V = 1257.18(17) Å(3). The 3D framework of Ba5In4Te4S7 is composed of infinite 1(∞)[InS2Te2](5-) an...
