In the present work, the correlated sampling technique in Monte Carlo calculations related to diamond dosimetry and graphite calorimetry will be described. The egs_chamber and DOSRZnrc user-codes included in the EGSnrc package are used. Egs_chamber is already provided with routines enabling the use of correlated sampling while an in-house implementation of this technique was made in the origina...
The verification and validation (V&V) of the Serpent 2 Monte Carlo code for 3-D reactor dosimetry applications is being carried out at VTT. Two code-to-code computational benchmark cases were calculated by MCNP 2. efficiency different variance reduction techniques was appraised. part currently includes two experimental benchmarks from SINBAD database: Pool Critical Assembly-Pressure Vessel ...
background: the presence of a wedge filter in the beam trajectory can modify the beam quality and cause some changes in the dosimetry parameters which are usually difficult to be measured directly and accurately. material and methods: in this study the mcnp-4c monte carlo code was used to simulate the 9 mv photon beam generated by a linear accelerator. upon getting a good agreement between the ...
A dosimetry system based on Al2O3:C radioluminescence (RL), and RADPOS, a novel 4D dosimetry system using microMOSFETs, were used to measure total scatter factors, (S(c,p))(f(clin))(det), for the CyberKnife robotic radiosugery system. New Monte Carlo calculated correction factors are presented and applied for the RL detector response for the 5, 7.5 and 10 mm collimators in order to correct for ...
یکی از مهم ترین عوامل خرابی سدها، پدیده روگذری می باشد که خود ناشی از علل متعددی است. از جمله اثر گذارترین عوامل بر پدیده روگذری، سیلاب و خیزاب ناشی از وزش باد می باشد که در این پروژه اثر این دو عامل مورد بحث و بررسی قرار گفته است. در مطالعه انجام شده، احتمال وقوع روگذری ناشی از باد و سیلاب در دریاچه سد خاکی دوراهان در استان چهار محال و بختیاری بررسی شده و در نهایت احتمال وقوع این پدیده به روش...
