Shahryar Malekie; Seyed Musa Safdari; Sedigheh Kashian; Morteza Akbari

Volume 4, Issue 4 , October 2023, Pages 1-6

  Polycarbonate-bismuth oxide composite has been used as a beta-ray sensor in the previous works. Calculation of two main quantities namely stopping power and range of electrons in this material can be useful to evaluate the optimal thickness of the sensor. Thus, in this study, the range of electrons and ...  Read More

S. Taher Aminfarkhani; Ahmad Lashkari; S. Farhad Masoudi

Volume 4, Issue 4 , October 2023, Pages 27-34

  The present work is concerned on neutron flux increasing in Tehran Research Reactor (TRR). TRR is a 5 MW pool-type research reactor with plate type fuels in which the light water is used as both the coolant and moderator. The main goal of this paper is reaching to the average thermal neutron flux of ...  Read More

Enhancing inertial confinement fusion with doped beryllium ablator layer in indirect drive scheme

Babak Khanbabaei

Volume 4, Issue 4 , October 2023, Pages 35-42

  Indirect drive inertial confinement fusion (ICF) holds promise for achieving practical energy generation through controlled fusion reactions. However, the efficiency of ICF is constrained by the Be ablator material used to contain the fuel. To overcome this limitation, researchers have proposed doping ...  Read More

Two-dimensional simulation of argon dielectric barrier discharge (DBD) plasma actuator with COMSOL Multiphysics

Ramin Mehrabifard

Volume 4, Issue 4 , October 2023, Pages 43-50

  Dielectric barrier discharge (DBD) plasma is used for various applications. DBD is also one of the most efficient and low-cost methods for active fluid flow control. In this study, a detailed physical model of DBD in atmospheric pressure at 1 kV DC voltage is developed with COMSOL Multiphysics software. ...  Read More

Experimental study on the performance of a THGEM detector for X-rays

Elham Edalatkhah; Shahab Sheibani

Volume 4, Issue 4 , October 2023, Pages 51-55

  By expanding the applications of GEM detectors, a newer pattern of such detectors was introduced in 2004, named THGEM detectors. In this work, a sample of an X-ray detector was designed and constructed using 2cm×2cm THGEMs domestically produced with a thickness of 250 μm, a hole diameter of ...  Read More
