Spectroscopy of SiPM array detectors by digital spectroscopy method and implementing trapezoidal digital filter

Homa Berjisi; Ali Pazirandeh

Volume 4, Issue 3 , June 2023, Pages 1-8

  Digital spectroscopy with Silicon Photomultiplier (SiPM) array coupled on CsI(Tl) crystal, needs some consideration to achieve desirable energy resolution. an array of SiPMs must be used with large scintillation crystal, therewithal signal from whole SiPMs is not ideal. Also silicon pixels are arranged ...  Read More

Maryam Azizi; Ali Biganeh; Omidreza Kakuee; Behjat Ghasemi; Yashar Vosoughi

Volume 4, Issue 3 , June 2023, Pages 9-14

  Primary standardization of radioactivity is related to the direct measurement of activity in radioactive decay. A large variety of primary standardization techniques have been developed in the past years. The photon-photon coincidence counting is one of the methods for activity determination. This method ...  Read More

Experimental and Monte Carlo investigation of neutron detection by THGEM detector in SQS mode

Mohammad Hadi Najarzadeh; Mohammad Reza Rezaie; Ali Negarestani; Ahmad Akhound

Volume 4, Issue 3 , June 2023, Pages 15-22

  Neutron detection techniques are widely studied in many articles. Most of this research requires a lot of electronic equipment. In this study, using the Thick Gas electron multiplier (THGEM) detector, a new method for neutron detection is proposed to reduce electronic equipment. In the neutron detection ...  Read More

Measurement of tritium concentration in heavy water by azeotropic distillation

Reza Pourimani; Mohammad Reza Zare; Mehrdad Aghamohammadi

Volume 4, Issue 3 , June 2023, Pages 23-27

  In this work, the concentration of tritium in D2O of various degrees of purity was measured. Samples were taken from the Arak heavy water plant and tritium concentrations were determined using a liquid scintillation detector (LSC) based on tritium decay. In this work, instead of simple distillation, ...  Read More

‎Simulation of neutron and gamma shielding for an inertial electrostatic confinement fusion device‎

Hadi Zanganeh; Mahdi Nasri Nasrabadi

Volume 4, Issue 3 , June 2023, Pages 29-41

  In this work, neutron and gamma shielding were simulated using MCNPX code for an inertial electrostatic confinement Fusion (IECF) device. In this regard, various properties of shields were investigated. Portland reinforced concrete was considered as the first layer. In addition to being effective in ...  Read More

Measurement and simulation of the effective annual dose and radiation hazards of Jooshan hot spring in Kerman province

Mahmoud Abdoulahpour; Mohammad Reza Rezaie; Saeed Mohammadi

Volume 4, Issue 3 , June 2023, Pages 43-51

  Hot springs are known as one of the hydrotherapy centers in the world and have been welcomed due to their healing properties. Due to the presence of radon and radioactive elements in hot spring sediments, water and soil, these components are radioactive. So far, radiation hazards and the annual effective ...  Read More

In this article, to innovate in achieving a better power and energy gain of neutron-free p11B fusion reaction, the improvement of the cross-section and also the kinetic effects. ...  Read More

Secondary particle dose assessment during the proton therapy of liver cancer: A Monte Carlo study

Leyli Mogheiseh; Ali Asghar Mowlavi; Sayyed Bijan Jia; Reza Shamsabadi

Volume 4, Issue 3 , June 2023, Pages 65-72

  Proton therapy of liver tumors can be challenging due to the absorbed dose of produced secondary particles in non-target organs. This study aims to evaluate the absorbed dose of secondary particles during the proton therapy of liver cancer through the MCNPX Monte Carlo (MC) code by a simplified MIRD-UF ...  Read More
