Design and simulation of an S-Band tunable solid-state power amplifier as an RF injector into a miniature ECR ion source

Hamid Rahimpour; HamidReza Mirzaei; Masoomeh Yarmohammadi Satri; Zafar Riazi Mobaraki

Volume 3, Issue 4 , October 2022, Pages 1-5

  A continuous-wave solid-state-based power amplifier is designed and simulated in this paper to work as an RF injector into an ECR ion source chamber. Employing a solid-state radio frequency power amplifier, instead of microwave tubes, leads to having higher efficiency, lower price, compact size, and ...  Read More

Determination of TG-43 dosimetric parameters for I-125, Ir-192 and Co-60 brachytherapy sources using the Monte Carlo simulation

Milad Payandeh; Mahdi Sadeghi; Dylan Richeson; Somayeh Gholami

Volume 3, Issue 4 , October 2022, Pages 7-15

  It is important to have accurate information regarding the dose distribution for treatment planning and to accurately deposit that dose in the tissue surrounding the brachytherapy source. However, the practical measurement of dose distribution for various reasons is associated with several problems. ...  Read More

Design of a two-dimensional pseudo coincidence Compton suppressor system for neutron activation analysis

Ali Biganeh; Banin Shakeri Jooybari

Volume 3, Issue 4 , October 2022, Pages 17-21

  Compton scattering events are the main source of error on the peak counting during the Neutron Activation Analysis (NAA). The Compton suppressor system in instrumental NAA reduces the detection limit of the technique and leads to a data with a higher degree of precision. In this paper, a two-dimensional ...  Read More

  The pressurizer is a key equipment to ensure the safe operation of pressurized water reactor by maintaining the reactor coolant system pressure within allowed tolerances. Various pressure control systems (Pressurizer) are adopted in industrial applications to satisfy their characteristics. In accordance ...  Read More

Kinetic investigation of tellurium hexafluoride production using the volumetric method

Amir Charkhi; Parisa Zaheri; Amjad Sazgar; Iman Dehghan

Volume 3, Issue 4 , October 2022, Pages 31-34

  Since the production of tellurium hexafluoride gas requires the design of a suitable reactor system, so the study of tellurium oxide fluorination kinetics is of great importance. For this purpose, a novel laboratory system was designed and constructed to study the fluorination reactions by the volumetric ...  Read More

Comparison of conversion factor methods in spectrometric dosimetry systems based on NaI(Tl) scintillation detectors

Akbar Abdi Saray; Hossein Zaki Dizaji; Mortaza Taheri Balanoji

Volume 3, Issue 4 , October 2022, Pages 35-41

  To monitor personal safety in the fields of biomedical and health physics, it is necessary to be aware of radiation doses to protect the health and safety of persons. Radiation protection quantities such as air kerma, ambient dose equivalent, and exposure dose rate are obtained by the measured spectrum ...  Read More
