Mahshid Zare; Behjat Ghasemi; Omid Reza Kakuee; Ali Biganeh

Volume 3, Issue 3 , June 2022, Pages 1-5

http://dx.doi.org/10.22034/rpe.2022.336848.1072

Abstract
  The potential biomedical application of Positron Annihilation Spectroscopy (PAS) for nonstructural characterization of normal and cancer cells was not thoroughly employed and researched. In this paper, the experimental investigation of the oxygen sensing ability of the PAS technique for tumor imaging ...  Read More

Analysis and design of a 2.45 GHz RF power source for a miniature electron cyclotron resonance ion source

Hamid Rahimpour; HamidReza Mirzaei; Masoomeh Yarmohammadi Satri

Volume 3, Issue 3 , June 2022, Pages 7-15

http://dx.doi.org/10.22034/rpe.2022.334260.1058

Abstract
  A high-power solid-sate based radio frequency power source is introduced in this paper. Solid-state based amplifiers are much more efficient than microwave tubes and can be used in compact electron cyclotron resonance (ECR) ion sources. A reliable negative bias voltage controller is proposed to drive ...  Read More

Hafez Taghipour Aslani; Alireza Jokar; Aliakbar Mehmandoost-Khajeh-Dad; Hossien Rafi-kheiri

Volume 3, Issue 3 , June 2022, Pages 17-21

http://dx.doi.org/10.22034/rpe.2022.336209.1066

Abstract
  To measure excitation functions of particle-induced prompt gamma-ray production reactions on Li, a thin LiF target was fabricated by thermal evaporation technique onto self-supporting Ag film. The thickness and the stochiometric ratio of the thin LiF target was measured using Elastic Backscattering Spectroscopy ...  Read More

Investigation of the coincidence Doppler broadening ratio curve of well-annealed copper

Ali Biganeh; Hosein Rafi-Kheiri; Omidreza Kakuee

Volume 3, Issue 3 , June 2022, Pages 23-27

http://dx.doi.org/10.22034/rpe.2022.336062.1065

Abstract
  A two-dimensional coincidence technique is carried out to suppress the background for exploring the contribution of positron annihilation with core electrons. The spectrometer is composed of two face-to-face HPGe detectors. To test the performance of the system, the Coincidence Doppler Broadening (CDB) ...  Read More
