There is an increasing interest in Radioactive Ion Beams throughout the world. These ions open new domains of research for nuclear physics, nuclear astrophysics and atomic physics. Two methods are used for the production of these beams: fragmentation of a primary, high energy heavy ion beam passing through a thin target or nuclei production in a thick target bombarded either by a heavy ion beam...
Beijing Radioactive Ion-beam Facilities Isotope Separator On-Line (BRISOL), aiming to generate short life radioactive ion beam (RIB) on-line, is being constructed at China Institute of Atomic Energy(CIAE). Up to now, construction of major equipment for BRISOL is completed, including ion source, vacuum system, separator, optical element, and beam diagnostic system, and assembling is underway in ...
Brachytherapy is a therapeutic approach in which radioactive sources are used to irradiate malignant tumors from near distance. In this study, the comparison of dose distribution in iodine-125 source, STM 1251 and Oncoseed 6711 models was performed using the Monte Carlo Geant4 code. The results obtained from the Monte Carlo calculations have been compared with the TG43U1 formulation and also wi...
The aim of this paper is the examining ways for quality control and calibration of Rams-88 calibrator. The device measures the amount of &gamma and &beta rays in radio medicines by means of the amount of radioactivity of radio nuclide. In this paper experiments has been done for explaining correct operation of these devices using standard method including precision, accuracy and linearit...
The CAlifornium Rare Isotope Breeder Upgrade (CARIBU) is a new radioactive beam facility for the Argonne Tandem Linac Accelerator System (ATLAS). The facility utilizes a Cf fission source coupled with an electron cyclotron resonance (ECR) ion source to provide radioactive beam species for the ATLAS experimental program. The californium fission fragment distribution provides nuclei in the mid-ma...
Up to now, eighteen Target Ion Source Systems (TISSs) have been built and used for the production of radioactive ion beams on SPIRAL 1 facility, based on the IsotopeSeparator-On-Line (ISOL) method. The TISSs are composed of thick carbon targets and of fully permanentmagnet Electron Cyclotron Resonance Ion Sources (ECRISs) of the Nanogan III type. After irradiation and a decay period of two year...
1 " Pop quiz: what source of power doesn't come out of the ground, doesn't burn and isn't radioactive? … The answer is wind power, the technology that has become synonymous with going green " (Walsh 2009).
