Abstract

For the generation of beams with the offline ion source at the Facility for Rare Isotope Beams (FRIB), suitable source samples are required. Arsenic-73 is a frequently requested user beam due to its significance in nuclear structure studies and astrophysics. In this work, we outline the process of preparing a ⁷³As source sample, containing (5.76 ± 0.37)∗10¹⁴ atoms of ⁷³As, which was successfully used to generate a ⁷³As beam for a multi-day user experiment. Silver arsenate was chosen as the chemical form, due to its favorable volatility within the designated operating temperature range. We refined the precipitation method using stable arsenic prior to its application with the ⁷³As sample, resulting in precipitation yields of (99.4 ± 4.5)%.

制备用于脱机离子源的73As源样品。

在稀有同位素束流装置（FRIB）中，脱机离子源产生束流需要合适的源样品。由于砷-73在核结构研究和天体物理学中的重要意义，它是一种常用的用户光束。在这项工作中，我们概述了制备含有（5.76±0.37）∗1014个73As原子的73As源样品的过程，该样品成功地用于产生用于多日用户实验的73As光束。选择砷酸银作为化学形式，因为它在指定的工作温度范围内具有良好的挥发性。在将稳定砷应用于73As样品之前，我们对沉淀方法进行了改进，使沉淀率达到（99.4±4.5）%。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
