共鳴イオン化分光法による不安定タングステン、オスミウム同位体の研究

在JSPS的最后几个月里，我致力于为即将到来的PALIS调试实验做准备，该实验将于次年秋天进行。这包括将PALIS装置安装回BigRIPS F2腔室，并解决2015财年之前实验中出现的问题，例如隔离影响激光束定位的振动源。此外，还研制了一种用于激光最终瞄准的机动平台。该平台在秋季的测量中成功使用，提供了关键的激光对准辅助。关于JSPS奖学金的主要研究项目，利用染料和钛：蓝宝石组合体系确定了锇和钨的多种潜在电离方案。为了应用这些方案，利用速率方程模拟了palis系统内的共振电离过程，以确定影响共振电离的因素，并探讨了电离效率。在利用注入锁定钛蓝宝石激光器进行高分辨率RIS的过程中，这些模拟将是非常宝贵的，该激光器最近在与名古屋大学合作的锆离线条件下投入使用。在完成JSPS奖学金后不久，我开始了芬兰学院资助的为期三年的芬兰职位。这一职位包括为日本的研究提供资金，从而能够直接继续在JSPS研究金下开始的研究项目。

The last months of my JSPS fellowship were dedicated to preparing for upcoming PALIS commissioning experiments taking place in the following autumn. This included installing the PALIS set-up back to the BigRIPS F2 chamber and work to resolve issues that arose during the previous experiments in FY2015, for example isolating sources of vibrations that affected the laser beam positioning. Additionally, a motorized stage for final aiming of the laser was developed. The stage was successfully utilized during the measurements in autumn where provided critical laser alignment aid.Regarding the primary JSPS fellowship research project, multiple potential ionization schemes were identified for osmium and tungsten leveraging on the combined Dye and Titanium:sapphire system. In anticipation for applying these schemes, the resonance ionization process within the PALIS-system has been simulated utilizing rate-equations in order to determine the factors affecting the, and to probe the ionization efficiency. These simulations will be invaluable when proceeding towards high-resolution RIS utilizing an injection-locked Titanium:sapphire laser, recently commissioned in an off-line conditions with zirconium in collaboration with the University of Nagoya.Shortly after finishing the JSPS fellowship, I began an Academy of Finland funded 3 years position in Finland. This position includes funding for research Japan thus enabling a direct continuation for the research projects started under the JSPS fellowship.
