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

我在JSPS奖学金的最后几个月致力于为即将到来的Palis调试实验做准备，该实验将于明年秋天进行。这包括将Palis设置安装回BigRIPS F2小室，并努力解决2015财年之前的实验中出现的问题，例如隔离影响激光光束定位的振动源。此外，还研制了用于激光最终瞄准的电动工作台。在秋季的测量中，该平台被成功利用，提供了关键的激光对准辅助。关于JSPS的主要奖学金研究项目，确定了在染料和钛：蓝宝石组合系统上利用Os和W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体系中的共振电离过程，以确定影响电离效率的因素，并探讨了电离效率。这些模拟对于利用注入锁定的钛：蓝宝石激光器进行高分辨率RIS时将是无价的，最近与名古屋大学合作在离线条件下委托使用钛：蓝宝石激光器。在完成JSPS奖学金后不久，我开始在芬兰接受芬兰学院资助的3年职位。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日本科学和应用学会研究金下启动的研究项目。

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.
