项目摘要

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.

我的JSP奖学金的最后几个月致力于准备即将在接下来的秋天进行的Palis委托实验。这包括将PALIS设置安装回Bigrips F2室，并努力解决2015财年之前的实验中出现的问题，例如隔离影响激光束定位的振动源。此外，开发了用于最终瞄准激光的电动阶段。在秋季提供了关键的激光对齐帮助的测量过程中，该阶段被成功地使用。为主要的JSP奖学金研究项目，确定了多个潜在的电离方案，用于在合并的染料和钛合金上利用osmium和Tungsten。为了应用这些方案，已经模拟了PALIS系统内的共振电离过程，以确定影响该因素的因素并探测电离效率。当使用注射锁的钛朝着高分辨率的RIS迈入高分辨率RI时，这些模拟将是无价的：蓝宝石激光器最近在与Nagoya合作的离线条件下委托与Nagoya合作。该职位包括为日本进行研究的资金，从而为JSP奖学金所启动的研究项目提供直接延续。
