Yudai Shigekawa, a PhD student from Osaka, spent a year with the Vienna group. Today, almost exactly one year after his arrival, he disassembled the experimental set-up again, ready to be shipped back to his home university.
Yudai constructed an experiment to investigate the decay of U-233 into Th-229. The U-233 sample was sandwiched in between an alpha detector (for measuring alpha particles with high energy and time resolution) and an MCP (to perform spectroscopy on low-energy electrons). The experiment used coincidences between alpha particles and IC electrons to search for the IC decay channel of the Th-229 isomer, and to measure the isomer energy. Over the course of the year, Yudai brought a lot of knowledge into the group, especially with regards to alpha- and electron measurements, and in the preparation of samples. His research stay also included visits to nuClock partners in Munich and nuClock associates at GSI.
Yudai, thanks a lot for staying with us!
