The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of matter and materials, energy and environment and human health. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2100 people.

For our research on the behaviour of radionuclides in liquid metals in the Laboratory of Radiochemistry we are looking for a
PhD Student
Radionuclide release from liquid metals
Your tasks
In the frame of an international project, we study the evaporation of radionuclides in liquid metal coolants to be used in advanced nuclear reactor systems. Within this scope, your tasks will be:
  • Preparation of lead-bismuth eutectic samples containing radioactive and inactive dopants of different elements
  • Optimizing preparation methods to produce homogeneous materials
  • Studying the evaporation of the dopants from the molten metal by transpiration experiments and Knudsen-Cell mass spectrometry
  • Study the feasibility of matrix isolation techniques combined with Raman and UV-VIS spectrometry for the characterisation of TeOxHy molecules
This work involves both the employment of methods already available in our laboratories as well as development of new/improved techniques for sample preparation and characterisation. Your work in this technically and scientifically challenging research field will be accompanied by experienced specialists.
Your profile
You are a highly motivated candidate who enjoys working experimentally in an interdisciplinary environment. A Diploma or Master degree in chemistry, metallurgy, material sciences or a related field is expected. Solid knowledge in chemistry as well as decent experimental and technical skills are necessary for the execution of the experimental program. Good command of the English language is required. Experience in both handling of molten metals as well as radioactive material count as strong asset. Basic knowledge of radiochemistry is valuable too, but not mandatory. You will work both at the Paul Scherrer Institute in Villigen and at the JRC in Karlsruhe, Germany, while being registered as a PhD student at the ETH Zurich.
We offer
Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.

For further information, please contact Dr Jörg Neuhausen, phone +41 56 310 44 63.

Please submit your application online by 31 July 2020 (including addresses of referees) for the position as a PhD Student (index no. 4702-00).
