Job openings

CH-5232 Villigen PSI, Switzerland

Fundamental physics experiments with ultracold neutrons (UCN) are limited by neutron counting statistics. New developments to increase UCN intensities would push the limits of our knowledge further, e.g. on the not-yet understood asymmetry observed between matter and antimatter in our Universe, on the production of light elements after the Big Bang, and on important parameters of the Standard Model of particle physics.
The strategy for the next generation n2EDM experiment based at PSI in Switzerland is to increase UCN statistics by a larger precession chamber volume, and by enhancing the PSI UCN source output several factors due to an improved control of the material structure of the solid deuterium (sD2) converter.

The Laboratory of Particle Physics (LTP) at the Paul Scherrer Institute pursues fundamental research, addressing the most up to date questions in modern physics. Together with researchers from Switzerland and abroad, we use the world’s most intensive sources for low-energy muons, pions and ultracold neutrons at PSI.

The main strategy in this PhD work is exploiting material structure information from the UCN energy spectra extracted from the sD2 converter, including the time evolution of the sD2 at around 5 K, and implementing this into neutron scattering kernels for the simulation of the UCN output matching all experimental observations. The expected result of this project is improving the modeling capabilities of converter materials to enhance the PSI UCN source output especially for the n2EDM project, and the output of UCN sources in general for fundamental physics experiments. A novel neutronics simulation model linking consistently all neutron observations from the sD2 converter operation and dedicated test experiments would help in our optimization strategy to increase the UCN output.
We offer a 48 months position for a PhD student with starting date 1 September 2018. The academic supervisor will be Prof. Klaus Kirch from ETHZ/PSI. The PhD student will work in a very active expert environment in experimental neutron physics involving the UCN physics group and the neutronics simulation group at PSI.

University degree in physics with strong background in mathematical, numerical and experimental methods, advanced programming skills, a creative personality focused on problem-solving, excellent communication skills in English.

Oak Ridge, Tennessee, USA

The Neutron Scattering Division within the Neutron Sciences Directorate is seeking to fill a postdoctoral position to development an in situ sample environment for neutron reflectometry (NR) and use it to perform studies of corrosion mechanisms at the interface of a high temperature alloy and a molten salt. The extreme corrosive nature of molten salt heat transfer fluid constitutes the dominant technological barrier that must be mitigated for widespread implementation of third generation concentration solar power systems. Ion transport across the salt/alloy interface is the defining physical process which enables corrosion in molten chlorides, yet there is no definitive understanding of the interfacial corrosion mechanism, the interplay with alloy structure, and the commensurate performance of proposed protecting layers. Direct investigations of the structure of the molten salt/alloy interface using NR will provide the critical information needed to mitigate alloy corrosion in molten chloride salts.

Major Duties and Responsibilities

• Design in situ cell for performing NR measurements.
• Independently plan, design and execute in situ NR experiments.
• Collaborate with other scientists and technical personnel to carry out research projects.
