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.

Lund, Sweden; Significant amounts of travel will be needed during the construction project

The Science Directorate at the European Spallation Source (ESS) invites applications for an instrument scientist for the LOKI instrument for Small-Angle Neutron Scattering (SANS).

The Neutron Instruments Division houses the instrument scientists and post-docs, responsible for designing, constructing and then operating the neutron instruments of the ESS. New designs for a wide range of neutron instruments are in the process of being implemented, optimized to take full advantage of the unique long-pulse time structure of the ESS neutron source. There are currently 15 instruments under construction for ESS, of which there are two instruments for Small-Angle Neutron Scattering (SANS); LOKI and SKADI.

The current position will provide support for the lead scientist for LOKI, a high-throughput broadband SANS instrument, optimized for soft matter and life sciences. The immediate mission is to act as the scientific co-lead of the project to design, procure, install and commission the LOKI instrument. The two instrument scientists will work closely with the lead engineer, forming the core instrument team. It is expected that the instrument project will run until 2022, followed by commissioning and operations, at which stage the mission will be to operate the instrument within the ESS user programme.
LOKI is being built as an in-kind contribution from the UK, with the ISIS facility in Oxfordshire identified as the lead partner. The successful candidate will be primarily based ESS in Lund, but frequent travel between ISIS and ESS will be required throughout the instrument construction project.

The position will also require work in support of delivering scientific results for both SANS instruments. This may involve specifying sample environment equipment, software needs and support and coordination with SKADI, the other SANS instrument under construction at ESS.

The successful candidate must be active in a scientific field of direct relevance to LOKI (soft matter, life science, or materials research). The selected candidate will be given the opportunity to develop their own research projects, preferably at operating neutron research centres. Synergies with the neighbouring MAX-IV synchrotron as well as strong links with universities will be encouraged. ESS will support and encourage the candidate to take up an adjunct position at a university in an ESS partner country, in order to facilitate their own research.

What ESS can offer

ESS can offer you a variety of things, such as passionate colleagues, a vibrant melting pot of diversity, and a challenging and high paced work environment where our employees take great pride in designing and building a world leading facility for materials research.

If you were to join ESS, you would become an important piece of the puzzle, since all our skilled staff are needed in order to fulfill the overall mission. We value and need expertise, innovative minds, great ways of leading and interacting with others, and the ability to work with people regardless of culture and background.

Duration & Location

The position is permanent with six months initial probationary period. Your work place will be situated in Lund, Sweden. Significant amounts of travel will be needed during the construction project. The position is to be filled as soon as possible.

Essential qualifications and experience

• PhD in experimental studies in the natural sciences relevant to the LOKI scientific programme
