[Neutron] Neutron Beam and Shielding Scientist

Wed Nov 6 16:45:48 CET 2013

Neutron Beam and Shielding Scientist

The Science Directorate at the European Spallation Source (ESS) in Lund, Sweden, invites applications for a Neutron Beam and Shielding Scientist.

Description of directorate/division
The neutron optics and shielding group at ESS is responsible for designing and optimising the neutron optical systems that transport the neutrons from the moderator to the neutron spectrometer sample position. The optics technology involved will involve neutron guides, polarising mirrors, helium 3 analyser cells, collimation devices, diffractive elements such as monochromators, etc.

Description of main responsibilities
The successful candidate will be an expert in optimising neutron beams, their shielding, and the instrument backgrounds, and will work with the rest of the neutron optics group and the instrument teams to ensure that the neutron instrument performance achieves the maximum possible performance with the minimum possible background noise. This will require modeling the ESS beam systems right into the instruments, drawing input from the accelerator and target groups, and including all important physics processes between GeV down to eV energy ranges.

Qualifications
Technical competencies:

  *   A track record of cradle-to-grave neutron instrument modeling, from source to sample, with background evaluation and minimisation
  *   Knowledge of nuclear physics processes from eV to GeV energy ranges, and how they contribute to instrument backgrounds at spallation neuron sources
  *   Multiple years of experience in the use of monte carlo simulations in MCNPX, GEANT4 and similar packages on neutron instrumentation
  *   Deep knowledge of optimisation of these nuclear codes for speed of execution, and the coupling of these packages with the metaheuristic search strategies
  *   Validated results from constructed, running hardware, and a good agreement between the performance of the models and of the as-built system
  *   The ability to write high quality, reliable code in modern object-oriented languages, especially C++
  *   Experience of working in an international environment
  *   Excellent oral and written English skills are a prerequisite; knowledge of other European languages would be an advantage

You as a person:
We truly believe that to enjoy and perform at ESS, you consider these following competences as a significant part of your character:

  *   You enjoy working on difficult, technical problems in teams, but nonetheless you are able to take ownership of a complex problem and use your initiative to find novel solutions
  *   Good communication skills with the ability to resolve discussions when a project is under pressure
  *   Strong analytical approach, with a focus on logic, and the ability to think outside the box, to develop new technology and ideas without simply copying existing concepts

What ESS can offer
At ESS we offer people with talent and passion a unique opportunity to be involved in the development and building of a world leading facility for materials research.
Besides attractive employment and relocation conditions, the flexibility to balance work life with private life and good opportunities to further enhance your skills; you will also enjoy being part of an organisational culture that promotes and supports internal career growth.
We pride ourselves in having successful collaboration across different functions, and as the facility continues to grow we will keep nurturing the international and vibrant environment welcoming people from all across the world.

Duration & Location
The position is permanent with six months initial probationary period. Your work place will be situated in Lund, Sweden. The position is to be filled as soon as possible.

Application & Contact
Please provide your curriculum vitae and covering letter in English by clicking on “apply” and following the instructions. Please note we only accept applications via the ESS website.

The recruitment process is ongoing and the position is open until filled. Therefore we recommend that applications be submitted as soon as possible. Applications will be reviewed periodically.

For further information regarding the position, please contact Group Leader Neutron Optics and Shielding, Phil Bentley, phil.bentley[at]esss.se. For further information regarding the recruitment process, please contact HR Officer, Charlotta Olsson, charlotta.olsson[at]esss.se.

We look forward to receiving your application.

The European Spallation Source ESS AB will design, build and operate a multi-disciplinary, large-scale research infrastructure based on the world’s most powerful neutron source. ESS will provide scientists with unique and powerful neutron scattering instruments for the study of a large range of materials – from polymers and pharmaceuticals to membranes and molecules. The ESS project is partnered by 17 European countries, and hosted by Sweden and Denmark. The ESS will be built in Lund, Sweden, by a collaboration of European scientists and engineers. ESS is planned to produce the first neutrons by 2019. When the facility is in full operation 2025, ESS has around 450 employees.

ESS aim to ensure that staff are employed on the basis of ability and the requirements of the job, and that no applicant or employee receives less favourable treatment because of race, religion, ethnic origin, gender, sexual orientation or disability.
