ESS invites applications for a postdoctoral researcher position via the CREMLINPlus grant, at the ESS Detector facilities in Lund, from 1 November 2021 and until 30 October 2023 (2 years).

Job description

The successful candidate will be participating in the Multi-Blade detector technology project, led by Dr. Francesco Piscitelli. The primary focus of the work will be the successful completion of building a neutron detector for the PIK reactor in St. Petersburg, as part of the CREMLINPlus grant. The candidate will work closely with a team of various Mechanical Engineers and with other Detector Scientists and Technicians. This work is part of a collaboration with JINR – Dubna, PIK – St. Petersburg in Russia and the University of Milano-Bicocca – Italy. The work will be shared mostly between the ESS offices and the Detector Group workshops in Lund as required. You might also be given the opportunity to visit other collaborating partners and neutron centers, as necessary, in particular time may be spent at the different partner institutes. Mobility will be subject to the status of the pandemic and the employer’s respective guidelines.

To a lesser extent (30%) the successful candidate will work on generic and specific detector simulations as required, aimed at improving the detector design, in particular for instruments at PIK and ESS.

You will have varied, wide ranging responsibilities and duties that will include:

  • Contribute to the scientific development of the coming Multi-Blade prototypes. Contribute to the proposals for the mechanical engineering solutions.
  • Contribute to the assembly and building of the detector prototypes at the workshops. Participate in the procurement of parts.
  • Testing and verifying detector prototypes.
  • Monte Carlo simulations of detector and related instrument models. Production, installation and commissioning of the detector.

This is an opportunity to acquire and develop skills and be involved in the creation of a world-class facility. We are working with world leading partners to achieve something very special, to contribute to becoming a leading research facility.


We are looking for a self-motivated person, capable to work as part of a team and confident to expose and contribute with your own ideas. In particular, we are seeking knowledge, skills and competence on the following:

  • PhD degree in physics or similar, ideally in neutron instrumentation. Expert with particle detection, ideally of thermal neutrons.
  • Experience with preparing experimental setups for detector performance evaluation.
  • Data analysis and coding experience with python and C/C++, as well as code repositories. Knowledge in neutron scattering is an asset.
  • Experience with operation and debugging of detector readout electronics and data acquisition systems. Competence with standard Monte Carlo tools of the field, e.g. Geant4, is an advantage.
  • Experience with Linux operating systems (operation, installation).

Other requirements

  • A precise person, attentive to detail, striving for the upmost quality, always looking to refine methods and techniques to improve the deliverable.
  • Able to multi-task and to work to deadlines.
  • Able to adapt to new challenges and to develop novel solutions. Proven self-motivation and initiative.
  • Be a positive team player and work comfortably with different interfaces and stakeholders. Experience of working in an international research environment.
  • Ability to travel when required for the project, when restrictions caused by the pandemic are no longer an issue.
  • Excellent oral and written English skills are a prerequisite; knowledge of other European languages would be an advantage.

As a person, you must be a good listener and creative. You must be flexible in your approach to work and prepared to tackle a very wide range of tasks in order to ensure successful and timely delivery. You must be a hands-on person, strongly motivated by the desire to widen your knowledge on neutron detectors and deliver on time detector demonstrators. You must fit into our culture and share our values.

Duration and location

This is a temporary full time 2-year position ending in 30 October 2023 and based in Lund, Sweden.

Start date

The position is to be filled as soon as possible.
