Entry Level Detector Scientist - Beam Monitors

European Spallation Source ERIC
Lund, Sweden
Posting live until
14 Jun 2024

Job Details

Job description:

The European Spallation Source is one of the largest science and technology infrastructure projects being built today. The project includes the most powerful linear proton accelerator ever built, a five-tonne, helium-cooled tungsten target wheel, 15 state-of-the-art neutron instruments, a suite of laboratories, and a supercomputing data management and software development centre. 

About the role:

ESS is at an exciting turning point. It is in transition from being a construction site, to being an operating facility. To help us realise our goal of being the most powerful neutron source in the world, we are now looking to add an entry-level Detector Scientist for Beam Monitors to our Detector Group. As our next Beam Monitor Detector Scientist, you’ll be part of ESS's largest and most critical projects, and you'll play a pivotal role in delivering state-of-the-art neutron beam monitors for the cutting-edge ESS beam lines.

Working alongside world-class scientists, engineers, and technicians, you'll be at the forefront of in-house development and construction of detector systems. This interesting and unique role gives you the opportunity to develop and deploy novel neutron beam monitors and other detectors, participate in experimental campaigns to evaluate their performance, perform data processing and analysis, and conduct detector simulations. You'll also work on detector system integration, where you'll collaborate closely with engineers and technicians to ensure seamless integration. Additionally, you'll provide support during the installation, commissioning, and operation phases, ensuring the smooth functioning of the detector systems. This multifaceted role combines hands-on development, experimental work, data analysis, and system integration, offering a dynamic and challenging environment for you to thrive.

The position is for a fixed-term period of three (3) years and is based at the ESS Campus in Lund, Sweden, with frequent travels to other collaborating partners and neutron science centres for testing and evaluating beam monitors.

About you:

Our ideal candidate for this role will hold a PhD in physics or engineering and can demonstrate a strong academic background in the field. Your expertise should encompass detector instrumentation and detector R&D, particularly in gaseous detector technologies, although proficiency in other detector technologies will also be considered. While experience in neutron scattering and neutron detector technologies is advantageous, it is not mandatory. However, you should possess the hands-on practical skills necessary to prepare experimental setups for detector performance evaluation (including beam tests).

Proficiency in data analysis and programming is essential, with a preference for experience in Python and C/C++. Additionally, familiarity with detector simulation software such as GEANT4, GARFIELD++, FLUKA, etc., is highly desirable. Prior experience with finite element method software such as COMSOL or ANSYS is advantageous, but not a strict necessity.

The working language of ESS is English, and we need someone who can start as soon as possible.

What can we offer?

Aside from the chance to work on a truly unique big science project, you can also expect:

  • Market competitive compensation that is individual and differentiated according to role, responsibilities, individual skills, abilities, and achievements.
  • 30 days of annual leave, as well as more than 10 days of public holidays and company days off or days with limited working hours.
  • Monthly pension contributions on top of your salary.



The European Spallation Source, ESS, is a partnership of European countries, with its HQ in Lund, Sweden. Our vision is to build and operate the world’s most powerful neutron source, enabling scientific breakthroughs in research related to materials, energy, health and the environment, and addressing some of the most important societal challenges of our time.

ESS is hiring motivated and inspired people to design, construct and operate the world’s most powerful neutron source. We seek ambitious, talented people in different fields who are excited about playing a part in the future of science in Europe.

ESS can offer a variety of things, such as passionate and international colleagues, a vibrant melting pot of diversity, and a challenging, exciting and high paced work environment. We value and need expertise, innovative minds and great ways of leading and interacting with people from all over the world.
