Apply

The European Spallation Source (ESS) in Lund, Sweden is a partnership of 13 European countries with the mission to design, construct and operate the world’s most powerful neutron source.

Working with us means being part of a challenging and exciting work environment, at a stunning, brand new workplace filled with innovative minds and brilliant people from across the globe.

About the position
We are now looking to appoint a summer worker for the Cryogenics group in the Accelerator Division.

The Cryogenics Group works alongside other groups in the Accelerator Division to define, design, install, commission and finally operate and maintain the cryogenic systems of the ESS. These efforts extend also to cryogenic needs in the Target Division and the Science Directorate.

The ESS cryogenic systems are currently in commissioning phase. Performance tests are being conducted on key components, including circulation hydrogen pump, heat exchanger, expansion turbine, catalyst, control valve, flow meter, as well as overall system performance tests. These tests aim to verify the cryogenic system design and to optimize operational conditions, leading to the establishment of an automatic control system. Additionally, ESS has developed a high-accuracy Raman optical system to measure the parahydrogen fraction at 17 K.
