The research area of the department is the advancement of controlled fusion energy production: develops and builds plasma diagnostic and technology systems, performs and evaluates measurements on the world’s largest fusion experiments.  Due to the technical-related activities, the staff is composed of physicists and engineers and can perform research and development tasks from physics modeling to engineering design and construction.

The major activities are the following:

  • Cryogenic pellet production, acceleration and interaction with the plasma. The laboratory operates the Shattered Pellet Injector (SPI) test laboratory for the ITER experiment where SPI technology is developed for ITER. Measurements are performed on pellet-plasma interaction on Wendelstein 7-X, ASDEX Upgrade and TJ-II.
  • Plasma diagnostics using video cameras and Beam Emission Spectroscopy. The laboratory has original technology for real-time video camera system, alkali beam injectors and observation systems. These are used on large international fusion experiments (Wendelstein 7-X, JET, MAST Upgrade, ASDEX Upgrade, EAST, KSTAR, JT-60SA) to study various plasma phenomena. 
  • Design of the Demo Oriented Early Neutron Source (DONES). The laboratory develops elements of the test cell, lithium loop and performs system engineering work.
  • Conceptual design of the European fusion DEMO reactor: engineering analysis for remote handling of large components, development of optical diagnostics and cryogenic pellet injection technology.
  • Modelling activities for beam-plasma interaction, fast particles in fusion plasmas, cryogenics pellet formation
  • 3D printing of fusion device models, technology components. In collaboration with ITER the department developed a 3D printable model of the ITER device.
  • Based on Beam Emission Spectroscopy technology the department is developing a 35 keV proton source as the input beam to accelerator  driven compact neutron generators.
