Researchers´ Night 2021

Mysterious, elusive and convoluted. That may sometimes be your impression of science, but not on Researchers’ Night! A night when science and scientists show you their true face.

For the fifth year, ELI Beamlines and HiLASE Centre will join this extraordinary event and open doors to the public for this great European celebration of science.

This year it will take place on September 24th 2021, 6 p.m. – 10 p.m.

The topic for Researchers’ Night 2021 is TIME.

A complete program is available HERE. A large part of our program will be held in Czech, but English-speaking visitors are also very welcome! You can try many different activities to discover the beauty of laser physics: interactive exhibits, virtual reality, LEGO workshops etc. You can enjoy this accompanying program for children and adults without registration.
A guided tour of ELI Beamlines laser centre in English will take place from 6.30 p.m. to 7.15 p.m. During this tour, you will be able to see ELI Beamlines high-power laser systems and receive a lot of information about ELI Beamlines technologies, research activities and a construction of the facility.

The Researchers’ Night has been held in the Czech Republic since 2005 and ELI Beamlines is not to be missed! Together with us, universities, institutes, observatories and other institutions join the event. In 2020, the coordinators (University of Ostrava and VŠB – TUO) succeeded in obtaining the prestigious European Marie Curie-Skłodowska project, thanks to which the Czech Researchers’ Night is also on the European map.
