The Milešovka mountain hosts a long-term measurement campaign as part of the BIOSPHERE project. It involves 22 international scientific institutions that receive funding from the European Metrology Partnership, co-funded by the EU’s Horizon Europe research and innovation programme and the participating countries.
The BIOSPHERE training course and the 1st stakeholder workshop on “New methodologies and developments to investigate the influence of extraterrestrial radiation in the biosphere” was organized by UJF CAS, CMI, and PTB on October 1-2, 2024, in Prague and at the Milešovka observatory, Czech Republic. The event attracted over 50 participants, including both in-person and online attendees.
The course focused on new methods and techniques developed within the project, specifically on methods capable of identifying and establishing correlations between cosmic rays, solar UV radiation, and the thickness of the ozone layer, as well as assessing their mutual effects on biological systems.
Taking advantage of the ongoing third measurement campaign at the Milešovka Observatory (running from mid-August 2024 to mid-November 2024), participants were provided with a unique opportunity to see the instruments in action.
The first day featured lectures introducing key topics, including an invited presentation by Prof. Ashot Chilingarian, head of Cosmic Ray Division (CRD) at the A.I. Alikhanyan National Laboratory (Yerevan Physics Institute), titled “Modulation of Cosmic Rays in the Earth’s Atmosphere”. On the second day, participants joined an excursion to the Milešovka Observatory, where they observed the instruments in operation and received on-site explanations of their functionality. Prof. Chilingarian also presented the SEVAN detector installed at the observatory, part of the SEVAN network.
The topic of the project and the third measurement campaign captured significant media interest. Coverage included a report aired on Czech Television News and broadcasts on Czech Radio.
Muon tracking with miniaturized 2× stack Timepix3 telescope
The secondary cosmic radiation field during the 3rd measurement campaign at the Milešovka Observatory is measured in high resolution and enhanced resolving power with a miniaturized particle telescope 2× stack Timepix3.
Data is processed with previous calibration database, AI and pattern recognition algorithms using an integrated database and SW tool TraX Engine. The composition and spectral characterization of the mixed-radiation field is resolved into particle species. The resulting angular flux of muons measured on ground in the atmosphere is shown below.
