Description
The Pierre Auger Observatory is conceived to study ultra-high-energy
cosmic rays from about 10^17 eV to beyond 10^20 eV. It is a
multi-hybrid Observatory comprising 1660 surface detector stations
spread over an area of 3000 km^2 overlooked by 27 fluorescence
telescopes located at four sites at its periphery.
Phase I of data-taking spanned from its beginning in 2004 to the end
of 2022, producing a plethora of scientific results. Phase II
followed, featuring an upgraded Observatory with additional detectors
and faster, more powerful electronics, enabling the exploration of new
questions in ultra-high-energy physics.
The triggering system of the Observatory in the Phase I will be
described and compared with the new capabilities of the upgraded
Observatory in the Phase II of operations.
