The defeated Titans were then cast into a shadowy underworld region known as Tartarus. Atlas, one of the titans who fought against Zeus, was punished by having to hold up the sky. After the battle with the Titans, Zeus shared the world with his elder brothers, Poseidon and Hades, by drawing lots: Zeus got the sky and air, Poseidon the waters, and Hades the world of the dead (the underworld). The ancient Earth, Gaia, could
ZEUS (particle detector) in 1992. The last electron–proton collisions at ZEUS were recorded on 30 June 2007. The other multi-purpose experiment at the HERA collider was the competing H1 experiment. Since May 2012, the former ZEUS detector hall has been used as a lab space for the international European XFEL project. The main components of the ZEUS detector were the tracking components, the calorimeter and the muon detectors. The ZEUS Calorimeter was a uranium scintillator based sampling calorimeter and divided into 3 main sections: the BCAL (Barrel CALorimeter), FCAL (Forward CALorimeter), and RCAL (Rear CALorimeter). Each section was subdivided transversely into towers, and
