Construction of the e–p collider HERA under way in Hamburg
DOI: 10.1063/1.2915908
Construction has begun at DESY on an electron–proton collider, the first of its kind in the world. This Hadron Electron Ring Accelerator, or HERA, will collide 820‐GeV protons with 30‐GeV electrons, providing 314 GeV in the center of mass. The proton storage ring uses 4.53‐T superconducting magnets. The electron storage ring, on the other hand, uses conventional technology. But the ring will produce longitudinally polarized electrons, a capability never achieved in a storage ring before. Because of this capability and its high center‐of‐mass energy, when HERA starts running experiments in 1990, it should shed new light on the weak interaction by charged and neutral currents with quarks
