Crystal Ball to move from SLAC to DESY

JAN 01, 1982

The German Electron Synchrotron laboratory (DESY, Hamburg) and SLAC have agreed to a unique intercontinental transfer of a major high‐energy‐physics detector facility. After more than three years of fruitful operation at SPEAR, the older of the two electron–positron storage rings at SLAC, the “crystal‐ball” particle detector will be moved in June to DORIS, SPEAR‘s opposite number at DESY. The 730 sodium‐iodide crystals that make up the seven‐foot‐diameter hollow crystal ball provide extra‐ordinary energy resolution for high‐energy photons (PHYSICS TODAY, July 1981, page 21).
