Researchers using the Hadron Electron Ring Accelerator
(HERA) in Hamburg, Germany, have discovered that a proton exhibits a peculiar sort of lumpiness that apparently doesn't correspond to individual quarks or gluons.
His work includes experiments in the 25-inch and 40-inch bubble chambers at LBL and SLAC, work on the electron ring accelerator
at LBL, pion and kaon form factor experiments at Fermilab, the Time Projection Chamber (TPC) at Berkeley/SLAC, the D0 experiment at Fermilab, the CMS experiment at CERN, the DREAM calorimeter tests at CERN, and numerous smaller physics and instrumentation studies.
This facility, located in Hamburg and known as the Hadron Electron Ring Accelerator
, will be the world's first high-energy electron-proton collider.
