Albert DeRoeck, CERN (IMAGE) Southern Methodist University Caption First collisions of protons at the world's largest science experiment are expected to start the first or second week of June, according to a senior research scientist with CERN's Large Hadron Collider in Geneva. See http://bit.ly/DIS_2015_SMU "It will be about another six weeks to commission the machine, and many things can still happen on the way," said physicist Albert De Roeck, a staff member at CERN and a leading scientist on CMS, one of the Large Hadron Collider's key experiments. De Roeck spoke to the worlds physicists at the XXIII International Workshop on Deep-Inelastic Scattering, Southern Methodist University, Dallas.
