LHC last 1232 superconducting dipole for the LHC

Статус ускорителя LHC last (1232) superconducting dipole for the LHC was delivered on 27 November 3

План работы ускорителя LHC в 2007 • Beam pipe closes (ATLAS) - конец Августа 2007(? ? ) • NO ramp of beam to higher energies foreseen, stay at 450 Ge. V per beam (= injection energy from SPS) • collisions @ 450 Ge. V + 450 Ge. V until end of 2007 • shutdown to commission remaining LHC sectors to 7 Te. V without beam • physics running with significant luminosity at high energy in 2008 • Totally 6 weeks beam time in 2007 (calibration run): • 3 weeks – beam commissioning • 3 weeks collision 4
