1. Welcome at CERN and Practical information Jean-Paul Burnet 14-16 June 2010

2. Founded in 1954 by 12 countries Today: 20 member states 1000 MCHF / Year budget 2250 staff (physicists, engineers, technicians, …) 6500 visiting scientists (half of the world's particle physicists) They come from 500 universities representing 80 nationalities. 9000 people on CERN site everyday! Introduction to CERN

3. LHC first ramp to 1.08 TeV 29/11/2009 LHC first physics 30/03/2010

4. Where are we with LHC? 4  The machine is now working very well  at 3.5 TeV per beam(nominal 7 TeV)  with a di/dt at 2A/s(nominal 10 A/s)  Beam commissioning  beam 2.10 10 protons per bunch up to 13 bunches (over 2808)  intensity up to 10 11 protons per bunch (1,7.10 11 nominal)  squeeze (β*) up to 0.55m, working at 2m  LHC plan  LHC will run up to end of 2011  target for the integrated luminosities 1fb -1 end of 2011  2012 will be a large shut down for LHC consolidation (splices,…)

5. Progress with beam 5

6. Introduction to TE/EPC  The Group is responsible for all the magnet power supplies, klystron modulators (solid state) and static VAR compensators.  67 staffs + 20 people in industrial support, 22 engineers  ~ 5000 power supplies from 1 kW to 144 MW, from 10A to 30kA, from 8V to 110kV  Recurrent budget = 4 MCHF
