NEWS FROM THE FIRST HEAVY ION RUN
The LHC proton-proton programme stopped on Thursday 4.11.2010 at 8 am.
After a short access the commissioning of the lead ion beam started in the afternoon of Thursday 4.11.2010

Thursday 4.11.2010 16:43 It seems they have started injecting ions
Thursday 4.11.2010 after 22:00
Friday 5.11.2010 from 1:30 am on : two ion beams circulating in LHC
Saturday 6.11.2010 23:00 Two lead ion beams in LHC .. this fill is to find collisions
..they are ramping up the energy
Sunday 7.11.2010 1:00 the beams have been squeezed, the collimators adjusted..
2:40 Collimators settings ongoing. ALICE is taking data with the Silicon Detectors - the Time Projection Chamber is off since no "stable beams" have been declared..
50 000 events were recorded
