2012 run
Extension of 2012 run approved by the DG on 3rd July 2012

3. LHC: end of 2012 physics period

4. ATLAS / CMS luminosity
Integrated luminosity in 2012 passed 20 fb-1 last week.
Fast luminosity ramp up was possible based on 2011 experience.
Peak L = 7.7×1033 cm-2s-1.
We expect to reach fb-1 by the end of the run.

6. Efficiency Average fill length: 6.0 hours
Average fill length comparable to 2011.
Fill length is determined mostly by MP system detecting parameters outside envelope and triggering a beam dump.
Spent 36% of scheduled time with stable beams.
Compared to 33% in 2011

7. Proton-Lead test and run
A test with 13 colliding p and Pb bunches was done end September with few hours of first p-Pb collisions.
A 4 week long run will be made in Jan/Feb 2013.
Expected beam parameters:
200 ns spacing proton and Pb beams,
~350 bunches / beam,
p in ring 1 + Pb in ring 2, and vice-versa,
Luminosity ~ 6x1028 cm-2s-1.
ALICE p-Pb event
