1. Lecture II

2. LHC lay-out C = 26658.90 m Arc = 2452.23 m DS = 2 x 170 m
INS = 2 x 269 m
Free space
for detectors:  23 m

3. LHC features
Technological
challenge
(+1)

4. e* = m
Bunch spacing
25 ns m

5. Maximum B-field

6. Cos(q) coil

7. Superconducting dipole

8. Collider luminosity
High L needs:

9. Beam-beam interaction

10. Head-on collisions

13. LHC luminosity

14. LHC insertions
56 m

17. Beam power density Staged implementation of the collimation system
Learning process needed to reach % collimation efficiency required at full intensity (~70% efficiency required in the Tevatron)
Carbon-carbon collimator ok for phase 1, but insufficient for full intensity
Initial LHC luminosity reduced (x 3 ?)

19. High luminosity experiments

20. Ion-ion experiment
