7. HL-LHC ARCHITECTURE & INSTALLATION DURING LS2

8. What about LS2? Marzia’s presentation
The LS2 project include the activities across the LHC, Injectors and LHC experiments:
Resources levelling across the accelerators  one of the main challenge of LS2 !!!
The activities will be declared in Plan, with a similar approval process as LS1.
Practical issues:
Temporary storage areas and “bases de chantier” will be installed at the earliest 6 months before, and dismounted at the latest 6 months after LS2;
Buffer zone availability: most probably the existing areas are not sufficient;

MB replaced by 3 cryo-assemblies, installed and aligned independently
11 T dipoles assembled with an angle of 2.55 mrad relative to each other and shifted by 0.8 mm towards the center of the LHC to minimize loss of mechanical aperture
Cryostat for the 11 T dipole following standard LHC design
Short connection cryostat: creates space for collimator and warm beam vacuum sector; continuity of powering and cryogenics along the LHC arc
Collimator: 0.8-m-long active part – tungsten – 1.34 m with transitions and expansion joints
RF-shielded gate valves allow for independent operation of cold and room temperature beam vacuum sectors
Example of integration on the left side of an interaction point (IP7 in this case), two main dipoles are replaced by four 11-T Dipoles, and 2 collimators
