A Beam Separation and Collision Scheme for IP2 and IP8 at the LHC for Optics Version 6.1

In this report we describe the proposed beam separation and collision schemes for interaction points 2 (ALICE experiment) and 8 (LHCb) in the LHC for optics version 6. The original proposal for optics version 5 was redesigned to be compatible with new requirements and the existing hardware. Contrary...

description In this report we describe the proposed beam separation and collision schemes for interaction points 2 (ALICE experiment) and 8 (LHCb) in the LHC for optics version 6. The original proposal for optics version 5 was redesigned to be compatible with new requirements and the existing hardware. Contrary to the original scheme, in our scenario some magnets in the common part of the two rings are used to establish part of the separation. However, individual control of the two beams remains fully possible. The necessary corrector strengths are significantly smaller and the aperture requirements less severe. Furthermore, this new scheme would allow to further increase the crossing angle, if required. To achieve this, the compensation scheme of the spectrometer magnets in IP2 and IP8 had to be redesigned and the implication of the desired alignment of these magnets was studied.
