Low-β Quadrupole Designs for the Lhc Luminosity* Upgrade
نویسندگان
چکیده
Several scenarios are considered for the upgrade of the LHC insertions in view of increasing the luminosity beyond 10 cms. In the case of “quadrupole first” option, superconducting low-β quadrupoles with apertures in the range of 90-110 mm are required in view of increased heat loads and beam crossing angles. We present possible low-β quadrupole designs based on existing Nb3Sn and LHC NbTi superconductors, present scaling laws for the magnet parameters and discuss relative advantages of the underlying triplet layouts.

Possible Quadrupole-first Options with Β ≤ 0.25m
A global model of an LHC insertion was prepared for the Arcidosso workshop. Its objective is to evaluate in a consistent way the potential of a class of solutions for the LHC low-β upgrades and help identifying what should be the R&D lines. The solutions studied are those of the present LHC baseline layout, namely quadrupole first and small crossing angle. Provision for dipole first solutions i...
متن کاملInvestigations of the Parameter Space for the Lhc Luminosity Upgrade
Increasing the LHC luminosity by a factor of ten is a major challenge, especially for the beam-beam long-range interactions and even more for the magnet technology and insertion layout. To help identifying consistent solutions in this multi-dimensional constrained space, a parametric model of an LHC insertion was prepared, based on the present LHC layout, i.e. “quadrupole first” and small cross...
متن کاملScenarios for the LHC Upgrade
The projected lifetime of the LHC low-beta quadrupoles, the evolution of the statistical error halving time, and the physics potential all call for an LHC luminosity upgrade by the middle of the coming decade. In the framework of the CARE-HHH network three principal scenarios have been developed for increasing the LHC peak luminosity by more than a factor of 10, to values above 10 cm−2s−1. All ...
متن کاملATLAS Upgrade for the Super LHC Meeting the challenges of a ten-fold increase in collisions
With the Large Hadron Collider (LHC) about to start collisions, plans are already advancing for an upgrade. In this super-LHC (sLHC) project, about ten times the LHC luminosity in some 8 years from now is aimed. Coping with the high instantaneous and integrated luminosity will require many changes to the ATLAS detector. The designs are developing rapidly for an all-new inner-tracker, big change...
متن کاملLhc Luminosity and Energy Upgrade*
LHC upgrade studies are ongoing as part of the EU CARE-HHH and of the US-LARP programmes. The aim is a ten-fold increase of the LHC luminosity by the middle of next decade, a possible upgrade of the injector complex to inject at 1 TeV and, at a later stage, to raise the collider energy. The motivations for the LHC upgrade are discussed. An overview of beam dynamics and technological challenges ...
