Mitigating Radiation Loads in Nb3Sn Quadrupoles for LHC Upgrades
نویسنده
چکیده
Challenging beam-induced energy deposition issues are addressed for the next generation of the LHC high-luminosity interaction regions based on Nb3Sn quadrupoles. Detailed MARS15 Monte Carlo energy deposition calculations are performed for various coil diameters, thicknesses and materials of the inner absorber at a field gradient of 200 T/m. It is shown that using the inner absorber made of tungsten-based materials can make the final focus superconducting quadrupoles compatible with a luminosity of 1035 cm−2s−1.

Aperture Limitations for 2 Generation Nb3sn Lhc Ir Quadrupoles1
1 Work supported by the U.S. Department of Energy * [email protected] Abstract One of the straightforward ways towards the higher luminosity in the LHC is a replacement of the present 70mm NbTi quadrupoles with Nb3Sn quadrupoles which would provide the same field gradient but in a larger aperture. Conceptual designs of such magnets with 90 mm aperture have been developed and studied. This paper d...
متن کاملLow-β Quadrupole Designs for the Lhc Luminosity* Upgrade
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 supe...

CERN has encouraged the US-LARP collaboration to participate in Phase I of the LHC luminosity upgrade by analyzing the benefits gained by using Nb3Sn technology to replace the functionality of select NbTi magnets that CERN is committed to construct. Early studies have shown that the much higher gradients (shorter magnetic lengths) and temperature margins (quench stability) of Nb3Sn magnets comp...

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 ...
