About the project:

With the Large Hadron Collider (LHC) at CERN we entered a new era of research in High Energy physics. During its first years of operation the LHC has been proven very successful, culminating with the discovery of the Higgs boson. To fully take advantage of the potential of the LHC machine to make new discoveries, a series of upgrades is planned. First, the energy was increased from 8 to 13 TeV during 2017 and will be further increased to the full design energy of 14 TeV by 2021. Second, the beam intensity will be upgraded during two interruptions to regular LHC operation: first in 2019-2020, then again during 2024-2025. Since the intensity upgrades lead to 2-10 times higher collision rates delivered to the experiments (as well as higher radiation doses), the LHC experiments with Norwegian participation, ATLAS and ALICE, need to enhance their detectors, trigger systems, and computing systems accordingly. In this proposal we have addressed in a consistent way the infrastructure requirements for exploitation of the LHC luminosity upgrades. We apply for funding of the improvments to the ATLAS and ALICE experiments and the re-furbishing and expansion of the required e-infrastructure, thus securing Norwegian membership in these experiments and our position at several of the internationally recognized frontiers of high energy physics research. It is also a unique opportunity for Norwegian researchers to harvest the outcome of many years of detector R&D, which may result in new detector technologies. When ready, the HL-LHC will give unprecedented statistics at collision energies never before probed, which promises important new physics insight and possibly new discoveries.


The main objective is to enable the study of fundamental particles and interactions and the characterizaton of high-temperature strongly interacting matter at the extreme energies and collision rates of the upgraded Large Hadron Collider (HL-LHC) at CERN in the years 2017-2035. To achieve this we propose to contribute to upgrades of the ATLAS and ALICE experiments both in terms of detector hardware as well as computing infrastructure. By participating in upgrades for HL-LHC, which has the status of a Landmark on the ESFRI roadmap, Norway's memberships in the LHC experiments and our position at the frontiers of high energy particle and heavy ion physics will be secured.


This project is providing infrastructure for the HENP and HEPP projects of CERN-related research program.
