Lay Summary (German)

Lead
Der Large Hadron Collider (LHC) am CERN erzeugt Kollisionen von Protonen bei höchsten Energien. In einer sehr erfolgreichen Datennahmeperiode 2010-2013 wurden bei Energien von 7-8 TeV an die 20/fb an Daten genommen, eine Datenmenge, die etwa 250 PetaBytes an Daten entspricht. In der zweiten Datennahmephase des LHC, die im Frühjahr 2015 beginnt, werden Kollisionsdaten bei Schwerpunktsenergien von 13-14 TeV aufgezeichnet. Dieses FLARE Gesuch dient der Unterstützung von Forschungsprojekten am CMS Experiment, an welchem Forscher der ETH Zürich, der Universität Zürich und dem Paul Scherrer Institut (PSI) involviert sind.
Lay summary

Das Compact Muon Solenoid Experiment am Large Hadron Colliders (LHC) des europäischen Zentrum für Teilchenphysik CERN ist eines der beiden grossen Mehrzweckexperimente, die das Higgsboson im Jahre 2012 entdeckt haben und nach neuer Physik jenseits des Standardmodells der Teilchenphysik fahnden. Die Beiträge Schweizer Forschungsinstitute am Bau des CMS Experiment waren massgeblich, insbesondere beim Bau des elektromagnetischen Kalorimeters (ECAL)  und des Barrel Pixel-Vertexdetectors (BPIX).  Um das CMS Experiment über die nächste Dekade bezüglich seines Entdeckungspotentials optimal ausnützen zu können, müssen Infrastrukturinvestitionen gemacht und technische Unterstützung bereitgestellt werden. Dieses FLARE-Gesuch unterstützt Schweizer Forscherinnen und Forscher der ETH Zürich, des Paul-Scherrer Instituts, und der Universität Zürich in verschiedenen Bereichen:

(A) Die Strahlenbelastung und hohe Strahlluminosität des LHC in seiner "Phase 1" Ausbaustufe wird einen Ersatz des Pixeldetektors Ende des Jahres 2016 nötig machen. Schweizer Wissenschaftlerinnen und Wissenschaftler arbeiten im Kontext eines internationalen Konsortiums (aus Deutschland, Italien, Taiwan und den USA)  am Upgrade des Pixeldetektors. Die Aufgaben der Schweiz sind die Entwicklung des Auslesechips (ROC), der Modultests für die inneren zwei Lagen sowie an der mechanischen Integration. Im Zeitraum des Gesuchs wird die Massenproduktion der Module fuer die beiden inneren Lagen des Pixeldetektors fallen. 

(B) In einem zweiten Projekt werden die Bedürfnisse an computer hardware und technischer Unterstützung adressiert, die nötig sind für die Datenanalyse.

(C) Ein drittes Projekt unterstützt den Betrieb des ECAL Detektors

(D) und (E) Zwei Projekte beschäftigen sich mit grundlegender Forschung und Entwicklung zum "Phase 2" Ausbaustufe des ECAL und des Pixeldetektors. Diese ist im Jahre 2022 geplant. Wichtige Weichenstellungen für dieses Projekt sind im Gesuchszeitraum zu erwarten.

Abstract

The Compact Muon Solenoid (CMS) detector at CERN is one of two general-purpose experiments at the Large Hadron Collider (LHC). It is designed to measure the energy of photons, electrons, taus, and jets, the momentum of electrons and muons and other charged particles with high precision, and to provide precision vertexing capable of identifying heavy objects decaying with a displaced vertex. These measurements result in the reconstruction of all final states in the Standard Model and beyond, with excellent mass resolution for reconstruction of particles within new physics scenarios. The CMS experiment allows particle physicists from all over the world to address important physics questions like the origin of mass of fundamental particles and the existence of new forces and particles, such as those predicted by supersymmetric theories or extra dimensions. The contributions of Swiss institutions and funding agencies to the construction of the CMS detector have been highly significant, most notably in the electromagnetic calorimeter (ECAL) and the pixel vertex detector sub-components. These investments span more than 15 years of intense detector R&D and hardware development as well as engineering and construction. During this period, Swiss scientists have become world leaders in the respective detector technologies. Since 2010, the LHC has provided high quality, high statistics data sets using proton-proton collisions at the highest center of mass energies of 7-8 TeV ever reached by a man-made particle accelerator, creating opportunities for important discoveries at the high energy frontier. Commensurate with the large investments made by the funding agencies and CMS institutions of Switzerland, Swiss scientists from ETH Zurich, Paul Scherrer Institute and the University of Zurich, led by the six principal investigators signing this proposal, are playing highly visible roles in the physics exploitation of these datasets acquired with CMS, most notably in the recent discovery of a Higgs particle, but also in searches for physics beyond the Standard Model, such as Supersymmetry, and precision Standard Model measurements. The funding for academic personnel afforded by the respective SNF base grants of the PIs has proven to be crucial for these successes. For the continued exploitation of the CMS experiment, infrastructure investments and technical support for high performance computing as well as engineering support for highly efficient detector operations are indispensible. Furthermore, the physics potential of the LHC will allow for a rich particle physics program for at least the next 15 years to come: an increase in energy in early 2015 will access higher mass particle states, and higher luminosities starting in 2022 will allow for various precision tests and extend the reach for new physics further. In order to ensure the best physics exploitation of the ever-improving LHC capabilities in a correspondingly harsh radiation environment, the LHC detectors need to be upgraded, in a first (Phase-I) step at the end of 2016 and in a second step around 2021 (Phase-II). The proponents of this FLARE proposal have joined forces in order to ensure their commitments to the CMS experiment in operations and computing, and to engage in design and construction as well as R&D studies towards upgrades of CMS sub-detectors.This proposal presents a well-balanced portfolio of subprojects dedicated to these aforementioned tasks. In particular, subproject A is dedicated to the construction of a Phase-I upgrade of the barrel pixel detector to be commissioned at the end of 2016. Swiss scientists play a leading role in an international consortium of CMS collaborators dedicated to this Phase-I pixel detector upgrade. Subproject B deals with the demands on high performance (TIER3) computing infrastructure needed to perform cutting-edge data analysis and the necessity for moderate upgrades to cope with the ever-increasingly large datasets. Subproject C is dedicated to the maintenance and continuous improvement of the ECAL detector control system which is indispensable for high efficiency data taking. Subprojects D and E present basic research and development studies aimed at the technologies needed for the CMS Phase-II detector upgrade for the tracking and calorimeter system, respectively. Such activities are very timely since the development of such new technologies may need a persistent research effort over many years. The proposal furthermore presents a detailed business plan of these activities for the period 2014-2017, including estimates for required resources and detailed project milestones.
