Opis: At the Leading Edge - Dan Green

Too often descriptions of detectors focus on the what and not the why. This volume aims to elucidate how the requirements of the physics at the Large Hadron Collider (LHC) define the detector environment. In turn, the detector choices are made to adopt to that environment. The goal of LHC physics is to explore the mechanism for electroweak symmetry breaking. Because of the minuscule cross-sections which need to be explored, 0.1 fb, the LHC needs to provide 100 fb-1/yr, or an instantaneous luminosity of 1034 / (cm2 sec). With a bunch crossing interval of 25 nsec, well matched to detector speeds, there will be 25 events occupying each bunch crossing. Thus the physics requires fast, finely segmented, low noise and radiation resistant detectors which provide redundant measurements of the rarely produced electrons and muons. To achieve those goals, new ground was broken in constructing the A Toroidal LHC Apparatus (ATLAS) and Compact Muon Solenoid (CMS) detectors in the vertex detectors, tracking systems, calorimetry, strong magnets, muon systems, front end electronics, trigger systems, and in the data acquisition methods used. The book contributes in an impressive way towards understanding the motivation behind specific choices, and towards learning about the risks and the courage required to tackle necessary technological developments. -- CERN Courier "CERN Courier"Introduction: How Physics Needs Define the LHC Environment (D Green); The ATLAS Pixel Detector - Technical Challenges at Small Radius (K Einsweiler); The CMS Pixel Detector (W Erdmann); The Hybrid Tracking System of ATLAS (L Rossi); The Silicon Strip CMS Tracker - Micro Technology at the Macro Scale (M Mannelli); The ATLAS Electromagnetic Calorimeters - Features and Performance (L Mandelli); The CMS ECAL - Particularly Crystals and Photosensors (P Bloch); TileCal - The Hadronic Section of the ATLAS Calorimeter (R Stanek); Readout Innovations for the CMS HCAL (J Freeman); ATLAS Superconducting Toroids, the Largest Toroids Ever Built (H H J ten Kate); Constructing a 4T Solenoid at the Limit of the Possible (A Herve); The ATLAS Muon Spectrometer (G Mikenberg); The CMS Muon Detector - From Early Thoughts to the Final Design (F Gasparini); ATLAS Electronics - Challenges and Achievements (P Farthouat); Innovations in the CMS Tracker and ECAL Electronics (G Hall); The Why and How of the ATLAS Data Acquisition System (L Mapelli); Removing the Haystack - The CMS Trigger and Data Acquisition Systems (V O'Dell).
