Available in PDF, EPUB and Kindle. Book excerpt: ATLAS, a multi-purpose detector built at the LHC at CERN, requires an extensive commissioning campaign to be ready for proton-proton collisions. In this work, we focus on the commissioning of the liquid Argon (LAr) calorimeters, with emphasis on commissioning with cosmic rays. First we outline one phase of the commissioning work, which involves testing of the front-end electronics of the two endcap calorimeters. We then describe two cosmic ray generators as input to a Monte-Carlo simulation of cosmic rays in ATLAS, and compare their results. Finally, we explain a technique developed for this work which uses information from the Tile calorimeters to predict the timing of cosmic rays within the LAr calorimeters, because cosmic rays occur randomly in time whereas the electronics are clocked at 1/40.08 MHz. The results from this analysis tool are compared to default tools, using both simulated and real cosmic ray data in the calorimeters.

This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In preparation for the ATLAS experiment at the LHC at CERN. the high pseudorapidity region (|n| > 2.5) of the ATLAS end-cap liquid argon calorimeters underwent particle beam testing in 2004. One of the main goals of these tests is to study energy reconstruction in the complex interface region between the electromagnetic. hadronic, and forward calorimeters at. 1 - 3.2. These detectors were exposed to beams of electrons and pions with energies ranging from 6 GeV to 200 GeV. Three methods of calibration in the electromagnetic end-cap calorimeter (EMEC) are studied and compared to the results of a previous beam test. of the EMEC. The electromagnetic scale factor (aEM) is computed and compared to the previous beam test value. Studies of the energy response and resolution of the high pseudorapidity region of the three end-cap calorimeters to the particle beam position scans are given.

Download or read book Astroparticle, Particle And Space Physics, Detectors And Medical Physics Applications - Proceedings Of The 11th Conference On Icatpp-11 written by Pier-giorgio Rancoita and published by World Scientific. This book was released on 2010-04-30 with total page 950 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exploration of the subnuclear world is done through increasingly complex experiments covering a wide range of energy and performed in a large variety of environments from particle accelerators, underground detectors to satellites and space laboratory. The achievement of these research programs calls for novel techniques, new materials and instrumentation to be used in detectors, often of large scale. Therefore, fundamental physics is at the forefront of technological advance and also leads to many applications. Among these, medical applications have a particular importance due to health and social benefits they bring to the public.
Book Synopsis The Read-Out Controller ASIC for the ATLAS Experiment at LHC by : Stefan Popa
Download or read book The Read-Out Controller ASIC for the ATLAS Experiment at LHC written by Stefan Popa and published by Springer Nature. This book was released on 2022-12-17 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the complete chain from specifications to real-life deployment of the Read Out Controller (ROC) ASIC for the ATLAS Experiment at LHC, including the design of the FPGA-based setup used for prototype validation and mass testing of the approximately 6000 chips. Long-lasting experiments like the ATLAS at the LHC undergo regular upgrades to improve their performance over time. One of such upgrades of the ATLAS was the replacement of a fraction of muon detectors in the forward rapidities to provide much-improved reconstruction precision and discrimination from background protons. This new instrumentation (New Small Wheel) is equipped with custom-designed, radiation-hard, on-detector electronics with the Read Out Controller chip being a mission-critical element. The chip acts as a clock and control signals distributor and a concentrator, buffer, filter and real-time processor of detector data packets. The described and deployed FPGA-based test setup emulates the asynchronous chip context and employs optimizations and automatic clock and data synchronization. The chip's tolerance to nuclear radiation was evaluated by recording its operation while controlled ultrafast neutron beams were incident to its silicon die. Predictions for the operating environment are made. A proposed implementation of an FPGA Integrated Logic Analyzer that mitigates the observed limitations and constraints of the existing ones is included.

This book was released on 2010-01-11 with total page 1010 pages. Available in PDF, EPUB and Kindle. Book excerpt: CIPANP 2009 explores areas of common interest between nuclear physicists, high energy (particle) physicists and astrophysicists. These areas range from studies of the strong interactions that bind nuclei together to physics of the very early Universe and include such topics as neutrinos, hadron physics, spin physics, heavy ion physics, QCD and heavy flavor physics. The Conference papers include descriptions of searches for "new physics", phenomena that cannot be accounted for by current theories.

Book Synopsis Physics with Photons Using the ATLAS Run 2 Data by : Stefano Manzoni
Download or read book Physics with Photons Using the ATLAS Run 2 Data written by Stefano Manzoni and published by Springer. This book was released on 2019-08-02 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this book is based on the proton-proton collision data from the Large Hadron Collider at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector in 2015 and 2016. The research program of the ATLAS experiment includes the precise measurement of the parameters of the Standard Model, and the search for signals of physics beyond the SM. Both these approaches are pursued in this thesis, which presents two different analyses: the measurement of the Higgs boson mass in the di-photon decay channel, and the search for production of supersymmetric particles (gluinos, squarks or winos) in a final state containing two photons and missing transverse momentum. Finally, ATLAS detector performance studies, which are key ingredients for the two analyses outlined before, are also carried out and described.

It features the various aspects of a broad spectrum of activities needed to arrive at the physics results. The book includes also an outlook to the detector upgrade activities preparing the experiment for the high-luminosity LHC phase of the next decades. Last but not least, it reveals the human aspects of the large ATLAS community working together pursuing common physics goals.The book is aimed at a broad readership with interest in large science projects and their history, as well as in the human endeavour of a worldwide collaboration.
Book Synopsis Masking Problematic Channels in the Liquid Argon Calorimeter for the High-level Trigger of ATLAS. by :
Download or read book Masking Problematic Channels in the Liquid Argon Calorimeter for the High-level Trigger of ATLAS. written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Read-out channels in the liquid argon (LAr) calorimeter of the ATLAS detector are susceptible to various kinds of faults, which can impair the selection of events made by the trigger system. General-purpose software tools have been developed for dealing with problematic calorimeter channels. In order to give High-Level Trigger (HLT) algorithms robustness against detector problems, these tools have been applied in the HLT calorimeter data preparation code to mask problematic channels in the LAr calorimeter. Timing measurements and optimizations have been conducted to assess and minimize the impact of these operations on the execution speed of HLT algorithms. The efficacy of the bad-channel masking has been demonstrated using cosmic-ray data.
