1. 1. A Central Rapidity Straw Tracker and Measurements on Cryogenic Components for the Large Hadron Collider

   Författare :Hans Danielsson; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; physical instrumentation; tracker; transsition radiation; LHC; cryogenics; superconducting; Metrology; helium; Metrologi; fysisk instrumentering; Fysicumarkivet A:1997:Danielsson; Fysicumarkivet A:1997:Danielsson;

   Sammanfattning : This thesis is divided into two parts in which two different aspects of the Large Hadron Collider (LHC) Project are discussed. The first part describes the design of a transition radiation tracker (TRT) for the inner detector in ATLAS. In particular, the barrel part was studied in detail. The barrel TRT consists of 52 544 1.

3. 2. The search for a standard model Higgs at the LHC and electron identification using transition radiation in the ATLAS tracker

   Författare :Ulrik Egede; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; Elementary particle physics; tracker; Large Hadron Collider; pion rejection; pattern recognition; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1998:Egede;

   Sammanfattning : The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. LÄS MER

4. 3. Characterisation of nystagmus waveforms in eye-tracker signals

   Författare :William Rosengren; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Eye tracking; Signal processing; Nystagmus;

   Sammanfattning : This thesis deals with the analysis of eye–tracker signals recorded from nystagmus patients. Nystagmus is an eye movement disorder caused by an underlying condition, and patients who suffer from nystagmus express involuntary oscillating eye move- ments. LÄS MER

5. 4. B-physics potential of the ATLAS experiment and performance of the ATLAS Transition Radiation Tracker

   Författare :Chafik Driouichi; Teoretisk partikelfysik - Geonomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; B-physics; LHC; Bc meson; Elementary particle physics; Transition Radiation Tracker; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2004:Driouichi;

   Sammanfattning : The ATLAS experiment is one of the four experiments at the Large Hadron Collider (LHC), which is supposed to be operational in early 2007. Proton-proton collisions at an unprecedented center-of-mass energy of 14 TeV will probe new frontiers of the universe, hopefully providing a better understanding of the laws governing our universe.

7. 5. Transition Radiation Tracker calibration, searches beyond the Standard Model and multiparticle correlations in ATLAS

   Författare :Alejandro Alonso; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beyond Standard Model; ATLAS; LHC; Fourth family of quarks; Same-sign top production; Drift tubes; TRT; QCD; Supersymmetry; Inner Detector calibration; Tracking;

   Sammanfattning : This thesis contains two different aspects of my research work towards physics in proton-proton collisions in the ATLAS experiment at the LHC. The first part is focused on the understanding and developing of a calibration system to obtain the best possible charged particle reconstruction in the Transition Radiation Tracker. LÄS MER
