    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.
