The construction of the Large Hadron Collider at CERN has been finished and ready for operating in 2008. It will contribute to the development of both experimental and theoretical physics, hosting new discoveries in particle physics. In this work we have reviewed the ATLAS detector which is one of the four main particle detectors at CERN and we reviewed also the Transition Radiation Tracker(TRT) which is one of the subdetectors of ATLAS. And at the last we have presented our work concerning the TRT Monitoring.
