| Research Abstract |
The Standard Model is the unique established theory in the elementary particle field. As a major element of this theory, an existence of the Higgs field is required. The Higgs field explain the origin of masses of quarks, leptons and gauge bosons. At least one type of the Higgs particle is predicted to exist in the energy-mass range of 1 TeV. A detector called ATLAS is constructed with international collaboration in order to aim at the discoveries of new particles such as Higgs and SUSY particles in the proton-proton interact ions using the LHC accelerator to be completed in 2007 at CERN, the European Particle Laboratory. The Japanese team has been in charge of following items : (1) Development and construction of 1200 units of muon trigger chambers (TGC), (2) Development of read-out and Level-1 trigger system of the muon trigger chambers and constriction of components for 320K channels, (3) Design and construction of 400K channels of time to digital conversion chips for muon drift tubes, (4) Design, Construction, Transportation, installation and excitation test of the Superconducting Solenoid for ATLAS, (5) Development of radiation-hard Silicon microstrip sensors and construction of 980 modules together with design and fabrication of special module mounting robots, (6) R＆D of data acquisition system for ATLAS and construction of simulation tools as well as physics studies of LHC events.
At the start time of the current Grant-in-Aid, LHC project was to be completed in 2005. However, the project has been delayed by 2 years in 2003. Accordingly some parts like installation and commissioning of the components that Japanese group is in charge of are somewhat delayed by about 2 years. However, the main goals of the current Grant-in-Aid were accomplished along with the original plans with a few exemptions.
