efforts were taken to build Time-of-Flight detectoif TOF) useing scintillating fibre. With Monte- Carlo methods , the main, elements that determined the time performance of TOF were explored , and comparation was made between TOF made of Sciiililaiiiig Fibres and that made of Plastic Scintillating bar. After this simulation study , optimization methods for Time Resolution of TOF was proposed. At last chapter , preliminary study on the 2-dimension image technology useing Scintillating Fibres
