| Abstract: | The technique of the geometric design and graphic displaying of GEANT3is adopted in the SHIELD code. Some examples of complicated spallation targetS aredesigned and discussed. With the proton beam energy of 150MeV, our results showthat the best thickness of W spallation target is scm, 5.0-5.8 neutrons can beproduced Per GeV of beam energy for properly designed W target the materialdamage and the radiation deposits are concentrated in the beam axes of about 2 cmlong, scattered proton beam may alleviate the concentration, but may also lower theneutron production. |
