Abstract：
The technique of the geometric design and graphic displaying of GEANT3 is adopted in the SHIELD code. Some examples of complicated spallation targetS are designed and discussed. With the proton beam energy of 150MeV, our results show that the best thickness of W spallation target is scm, 5.0-5.8 neutrons can be produced per GeV of beam energy for properly designed W target the material damage and the radiation deposits are concentrated in the beam axes of about 2cm long, scattered proton beam may alleviate the concentration, but may also lower the neutron production.
