SHIELD程序靶设计的实用化及其在W靶参数设计中的应用

Improvement on Design of Target by the SHIELD Code and It's Applications to Some Complicated Spallation Targets

将ＧＥＡＮＴ３．２１中的几何设计和图示技术移植到ＳＨＩＥＬＤ程序中，并在此基础上对几种具有复杂构造的Ｗ靶进行参数设计的初步研究．

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.
