Abstract Objective To analyse the variation of eight kinds of eight kinds X-ray emitting efficiency with the target thickness and X-ray tube voltage transmission targets. Methods Keeping stable the target thickness and distance between source and detector, X-ray emitting efficiency of different target thickness is calculated by using the MCNP software for eight kinds of targets when the tube voltage is 10kV, 20kV,30kV,40kV,50kV,60kV. Results Maximum X-ray emitting efficiency and optimal target thickness is made certain for the eight kinds targets of 24Cr、29Cu、42Mo、45Rh、47Ag、74W、79Au、82Pb on six kinds of tube voltage. Conclusion X-ray emitting efficiency will increase at first and then decrease and it will to be maximized with the optimal target thickness. Emitting efficiency and optimal target thickness will increase with the increase of the tube voltage increase, but the would be different for different targets.
