|
A planned project CEPC-SPPC is under-researched by IHEP, CAS, China. Due to its big circumference and high energy, the radiation shielding issues should be treated more serious than ever whether for the machine itself or the worker and the public. In this paper, we briefly introduce the configurations and parameters of the machine, the tools and principle used in the radiation shielding design, and discuss the preliminary result for the shielding of main tunnel and the synchrotron radia-tion. Some radiation protection issues are listed to be resolved next. All the aspects presented should be dis-cussed and verified, any other unmentioned radiation protection problems will be excavated in the future.

| Massive experimental works are aimed to clarify the structure of detector including CT with X ray machine, determining the thickness of dead layer with collimating radioactive source and ect. Measuring structure and size of the detector by X-ray computed tomography, measur-ing the dead layer thickness of detector's front surface and side surface though collimated point source method, scanning the dead layer distribution of the entire detec-tor. A finite element analysis software name CST is used to simulate electric field distribution of the HPGe detec-tor. Calibrating the efficiency of HPGe detector by means of point source and soil standard matter, A Monte Carlo software called MCNP is used to simulate detector effi-ciency preliminarily according to the structure parame-ters of the factory, optimizing and verifying simulated results on the basis of measured results. At last, the com-parison of the simulated and the experimental data showed very good agreement. | ||
