The preliminary program for high energy physics in China

This paper is described on a future program for high energy physics in China. During the coming five years, the first high energy machine will be constructed to perform the first series of experiments in high energy physics in China, and the first nuclei of experimental high energy physicists and machine designers and builders would be formed. During the second five years, the first research center with the next machine would grow up. A proton synchrotron was chosen as the first high energy accelerator. The energy of the proton machine was decided to be 50 GeV. A proton linear accelerator of 200 MeV is to serve as its injector. The intensity of the beam might be about 1013 protons per pulse. The injection energy of the proposed machine was chosen so as to leave the option open to install a booster at a later date. It was decided that negative ions would be accelerated in the linear accelerator to achieve high beam intensity. Preliminary discussion concerning the experiments to be carried out at the new facility was made. (Kato, T.)
