THE CURRET STATUS OF BEPC

The progress of BEPC in thc past 8 month is described. The main civilengineering construction of the collider machine will soon be finished. Nearly70% of the components of the linac have been installed in the tunnel. Its first 8sections with an energy of 250 MeV have commissioned. A positron beam with anencrgy 100 MeV and a curreent intensity of 2.5 mA were obtained. Except theceramic window of the Rf cavity which is still in R & D stage, more than 90%non-standard components have been delievered to our institate. Testing is under-way. The installation of transport line was completed at the beginning of June,and the installation of the ring has startcd just now. The main parts of the con-trol system were established in our 1ab. The synchronous RAMP simulation wascompleted. The beam position monitor software is being debugged.
