On July 17th, 2009, the Upgrade Project of the Beijing Electron Positron Collider (BEPCII) successfully passed the National Acceptance Test organized by the National Development and Reform Commission (NDRC), which marked the successful completion of the Upgrade on schedule, within budget and at high quality.

　　32 experts of the National Appraisal Panel, representing NDRC, the Ministry of Science and Technology, the State Archives Bureau, the National Natural Science Foundation of China (NSFC), the Beijing Municipal People's Government and the Chinese Academy of Sciences (CAS) , attended the acceptance meeting in the afternoon.

　　An on-site test was first organized, and was then followed by extended discussions. The Panel unanimously agreed that the BEPCII had reached the specifications of the national acceptance test, and concluded that its commissioning over the past six months had proved that it had become an advanced collider in the t charm energy region and in the study of new physics, and a synchrotron radiation facility of high performance. In terms of the collider, by adoping the most advanced double-ring alternating colliding technology, the BEPCII maintained its leading position in the world.

　　Right after this national test, the BEPCII will be soon dedicated to high energy physics experiments, and to SR users' experiments as well.
