摘　　要：主要介绍了北京正负电子对撞机上为提高同步辐射光源性能而设计建造的第一台真空内扭摆磁铁的概况 ,论述了真空内扭摆磁铁的设计要求和参数 ,以及研制过程中的关键技术和难度 。The general features of the first in-vacuum wiggler designed and constructed in Beijing Electron Positron Collider (BEPC) as a part of the BSRF upgrade project are introduced. The measured magnetic field of the in-vacuum wiggler reaches 2.0 Tesla when operated at the gap of 12mm, which will provide high flux in the hard X-ray region and will be mainly used for the high temperature and high pressure diffraction experiments. The key technologies and difficulties for the magnetic and mechanical design of the in-vacuum wiggler are described. The main parameters and the requirements for the in-vacuum wiggler are given too. Also, the magnetic field measurement results are shown.
