An electron-positron collider, VEPP-2000, aims at achieving a maximum luminosity of 2 x 10^<32>cm^<-2>s^<-1> up at 1 GeV per beam, by having round beam collisions between electrons and positrons. Data of hadroninc production by electron-positron collision between 1.4 and 2.0 cms energies are relatively scarce ; if this VEPP-2000 can achieve its design luminosity, experiments using VEPP-2000 will make it possible to understand fundamental processes and contribute much to the advancement of high-energy physics.Round-beam collisions are essentially in one dimension due to their symmetry, and it can be expected that this 1-dimensional feature makes non-linear effect at beam-beam collision substantially weak. Computer simulation done by BINP-KEK collaboration really shows that VEPP-2000 machine will reach its luminosity goal by careful and fine tuning of its operation points.Due to the limitation of available area that houses VEPP-2000, magnets should have high magnetic field. Especially, this machine needs to have two pairs of 13 tesla superconducting solenoid magnets, which are essential to create round beams.The construction of VEPP-2000 has been completed in spring of 2007 and its commissioning has started. In a few years it will produce much physics results.

电子-正电子对撞机 VEPP-2000 旨在通过电子之间的圆形束流碰撞，在每束 1 GeV 下实现 2 x 10^<32>cm^<-2>s^<-1> 的最大光度和正电子。 1.4和2.0 cms能量之间正负电子碰撞产生强子的数据相对较少；如果这个 VEPP-2000 能够达到其设计光度，使用 VEPP-2000 进行的实验将能够理解基本过程，并为高能物理的进步做出很大贡献。由于其对称性，圆束碰撞本质上是在一维的，可以预见，这一一维特征使得束-束碰撞时的非线性效应显着减弱。 BINP-KEK 合作完成的计算机模拟确实表明，VEPP-2000 机器通过对其操作点进行仔细和微调，将达到其亮度目标。由于容纳 VEPP-2000 的可用面积有限，磁铁应具有高磁场。特别是，该机器需要两对13特斯拉超导螺线管磁体，这是制造圆梁所必需的。VEPP-2000的建造已于2007年春季完成，并已开始调试。几年后它将产生许多物理成果。
