Abstract

VEPP-2000 is the only electron–positron collider with round beams. This factor enables one to increase the beam–beam effect limit. During the 2018–2019 season, the experimental program was focused on the energy range of 550–990 MeV per beam. Data accumulation was performed using CMD-3 and SND detectors. The measured luminosity integral proved to have a record value of 68 pb^–1 per detector. After connecting to the BINP injection complex in 2016, the luminosity of VEPP-2000 is limited by the beam–beam effects in the entire energy range.

Vepp-2000 BINP电子-正电子对撞机的状态

摘要

VEPP-2000是唯一具有圆形束的电子-电子对撞机。这一因素使人们能够增加束流效应极限。在2018–2019赛季，该实验计划的重点是每束550–990 MeV的能量范围。使用CMD-3和SND检测器进行数据累积。每个探测器的实测光度积分记录值为68 pb ^–1。在2016年连接到BINP注入复合体后，VEPP-2000的光度受到整个能量范围内光束的影响。
