Abstract

The energy spread of the VEPP-4M electron–positron collider at the Budker Institute of Nuclear Physics was measured in the 1100–4750 MeV range (i.e., in the entire operating energy range of the collider) in two ways: based on the beam length and based on the envelope of betatron oscillations. The influence of the Touschek effect on this parameter was studied in the 1–1.5 GeV range. The results obtained using the two different methods agree well.

整个能量范围内VEPP-4M对撞机能量散布的测量

摘要

Budker核物理研究所的VEPP-4M电子-正负对撞机的能量扩散是通过两种方式在1100-4750 MeV范围内（即在对撞机的整个工作能量范围内）测量的：并以电子感应加速器的包络为基础。在1–1.5 GeV范围内研究了Touschek效应对该参数的影响。使用两种不同方法获得的结果非常吻合。
