Abstract

The VEPP-5 injection complex, consisting of two linacs and a damping storage ring, delivers electron and positron beams to the VEPP-4M and VEPP-2000 colliders operating at BINP. Over three years of injector operation, its efficiency has significantly increased and the maximum positron-storage rate has reached 1.2 × 10¹⁰ s^–1. This progress was reached through tuning the constituent machines, upgrading the accelerator technology, and deploying a new 11-MHz station of RF cavities. By the start of the next running season, a new electron gun with a significantly increased maximum current and cathode lifetime will be installed.

VEPP-5注射复合体的现状和计划升级

摘要

VEPP-5注射复合体由两个直线加速器和一个阻尼存储环组成，将电子束和正电子束传递给在BINP运行的VEPP-4M和VEPP-2000对撞机。经过三年的喷射器运行，其效率已大大提高，最大正电子存储速率已达到1.2×10 ¹⁰ s ^–1。通过调整组成机器，升级加速器技术并部署新的11 MHz RF腔站，可以实现这一进展。在下一个运行季节开始之前，将安装新的电子枪，该电子枪的最大电流和阴极寿命将大大增加。
