摘要

上海光源（SSRF）直线加速器正常运行时

重复频率2 Hz

单束团脉宽1 ns

电荷量1 nC。近年来

国际同步辐射领域发展起来的恒流注入模式要求直线加速器以弱流强运行

在相同的重复频率和脉宽下

单脉冲电荷量越小越好

此方法重复性较好。本文在理论计算基础上

结合实验

给出了弱流强稳定运行的实现方法

确定了在Top-up模式下

直线加速器的脉冲电荷量为0.1 nC。

Abstract

According to design of the SSRF linac

it is operated at 1 nC of beam current

2 Hz of repetition rate and 1 ns of pulse width.Nowadays

more and more synchrotron radiation facilities are operated in Top-up mode which requests the linac to work at weak beam current.This implies that in the same repetition rate and pulse width

the current shall be as weak as possible.In this paper

we report our efforts for running the SSRF linac at weak beam current.After theoretical calculation and experiments for weak beam current operation of the linac it is operated at 0.1 nC of current in Top-up mode.
