摘要

能源材料光束线站是上海光源首条软、硬X射线相结合的合支光束线站，两个插入件光源采用Canted模式，光束夹角仅为2 mrad。前端内放置偏转镜箱，软线经过偏转镜后光束偏转2.4°，软、硬线交叉之后分开。该前端要承担高达7.81 kW的热负载，而且在前端内部两条光束共用设备。为了实现实验站对两条光束的独立控制，前端的设备结构与一般插入件前端设备不同，需要采用全新的结构，与其它只有一个通光孔径的插入件前端关键设备相比，此前端关键设备设计有两个通光孔径。目前，该前端已经安装完成，并且结构和布局完全满足光束线站的技术要求。

Abstract

Background

The current beam lines structure design cannot satisfy the requirement of the first combined beamline station with soft and hard X-rays in Shanghai synchrotron radiation facility (SSRF).

Purpose

This study aims to design the super-small angle Canted front-end at SSRF to support a wide-energy-range experimental platform with multiple methods for energy material research.

Methods

Two undulators

elliptical polarization undulator (EPU) and in vacuum undulator (IVU)

were employed in the wide-range energy material beamline (E-Line) that contains soft and hard X-rays located in the straight line with a Canted angle of 2 mrad. The separated plane mirror

SM1

was designed to be located at the front-end. After SM1

the soft line was deflected 2.4°

allowing two dedicated beam lines to be set.

Results

The two beam lines share the front-end components

and can independently operate the components of the front-end. The front-end of E-Line adopt a new structure and layout different from the standard ones that can handle the heat load up to 7.81 kW. Compared with the key equipment of other common insert device front-end with only one through-light aperture

the one of this front-end was designed with two through-light apertures.

Conclusion

The installation of E-Line front-end has been accomplished

and the structure and layout fully satisfy the technical requirements of the beamline.
