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.
