SoTeXS

The SoTeXS (Soft-to-tender X-ray spectroscopy) beamline will extend and complete the HZB portfolio for battery research, including energy storage, the required sustainability in mobility and transport demand, and novel battery concepts. The use of abundant, environment-friendly materials, detailed insights into operating electrochemical cells, and an understanding of degradation processes will lead to new, sustainable, and more efficient materials for energy storage. In particular, a combination of the soft and tender X-ray regime (500 eV – 5000 eV) will allow us to investigate almost all elements relevant to battery applications and their behavior with operando measurements.


Project Organization

The development of the SoTeXS beamline involves higher complexity than a standard beamline at BESSY II. This project requires the collaboration of multiple specialized teams, which calls for careful planning and coordination. Each team brings its unique expertise to ensure the beamline is functional and meets advanced scientific standards. Our project is organized into five work packages, each designed to focus on different aspects of the project. This structure helps manage the interactions among various teams effectively and supports the smooth progress and timely completion of the project.


WP1: Undulator
WP1 focuses on the development and integration of a state-of-the-art cryocooled in-vacuum undulator. The work includes coordinating with external partners for the fabrication of the undulator and ensuring it meets the specific scientific requirements of SoTeXS.

  • Work Package Leader: Atoosa Meseck

WP2: Beamline
WP2 is dedicated to designing and constructing the beamline infrastructure. A primary challenge is the development of a multilayer coated monochromator able to cover the soft to tender X-ray energy range between 500 eV and 5000 eV.

  • Work Package Leader: Andrey Sokolov

WP3: Sample Environment
WP3 will develop a specialized 'battery hotel' where batteries can be stored for up to one year, and measured on request. The battery exchange with the endstation will be automated.

  • Work Package Leader: Klaus Kiefer

WP4: Endstation
WP4 is responsible for developing sophisticated endstations equipped with advanced detectors and instrumentation.

  • Work Package Leader: Sebastian Risse

WP5: Software
WP5 will develop robust control systems and data acquisition software, leveraging the core expertise of the group in EPICS and Bluesky.

  • Work Package Leader: William Smith
