Sample environment plays a crucial role for most beamline-based experiments. The main task of our department is the control of the physical parameters at the sample position like temperature, magnetic or electric field or pressure. In addition, we offer solutions for in-situ and in operando photon studies i.e. of gas absorption properties, catalytic processes, (electro-) chemical reactions in batteries and fuel cells, etc.
The sample environment group supports all beam line experiments at BESSY-II as well as the HZB inhouse labs. We provide our experience and a repertoire of sample environment equipment and tools to the beamlines and users groups. We help with the development and construction of novel sample environment components, which can be firmly integrated in the experimental stations or operated as modular and variable sample environment in combination with direct user service.
Tasks and Services
Design and Consulting
We support beamlines and HZB-labs with the design, construction, commissioning, or improvement of dedicated sample environment devices, i.e. near ambient pressure modules, special cryostats, magnets, sample holders, flow-through cells, liquid jets, ...
Cryogenic Support and Infrastructure
Our technical support is complemented by providing cryogenic tools and infrastructures related to the operation of sample environment, e.g. automatic cryoliquid refilling system, liquid helium management, ...
In collaboration with the Institute Quantum Phenomena in Novel Materials (EM-IQM) and the Institute Electrochemical Storage (EM-IEES) we offer complementary labs for sample characterization measurements and sample preparation issues.
Recent examples where sample environment has a essential impact on the feasibility and results of the investigation:
- Discovery and understanding of the negative gas adsorption effect in metal–organic frameworks (MOFs)
- Prove of magnetic monopoles in the Spin Ice Dy2Ti2O7
