Sample Environments

In the following an overview of sample environments either provided by the beamline P02.1, by the PETRAIII sample environment group or by collaborative users is given. Please be aware that you have to communicate to your beamline local contact well in advance, which sample environment you want to use. For setups available on a collaborative basis, please contact responsible persons before the submittance of your proposal!

Beamline and Infrastructure setups

Oxford Hot-Air Blower

The Oxford Hot-Air-Blower heats up a compressed air stream in order to transfer heat to a sample. It is mostly used with our capillary setup with spinning option, where it sits beneath the capillary. The temperature range is from room temperature (293 K) up to 1200 K.

Please be aware, that you have to make calibration measurements by yourself within your requested beamtime, since the temperature highly depends on the actual working distance.

Mini Hot-Air Blower

The Mini Hot-Air-Blower (longer and smaller nozzle than for the Oxford Hot-Air-Blower) heats up a compressed air stream in order to transfer heat to a sample. It is mostly used with our capillary setup with spinning option, where it sits beneath the capillary. The temperature range is from room temperature (293 K) up to 900 K.

Please be aware, that you have to make calibration measurements by yourself within your requested beamtime, since the temperature highly depends on the actual working distance.

Ceramic Heater

The ceramic heater is our custom-build device in order to achieve temperatures between room temperature (293 K) up to 1200 K for long-term heating experiments, where no spinning of the capillary is required. It can also be equipped with other types of samples like metal rods, as long as they have no bigger diameter than 1 mm. Since the device can be immediatley powered off, quenching procedures by environmental cooling are possible.

Please be aware, that you have to make calibration measurements by yourself within your requested beamtime, since the calibration highly depends on the actual setup.

Ceramic heater

Linkam Furnace/Cooler

The Linkam Furnace/Cryostat can operate in a wide temperature range of 77 K up to 823 K with high precision of ±1 K. The possible heating rates are between 1 and 20 K/min. It can be loaded with a capillary or with a metal rod with diameters of up to 0.9 mm and has no spinning capability.

Please be aware, that you have to make calibration measurements by yourself within your requested beamtime, since the temperature highly depends on the actual setup.

Oxford Cryostream

The Oxford Cryostreamer Cooler is a blower systems which works with liquid nitrogen and can therefore achieve temperatures from 500 K down to 80 K. It is mostly used with our capillary setup with spinning option, where it blows axial towards the capillary in order to cool or the heat the capillary uniformly with a laminar flow.

Please be aware, that you have to make calibration measurements by yourself within your requested beamtime, since the temperature highly depends on the actual working distance.

He Cryostat with Cold-Finger

The available He-Cryostat with cold finger can be used for performing PXRD experiments (no total scattering experiments possible!) in a temperature range form 300 K down to 5 K. Above 10K, the temperature precision is ±1 K. The cold fingers offers the possibilities to mount 5 capillary samples at once, without any spinning capability.

Please be aware, that you have to make calibration measurements by yourself within your requested beamtime, since the temperature highly depends on the actual setup.

He Flow-Cryostat

The He Flow-Cryostat is currently under commissioning and not publicly available!

The He-Flow-Cryostat has a large window and therefore it is suited to make total scattering measurements of capillary samples at low temperatures. The temperature range is from room temperature (293 K ) down to ??? K. The capillaries are mounted without any spinning capability.

Please be aware, that you have to make calibration measurements by yourself within your requested beamtime, since the temperature highly depends on the actual setup.

Kammrath & Weiss Stress Rig

The Kammrath & Weiss Stress rig can be used to apply stress on dog-bone shaped standard samples (see also https://www.kammrath-weiss.com/en/products/materials/tensile-compression.html) with applied forces of 500 N up to 5 kN. It can work in tensile or compressive mode with elongation rates of 0.2-20 µm/s (micrometer/second). The possible elongation range is 20-60 mm. Furthermore a heating system is available with a temperature range from room temperature (293 K) up to 673 K. If required a protective gas atomsphere can be applied (e.g. Argon atmosphere).

Capillary Spinner for Gas Experiments

The capillary spinner for gas experiments is a custom-made spinner device which allows for rotating a gas filled capillary mounted on a commercial Huber goniometer head by 360° forth and back. This setup can be used only for non-corrosive gases!

Biologic VMP3 Potentiostat

Biologic VMP3 potentiostat

The Biologic VMP3 potentiostat offers 8 channels (1 channel is equipped for impedance spectroscopy) in order to control for example charging and discharging of sample (e.g. batteries). It is controlled by the EC lab software.

This device can also be borrowed from the P02.1 beamline in order to perform experiments at other DESY facilities. However, if you use this potentiostat at another beamline/experiment besides at the P02.1 beamline, you HAVE TO acknowledge the use of the potentiostat in any kind of publication by mentioning it in the acknowledgement with "This work was performed by using the Biologic potentiostat of PETRAIII beamline P02.1."

 

Collaborative setups

HZG High Pressure Gas Cell

The HZG high pressure gas cell was especially designed for performing powder experiments under high gas pressures up to several hundred bar. Powders are usually loaded into sapphire capillaries and can then also be heated with a heater placed below the capillary. In addition to static high pressure experiments, the cell can also be used in a flow mode.

This device is only available on a collaborative basis together with the Helmholtz-Zentrum Geesthacht. For further information, please contact Dr. Martin Etter (martin.etter@desy.de) in advance before you submit proposals!

Retsch Ball Mill

Mechanochemical experiments can be performed at the beamline using a modified Retsch MM400 shaking ball mill. Reactants have to be put in special plastic jars together with steel or tungsten carbide balls and can then be milled at a maximum frequency of 30 Hz for a maximum time of 90 min.

This device is only available on a collaborative basis together with the Max Planck Institute for Solid State Research, Stuttgart. Please contact Dr. Martin Etter (martin.etter@desy.de) in advance.
