Purchase of a brand-new high-field cryostat for Mössbauer spectroscopy

Purchase of a brand-new high-field cryostat for Mössbauer spectroscopy with the following features:

- Cooling with closed helium circuit ("cryogen-free")

- "Split-pair" magnet system for measurements with the ?-beam parallel and perpendicular to the magnetic field

- Maximum field of 5 T for measurements in the temperature range of 4.2 - 200 K

- Sample change through "top-loading"

- Stray field at a distance of 200 mm from the sample <60 mT at full field

- "Reentrant bore tubes in the two horizontal beam paths for positioning the Mössbauer source in the zero field of the magnet close to the sample.

- Aluminized mylar foil as window material for the ?-beam

- Maximum line width in the Mössbauer spectrum of 0.32 mms-1 by dampening the vibrations caused by the chiller

- Electrical connection via three-phase 3 phases; Cooling water requirement maximum 6-9 l/min

incl. delivery free of charge at the place of use, installation, commissioning, instruction
