Summary
New furnace and cryogenic systems expand non-ambient powder diffraction capabilities from 10-1500 K. This advancement enhances materials research at the Synchrotron Radiation Source, Daresbury Laboratory.
Area of Science:
- Materials Science
- Crystallography
- Synchrotron Radiation
Background:
- Non-ambient powder diffraction requires specialized temperature control equipment.
- Existing facilities at the Synchrotron Radiation Source, Daresbury Laboratory, needed enhancement for wider temperature ranges.
Purpose of the Study:
- To describe the commissioning of new high-temperature furnace and cryogenic systems.
- To extend the temperature range for powder diffraction experiments.
Main Methods:
- Assembly of an induction heater coil furnace and a closed-cycle refrigeration cryogenic system.
- Integration of these systems with the high-resolution powder diffractometer (Station 2.3).
Main Results:
- Successful commissioning of both high-temperature (up to 1500 K) and low-temperature (down to 10 K) capabilities.
- Demonstration of apparatus operation using iron (Fe) and ammonium bromide (NH4Br) powder samples.
Conclusions:
- The new furnace and cryostat significantly enhance non-ambient powder diffraction capabilities.
- The developed apparatus is versatile and applicable to various diffraction experiments and geometries.
