Laboratory-based X-ray spectrometer for actinide science.

Area of Science:

• Radiochemistry
• Materials Science
• Nuclear Engineering

Background:

• X-ray absorption and emission spectroscopies are crucial for actinide research, revealing subtle structural and electronic property changes.
• Synchrotron-based experiments are standard but involve high costs and logistical challenges for radioactive sample transport.
• Advancements in laboratory-based X-ray spectrometers offer viable alternatives for actinide characterization.

Purpose of the Study:

• To report the construction and implementation of a laboratory-based X-ray spectrometer (LomonosovXAS) for actinide research.
• To demonstrate the utility of laboratory spectrometers as cost-effective and accessible tools.
• To showcase the application of the developed spectrometer in relevant actinide systems.

Main Methods:

• Development and implementation of a Johann-geometry X-ray spectrometer (LomonosovXAS).
• Utilizing X-ray absorption and emission spectroscopies for elemental analysis.
• Application to actinide systems, f-element chemistry, nuclear power engineering, and spent nuclear fuel disposal.

Main Results:

• The LomonosovXAS spectrometer was successfully constructed and implemented in a radiochemistry laboratory.
• Laboratory-based spectroscopy provides data comparable to synchrotron results.
• The instrument is effective for studying actinide systems relevant to nuclear power and waste management.

Conclusions:

• Laboratory X-ray spectrometers are effective, reliable, and accessible alternatives to synchrotrons for actinide research.
