Y-12 National Security Complex

Contact Y12 About This Technology

Technology Marketing Summary

The Reactor Cell Assembly allows environmental monitoring of air-sensitive, solid-gas, and thermal decomposition reactions. The aluminum chamber has one or more viewports, a heated sample stage, and gas inlet parts. Each face of the cube has an opening in which various configurations allow a researcher to conduct various spectroscopic or microscopy applications. Gas-solid reactions, component compatibiliy, and outgassing studies cna be conducted in a controlled environment.  

  • Solid block aluminum construction
  • Openings for eyepiece, light source, specimen, and/or inlet and outlet gas or vacuum attachments
  • Windows may be constructed from quartz, sapphire, or zinc selenide
  • Reaction chamber contains a heater as well as gas inlet ports
  • Compact
  • Modular construction
  • Variable temperature (hot and cold)
  • Vacuum and pressurized operation
  • Superior resolution
  • Can be used in a wide range of optical and laser spectroscopy applications, as well as optical microscopy applications
  • Highly configurable
  • Aluminum design prevents ougassing of hydrogen and protects air-sensitive material from the outside environment
Applications and Industries
  • In situ vibrational analysis of reactions (thermal decomposition, corrosive environments, compatability)
  • Study of hydrogen outgassing
  • Simultaneous microscopy or vibrational spectroscopy and gas analysis
More Information

TRL 9: The spectroscopic reaction chamber has been fabricated by Accurate Machining and Design in Oak Ridge and requires little validation beyond initial use and testing.

Inventors: Quirinus Grindstaff, Ashley Clinton Stowe, Norm Smyrl, Louis Powell, and Sam McLane

Reactor cell assembly for use in spectroscopy and microscopy applications
The present disclosure provides a reactor cell assembly that utilizes a novel design and that is wholly or partially manufactured from Aluminum, such that reactions involving Hydrogen, for example, including solid-gas reactions and thermal decomposition reactions, are not affected by any degree of Hydrogen outgassing. This reactor cell assembly can be utilized in a wide range of optical and laser spectroscopy applications, as well as optical microscopy applications, including high-temperature and high-pressure applications. The result is that the elucidation of the role of Hydrogen in the reactions studied can be achieved. Various window assemblies can be utilized, such that high temperatures and high pressures can be accommodated and the signals obtained can be optimized.
