Title: NIST Demountable Cells for Neutron Scattering Experiments
NIST has developed demountable titanium cells that are widely used as sample holders in neutron scattering experiments at the NCNR SANS facility. These cells are designed for easy assembly, disassembly, and cleaning, making them suitable for various sample types such as gel, melt, powder, and liquids. The cells come in fixed sample thicknesses of 1 mm, 2 mm, and 4 mm, with special “0 mm” path length cells available for use with spacers or solid samples to define the sample thickness.
The 1 mm path length cells require a sample volume of 0.5 ml, and the volume scales proportionally with the sample thickness. Samples are held in place by two quartz windows, which are sealed using an o-ring system. Retaining rings compress the o-rings and are secured by four screws, which can be inserted and removed using electric, torque-locking screw drivers. Liquid samples can be added through the top using a syringe, and different materials are available for the o-rings to ensure compatibility with various solvents. PDF and zipped STEP files are provided for all cell bodies and retainer rings.
