Helium-Filled Flight Path

One of the core research and development projects of the NE-CAT is low-resolution crystallography.  Design and construction of a helium cone to reduce air absorption of Bragg diffraction spots is one of the goals of this core.  A preliminary design of the cone was made and constructed in August 2014. This was used by Wayne Hendrickson group to collect highly redundant data from multiple crystals to use in S-SAD experiments.
