VSANS Instrument for NIST (Very Small Angle Neutron Scattering)
ADC is designing and building a large instrument for National Institute of Standards And Technology (NIST). This instrument is similar to a more complex instrument we designed and delivered to Ansto in Australia called the Bilby SANS instrument.
The NIST VSANS and the Ansto Bilby SANS instruments have very similar dimensions for length and diameter and have similar requirements for internal detector motion, top access port, walkway supports, and ports; however, the Bilby SANS instrument was more complex because the vacuum requirement was lower (7.5x10-5 Torr) and the entire (60,000 pound) vessel was required to move 1.5 meters on external rails with a repeatability of 100 um, which ADC achieved.
A brief comparison of specifications is provided below.
