Small-Angle Neutron Scattering (SANS) Instrument

   

The Time-of-Flight Small Angle Neutron Scattering (ToF SANS) instrument is being built at reactor source, at ANSTO, Australia. SANS is complex machine. One of key parts of it is large detector vessel. ADC has taken the overall concept for the vessel developed by ANSTO designers, and provided final engineering design and then built the detector vessel as imaged below. This consists of a very large vacuum vessel with an internal track for accurately moving a detector up to 18.8 meters. In addition the entire vessel can be accurately moved 1.5 meters using external rails and a ball screw. The front end consists of a sample window and 630 mm gate valve. The rear of the vessel has a hatch with an articulated hinge. There is a central man-way hatch on the top and 17 ports for vacuum pumps, electrical, feed throughs, and sensors. The vessel was designed in compliance with ASME BPVC, Section VIII, Division 1, 2011 Revision, with exceptions for good vacuum practice and approved by the Australian Work Cover Authority.
