The small-angle neutron scattering instrument (SANS) of CSNS is a very important neutron technique useful for probing structures from around 1 nanometre to more than 100 nanometres. It has a wide range of applications from studies of polymers to nanoparticles.
SANS is the first pulsed-source general-purpose time-of-flight SANS instrument in China. It utilizes beam port #1 of the CSNS target station facing a coupled liquid hydrogen moderator and adopts a short straight beamline configuration with the classic point-focusing pin-hole camera geometry. Compared with the curved neutron guide configuration, this design can obtain a better neutron transmission at short wavelength and enable a wide Q range during experimental measurements.
1. Reliable SANS data between 0.01~0.5 -1
2. Instrument resolution better than ~30% around Qmin3. Good dynamic range, sample space4. Variable sample size
