Small Angle Scattering Instrument
V4 allows for the measurement of density composition and magnetization fluctuations in materials on a length scale from 0.5 nm to 400 nm. At short distance the 2D-detector can be moved vertically by 0.17 m, extending the Q range to even higher values. A large sample chamber is connected to the vacuum system with the detector and collimator tubes. Automatic sample changers (both T and B controlled) are available.
A high transmission supermirror polarizer can be introduced by remote control in front of the 12 m collimation without any modification of the instrument alignement. The polarization direction can be reversed by a RF gradient spin-flipper in front of the sample. The SANSPOL option is characterized by a high neutron flux of more than 30% of the non-polarized beam (wavelength dependent), a high degree of polarisation ( > 90%) and high efficiency of the spin-flipper ( > 95%) for λ< 1.8 nm without any additional background.
Using the list mode data acquisition time-stamped measurements can be performed. Stroboscopic measurements by using a trigger signal allow to investigate the kinetics of periodic processes. The chopper system based on TISANE technique allows for studies of microsecond dynamics.
