In-situ Shear Cell

 

The RheoSANS  is based on the Anton-Paar MCR 500 model rheometer modified for in-situ SANS measurements. It is controlled by Anton Paar RheoPlus software where SANS data may be acquired under different conditions at the same time rheometric tests are conducted.  Temperature is logged at the sample position.  The beam on the sample is defined by a slit package which balances flux and counting time with restrictions of the measurement geometry. 

 

 

The measurement system consists of two concentric quartz cylinders separated by a gap.  A sample is placed in the gap between the two cylinders.  The outer cylinder is static covered by temperature jacket which does not interfere with access to the cell by the neutron beam or the scattering path. The inner cylinder is rotated and is the rheogology sensor.  SANS data may be acquired in direction tangential to the flow, or in a direction normal.
