The instruments of the Large Scale Structures (LSS) group of the Institut Laue Langevin are all dedicated to measuring structures on the scale of 1 to several 100 of nanometers.  A vast range of science is covered:  from magnetism to polymers and colloids to biological structure, in solution, in the solid state or in very thin films.

Information on these large scales is obtained by measuring at especially low Q, exploiting neutrons from each of the ILL reactor's cold sources.  Although the instruments all exploit cold neutrons they fall naturally into three classes:  small-angle scattering instruments, diffractometers and reflectometers.

First-time users of the ILL are encouraged to contact one of the group scientists having a similar field of interest before submitting a proposal for use of one of the group instruments.

The group operates 7 instruments availiable to users as well as one CRG instrument that contribute 30% of their time to outside users.

The LSS group also has the responsibility for running the Chemistry and Soft Matter Laboratories located on the second floor of ILL20, as well as the ILL/EMBL Deuteration Facility located in the Carl-Ivar Brändén Building (CIBB).  Further equipment is availiable from the ESRF Chemical Laboratories though an ILL/ESRF agreement.  More extensive biochemical facilieis are availaible in the EMBL labs on the lower floors of ILL20.
