More Highlights...
Neutron Techniques
Crystallography The diffraction of neutrons from a crystalline sample
furnishes information about the structural arrangement of the atoms
that compose it.
Reflectometry   probes the nanoscale structure of surfaces and interfaces
Small Angle Neutron Scattering    is a powerful method for characterizing the nanoscale structure of solids, liquids, plastics, and macromolecules.
Spectroscopy  The energy scale of neutrons ( meV ) makes them ideal probes of the dynamics of materials.
Chemical Analysis  Several nuclear methods are used at the NCNR, including prompt-gamma neutron activation analysis, instrumental neutron activation analysis, and cold-neutron depth profiling
Other Methods  Neutron interferometry, neutron radiography, and fundamental physics using neutrons are active research areas at the NCNR
The Center For High Resolution Neutron Scattering (CHRNS), supported by the National Science Foundation and NIST, is an important component of the NCNR, providing users with access to six neutron scattering instruments.

Cold Neutrons for Biology and Technology (CNBT) is a bioengineering research partnership funded by the National Insitutes of Health. The CNBT operates the AND/R reflectometer to investigate the structure of membranes.

NCNR Seminar Schedule

The operating cycle that was scheduled for Aug. 20 - Sept. 27 will not be run. Instead, previously planned maintenance work will begin immediately, and we anticipate that the next operating cycle will start in November 2004. Also note that the next proposal deadline has been moved up by one week. It is now September 23, rather than the previously posted date of September 30.


The next proposal deadline is September 23, 2004.
Detailed information ....

We have posted some proposal statistics summarizing the last two proposal rounds.


Examine data from a survey conducted by the NCNR Users' Group.
