High-Resolution RBS (HIRRBS)

The Albany high-resolution magnetic spectrometer facility is Phase I operational. It provides RBS and nuclear reaction analysis with an energy resolution of about 3 times better than is available with a conventional detector.

Call for samples: The high-resolution of this facility translates into better mass and depth resolution in RBS or other methods of ion beam analysis. A sample application is given briefly below. The purpose of this notice is to encourage SRC member companies with analytical problems that would benefit from high-resolution ion beam analysis to contact HIRRBS. This facility was partially funded by SRC and its future funding depends on demonstrating utility to member companies.
