7.Enhanced Sensitivity for Superlight ElementsThe layered structure analyzer (LSA), which uses curved crystals for convergence, provides almost ten times highersensitivity for X-rays than conventional detectors.Unlike the conventional dispersing crystals, the LSA has synthetic multilayer structures.The spacer is made of the material and has the thickness that gives the best lattice constant to sense X-rayintensities at the highest sensitivity for such elements as Be, B, C, N, O, F, Na, and Mg.TAP.
