What
makes a good detector?
The following section introduces
some of the most important issues that can be used to evaluate the ability
of an X-ray detector to accurately and efficiently detect X-rays.
Manganese
resolution, MnKα FWHM
Resolution is quoted as the width
of the peak at half its maximum height (FWHM). The lower the number the
better the resolution a detector has and the better it will be at resolving
peaks due to closely spaced X-ray lines
Manganese resolution is measured
by placing a piece of pure manganese under the electron beam. On a
microscope the resolution is often quoted at 1000cps. This count rate is
much lower than is used in practice for most microanalysis experiments. It
is important to determine whether this resolution is maintained at more
realistic and productive count rates.
