ABSTRACT:
Apparatus for X-ray excitation of a sample, including a substantially stationary X-ray source and X-ray optics, including at least one secondary target and a movable element. The movable element has at least a first position wherein X-rays emitted by the source excite the sample directly, and a second position wherein X-rays emitted by the source strike the at least one secondary target, causing the secondary target to emit X-rays that excite the sample, while the X-rays emitted by the source are substantially prevented from exciting the sample.
