An X-ray imaging system that produces one or more fan-shaped beams is described. The semiconductor device includes a substrate, a memory device, and a select transistor. A whisle is housed in the whistle housing reservoir by insertion into one of the mounting tubes. The charged constituents of the plume are influenced by the magnetic fields and are thus deflected to the substrate, while the larger atomic clusters and particulates are advantageously not deflected. The transmitted beam is spectrally modified by the filter, and couples into the output collimating assembly.
