Abstract:
In a beam filter assembly, a base filter is employed to modify a beam quality of a radiation beam of a base energy level and a first filter slice is stacked with the base filter to modify a beam quality of a radiation beam of a first energy level higher than the base energy level. In a beam filter positioning device, a base stage carries a base filter and a first stage carries a filter slice. The base stage is provided with a first engagement site and a second engagement site. The first stage is provided with a first engagement site, a second engagement site, and an open port. The first stage and the base stage are each independently movable relative to the beamline. The first stage is engageable with the base stage when at least one of the first and second engagement sites of the first stage is aligned with at least one of the first and second engagement sites of the base stage, and is further movable with the base stage in unison when engaged.

Claim (Index 45):
The beam filter positioning device of  claim 44 , wherein the first stage, the second stage, and the base stage each further carries a scattering foil, and the first stage, the second stage, and the base stage are arranged such that\n when the second engagement sites of the first and second stages are aligned with the first engagement site of the base stage, the first and second stages are engageable and further movable with the base stage in unison to position the scattering foil carried by the base stage in the beamline; or when the first engagement site of the first stage is aligned with the second engagement sites of the second stage and base stage, and the first stage is engageable and further movable with the second stage and the base stage in unison to position the scattering foil carried by the first stage in the beamline, or when the first engagement site of the second stage is aligned with the second engagement sites of the first stage and base stage, and the second stage is engageable and further movable with the first stage and the base stage in unison to position the scattering foil carried by the second stage in the beamline.
