Abstract:
A degrader for use in the field of the application of a particle beam has excellent degrading capabilities and, for the same energy loss in the degrader, a lower emittance increase than currently used materials, without generating a strong neutron flux and without having severe toxic characteristics. The degrader includes degrading active material composed of Boron Carbide B 4 C. The degrader has an amount of multiple scattering that is lower than for graphite for the same energy loss. The use of B 4 C increases the transmission by typically 35% for the beam degradation to low energies, which is a significant and useful amount of beam intensity increase in particle therapy. The B 4 C material does not become more radioactive than graphite, so that there will be no additional problems at service activities. Further, B 4 C when used as a degrading active material does not have severe toxic properties.

Claim (Index 3):
The degrader according to  claim 1 , wherein said degrading active material is assembled as one element or block.
