The new generation of hadron machines may profitably take advantage of channeling for steering and collimation of high-energy particle beams. In that case, the requirements on the quality of the crystal surface are rather stringent in terms of both lattice perfection and roughness. A new method to achieve an optimal quality of the surface is here presented. Structural and morphological characterizations show that it fulfils all needed specifications for application in hadron machines.

Abstract
The new generation of hadron machines may profitably take advantage of channeling for steering and collimation of high-energy particle beams. In that case, the requirements on the quality of the crystal surface are rather stringent in terms of both lattice perfection and roughness. A new method to achieve an optimal quality of the surface is here presented. Structural and morphological characterizations show that it fulfils all needed specifications for application in hadron machines.File in questo prodotto:
