A novel study on a different use of polycapillary optics is presented. The scope of this study is to achieve an efficient radiation collimation due to handled beam profiling that avoids the typical one based on total external reflection into the capillary channel. For this purpose a vibration is applied to a monocapillary in order to emulate a ‘‘virtual roughness’’ on the channel internal wall surface. The transmission properties of such a system for different vibrational states are discussed.

Abstract
A novel study on a different use of polycapillary optics is presented. The scope of this study is to achieve an efficient radiation collimation due to handled beam profiling that avoids the typical one based on total external reflection into the capillary channel. For this purpose a vibration is applied to a monocapillary in order to emulate a ‘‘virtual roughness’’ on the channel internal wall surface. The transmission properties of such a system for different vibrational states are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
