Measurement of beam intensity profiles versus transverse coordinates.

The intensity profile is measured by a wire which rotates inside the vacuum of a beam transport line. The wire detects particles directly or by measurement of the charge released by secondary electrons. The scan system itself is mounted to a CF-150 flange and can be attached directly to a standard diagnostic chamber The scanning wire is moved into a position which will not disturb the beam if scanner is not activated. The wire is driven from both ends to avoid deformation due to the heating of the wire by impinging particles.
