  The SwissFEL light-facility will provide coherent X-rays in the wavelength
region 7-0.7 nm and 0.7-0.1 nm. In SwissFEL, view-screens and wire-scanners
will be used to monitor the transverse profile of a 200/10pC electron beam with
a normalized emittance of 0.4/0.2 mm.mrad and a final energy of 5.8 GeV.
Compared to view screens, wire-scanners offer a quasi-non-destructive
monitoring of the beam transverse profile without suffering from possible
micro-bunching of the electron beam. The main aspects of the design, laboratory
characterization and beam-test of the SwissFEL wire-scanner prototype will be
discussed.
