The investigation of beam halo transverse distributions is important for theunderstanding of beam losses and the control of backgrounds in Future LinearColliders (FLC). A novel in vacuum diamond sensor (DSv) scanner with fourstrips has been designed and developed for the investigation of the beam halotransverse distributions and also for the diagnostics of Compton recoilelectrons after the interaction point (IP) of ATF2, a low energy (1.3 GeV)prototype of the final focus system for the ILC and CLIC linear colliderprojects. Using the DSv, a dynamic range of $\sim10^6$ has been successfullydemonstrated and confirmed for the first time by simultaneous beam core($\sim10^9$ electrons) and beam halo ($\sim10^3$ electrons) measurements atATF2. This report presents the characterization, performance studies and testsof the diamond sensors using an $\alpha$ source as well as using the electronbeams at PHIL, a low energy ($< 10$ MeV) photo-injector at LAL, and at ATF2.First beam halo measurement results using the DSv at ATF2 with different beamintensities and vacuum levels are also presented. Such measurements not onlyallow one to evaluate the different sources of beam halo generation but also todefine the requirements for a suitable collimation system to be installed atATF2, as well as to optimize its performance during future operation.
