2013 R&D 100 Winner
Univ. of Manchester NanoBPMThe excellence of brilliant x-ray beams produced by the latest generation of synchrotron radiation facilities is undermined by the difficulty of keeping intense x-ray beams co-located with samples to sufficient precision. Long optical paths and widely spaced reflective elements mean that small relative displacements will cause large displacements and defocusing. With the introduction of the NanoBPM, scientists at Univ. of Manchester and FMB Oxford Ltd. have invented a diagnostics method for intense, highly collimated x-ray or particle beams that allows a non-destructive method of characterizing the beam in full detail, without placing a detector into the beam where it would suffer from radiation damage.

The in situ, or transparent, system uses an off-axis coded aperture camera that provides a magnified image of the beam cross-section, enabling beam positioning with high precision. The new method magnifies any motions of the beam position, allowing highly precise beam position measurements. Unique geometry and lensless imaging using coded apertures provide a simple way of magnifying beam movements by a factor of up to 30 times, resulting in sub-micrometer precision of beam position measurement.
