ADVENT DIAMOND, INC. — Department of Energy SBIR Phase II: 13a

Description

This proposal is to develop a technology to address DoE’s need for transparent x- ray detectors for synchrotron beamlines facilities. The increasing number of users with different beam energy, flux, shape and size requirements mean that the beam needs adjustments between each use. Conventional beam monitoring technology based on toroidal mirrors is time consuming and reduces the user time and increases the lead time between experiments. Advent Diamond will solve problem with the advancement of transparent x-ray monitor that includes – diamond x-ray detectors with transparency of >90% for 5 keV beam and pixel size less than 50 m; compatible compact and advanced readout with the ability to measure wide range of 107 photons/s to 1016 photons/sec per pixels; and live data readout software. The proposed in-beam transparent (>90% for >5keV) x-ray beam monitor will allow users to measure beam intensity, position, and spatial distribution at the same time as using the beam. Our focus on simplicity of use saves user time, and our integrated resetting mechanism ensures stable calibration. Our ability to divert ~30% of beam power for high beam intensity (1014 - 1016) measurements enhances the dynamic range and reduces heating. In Phase II, Advent Diamond proposes to further develop the Phase I technology for compact
