Proposed set-up for performing SMS using high-speed shutters. Axes of shutters are parallel to the X-ray beam. Focusing system (A), anti-shutter (B), sample or near-single-line resonant absorber (C), shutter (D), slits (E), sample or near-single-line resonant absorber (F), detector (G). For time-domain measurements a nuclear resonant sample is placed at position C, while nothing is placed at position F, and the detector needs a nanosecond time-resolution. For energy-domain measurements a near-single-line resonant material is mounted on a velocity transducer at position C (F), while the sample is placed at F (C), with the detector not requiring time resolution. |
