X-ray diffraction studies of laser-shocked crystals
Published 2016“…This technique is applied to two different experiments on tantalum. The first provides a measurement of the timescale for plastic deformation, which we find similar to comparable experiments in copper, while the second provides the first <em>in situ</em> of observation of twinning in shock compressed metal.…”

Experimental characterization of a single-shot spectrometer for high-flux, GeV-scale gamma-ray beams
Published 2023-10-01“…The spectrometer has been experimentally characterized using a bremsstrahlung source obtained at the Apollon laser facility during the interaction of laser-wakefield accelerated electron beams (maximum energy of 1.7 GeV and overall charge of 207±62 pC) with a 1 mm thick tantalum target. Experimental data confirms the possibility of performing single-shot measurements, without the need for accumulation, with a high signal-to-noise ratio. …”
