“…With respect to FELs, which produce femtosecond x-ray pulses, XRD has been used to study lasershocked copper [21] and silicon dioxide [22], while XPCI has been used to visualize shock wave propagation in diamond [23] at the Linac Coherent Light Source (LCLS) in the USA. XRD of laser-induced lattice dynamics in gold has also been performed at the SPring-8 Angstrom Compact Free Electron Laser in Japan [24]. The LCLS has built a dedicated end station for dynamic compression (matter at extremes) [25].…”

IntroductionThe properties of materials are driven to extreme conditions under high pressures, the highest of which is generated by shock compression. First described by George Gabriel Stokes in 1851 [1], 'a shock is a travelling wave front across which a discontinuous, adiabatic jump in state variables takes place'. Investigations of materials under shock compression cast light on a broad range of phenomena that are not fully understood in the areas of high-energy-density physics, earth and planetary sciences, aerospace engineering, and materials science. The three main progenitors of shock compression can be considered as: explosion, impact, and plasma [2]. Respectively, the most popular platforms for shock wave generation in the AbstractA high-power, nanosecond pulsed laser impacting the surface of a material can generate an ablation plasma that drives a shock wave into it; while in situ x-ray imaging can provide a timeresolved probe of the shock-induced material behaviour on macroscopic length scales. Here, we report on an investigation into laser-driven shock compression of a polyurethane foam and a graphite rod by means of single-pulse synchrotron x-ray phase-contrast imaging with MHz frame rate. A 6 J, 10 ns pulsed laser was used to generate shock compression. Physical processes governing the laser-induced dynamic response such as elastic compression, compaction, pore collapse, fracture, and fragmentation have been imaged; and the advantage of exploiting the partial spatial coherence of a synchrotron source for studying low-density, carbon-based materials is emphasized. The successful combination of a high-energy laser and ultra high-speed x-ray imaging using synchrotron light demonstrates the potentiality of accessing complementary information from scientific studies of laser-driven shock compression.

X-ray free-electron laser (XFEL) pulses from SPring-8 Ångstrom Compact free-electron LAser (SACLA) with a temporal duration of <10 fs have provided a variety of benefits in scientific research. In a previous study, an arrival-timing monitor was developed to improve the temporal resolution in pump-probe experiments at beamline 3 by rearranging data in the order of the arrival-timing jitter between the XFEL and the synchronized optical laser pulses. This paper presents Timing Monitor Analyzer (TMA), a software package by which users can conveniently obtain arrival-timing data in the analysis environment at SACLA. The package is composed of offline tools that pull stored data from cache storage, and online tools that pull data from a data-handling server in semi-real time during beam time. Users can select the most suitable tool for their purpose, and share the results through a network connection between the offline and online analysis environments.

“…To enable this, we employed unique accelerator technologies: a low emittance injector with a thermionic electron gun (e-gun) and a velocity bunching system; a high-gradient normal-conducting C-band linac; and a short-period in-vacuum undulator [4]. Combining these devices with state-of-the-art X-ray optics [5,6], we have steadily generated XFEL light for users more than 4000 h in FY2016, allowing researchers to produce a number of important scientific results in the fields of biology [7][8][9][10][11][12], chemistry [13][14][15][16], materials science [17][18][19][20], high-energy density science [21], and non-linear X-ray optics [22][23][24][25][26]. The success of SACLA has promoted the development of similar compact XFEL facilities, such as SwissFEL at Paul Scherrer Institut in Switzerland [27].…”

Abstract:This article reports the current status of SACLA, SPring-8 Angstrom Compact free electron LAser, which has been producing stable X-ray Free Electron Laser (XFEL) light since 2012. A unique injector system and a short-period in-vacuum undulator enable the generation of ultra-short coherent X-ray pulses with a wavelength shorter than 0.1 nm. Continuous development of accelerator technologies has steadily improved XFEL performance, not only for normal operations but also for fast switching operation of the two beamlines. After upgrading the broadband spontaneous-radiation beamline to produce soft X-ray FEL with a dedicated electron beam driver, it is now possible to operate three FEL beamlines simultaneously. Beamline/end-station instruments and data acquisition/analyzation systems have also been upgraded to allow advanced experiments. These efforts have led to the production of novel results and will offer exciting new opportunities for users from many fields of science.
