Silicon transistors are approaching their physical limit, calling for the emergence of a technological revolution. As acknowledged ultimate version transistor channels, 2D semiconductors interest development post-Moore electronics due to useful properties and all-in-one potentials. Here, promise current status reviewed, from materials devices integrated applications. First, we outline evolution challenges silicon-based circuits, followed by detailed discussion on preparation strategies van...
Abstract The energy deposition of ions in dense plasmas is a key process inertial confinement fusion that determines the α-particle heating expected to trigger burn wave hydrogen pellet and resulting high thermonuclear gain. However, measurements ion stopping are scarce mostly restricted velocities where theory agrees with data. Here, we report experimental data at low projectile near Bragg peak, force reaches its maximum. This parameter range features largest theoretical uncertainties...
In the last two decades, generation of intense ion beams based on laser-driven sources has become an extensively investigated field. The LIGHT collaboration combines a laserdriven source with conventional accelerator technology Expertise laser, plasma and physicists. Our installed multi-MeV beamline at GSI Helmholtzzentrum fuer Schwerionenforschung delivering proton bunches in subnanosecond regime. We investigate possible applications for this beamline, especially report we focus imaging...
We report on the experimental characterisation of laser-driven ion beams using a Thomson Parabola Spectrometer (TPS) equipped with trapezoidally shaped electric plates, proposed by Gwynne et al. [Rev. Sci. Instrum. 85, 033304 (2014)]. While pair extended (30 cm long) plates was able to produce significant increase in separation between neighbouring species at high energies, deploying trapezoidal design circumvented spectral clipping low energy end spectra. The shape plate chosen carefully...
We report on our latest transverse focusing results of subnanosecond proton bunches achieved with a laser-driven multi-MeV ion beamline. In the frame LIGHT collaboration, target normal sheath acceleration (TNSA) source based 6 m long beamline was installed. past years, beam transported and shaped by this The particle is collimated pulsed high-field solenoid rotated in longitudinal phase space radio-frequency cavity which leads to an energy compression spread...
Abstract 2D materials have been interested in recent years due to their unique properties and enormous potential various fields. In particular, ferroionics with both ferroelectricity ionic conductivity shed light on new possibilities for van der Waals nanoelectronics. Here, supported by theoretical calculations electrical characterizations, the reconfigurable ferroionic barristor that can be used multifunctional electronics including resistive devices steep‐slope transistors is reported....
To this day the interaction of high-intensity lasers with matter is considered to be a possible candidate for next generation particle accelerators. Within LIGHT collaboration crucial work merging laser driven ion source conventional accelerator technology has been done in past years. The simulation studies we report about are an important step providing short and intense mid-Z heavy beams future applications.
The new phase change mechanism that carbons in explosives are synthesized into ultrafine diamonds the process of detonation has been proposed. Within reaction zone, after explosive molecules decomposed firstly exist state gas-like free atoms, then unoxidized carbon atoms coagulate liquid droplets, and crystallize diamonds; some transformed graphites Taylor wave zone.
