Abstract:

Solid-state or crystal acceleration has for long been regarded as an attractive frontier in advanced particle acceleration. However, experimental investigations of solid-state acceleration mechanisms which offer [Formula: see text] acceleration gradients have been hampered by several technological constraints. The primary constraint has been the unavailability of attosecond particle or photon sources suitable for excitation of collective modes in bulk crystals. Secondly, there are significant difficulties with direct high-intensity irradiation of bulk solids, such as beam instabilities due to

Abstract:

New developments in crystal-based accelerator techniques for future μ+μ− colliders are outlined in the context of promising μ+μ− physics opportunities opening in the 250×250 GeV energy range (which will be discussed briefly). One of the novel schemes involves laser-driven high gradient (GeV/m) crystal acceleration combined with an effective crystal “cooler,” based on a stimulated radiation damping in a strain-modulated silicon crystal. The ultrastrong focusing environment of a crystal channel would provide effective transverse cooling without substantial blowup of the longitudinal momentum spr

Abstract In order to reduce the volume of compact neutron generators, a lot of investigations are carried out on generating high voltages by heating pyroelectric crystals with external heating. Laser irradiation is an effective non-contact heating method. Different laser parameters determine the crystal's temperature distribution, impacting the accelerating electric field. A preliminary study on the temperature distribution and pyroelectric current response of LiNbO3 heated by nanosecond pulse laser is presented, including both direct heating and heating with Cu and Ti disks adhered to the cry

Abstract:

A study on a new lithium salt accelerator was conducted in this paper aiming at the low temperature environment in deepwater cementing. The acceleration mechanism and comprehensive performance of the lithium salt accelerator were thoroughly discussed. Results show that the lithium salt accelerator can accelerate the low-temperature hydration rate of C3S and C2S by speeding up the rupture of protective hydration film and shortening the hydration induction period, and thereby significantly shortens the low-temperature thickening time and the 48-240 Pa transition time for the static gel strength

Quartz crystal oscillators are often used as the reference frequency sources, but they are very sensitive to accelerations. This paper discussed how accelerations affect oscillators’ frequency stability. The frequency shifts caused by gravity was shown through 2g-tipover experiment.

We studied the relationship between accelerations and oscillator’s frequency shifts by imposing sinusoidal and random vibrations onto the oscillator and observing th

Abstract:

For crystalline materials, an incident plane wave of electrons under conditions of strong dynamical scattering sets up a standing wave within the crystal. The intensity modulations of this standing wave within the crystal unit cell are a function of the incident beam orientation and the acceleration voltage. As the scattering events (such as inner shell excitations) that lead to characteristic x-ray production are highly localized, the x-ray intensities in turn, are strongly determined by the orientation and the acceleration voltage. For a given acceleration voltage or wavelength of the incide

The viability of spin-coating methods for the self-assembly of 150 nm diameter silica nanocolloids into large crystal structures on mica was investigated using different colloidal concentrations, accelerations, and rotational speeds.

Abstract:

In transmission electron microscopy (TEM), the usable thickness of specimens increases with the incident electron energy. Some Bloch wave calculations of electron channelling along the zone axis in the transmission case show that the energy level for the channelled electrons increases (negatively) with the incident electron energy due to the correction for relativistic effect. Similarly, for reflection electron diffraction geometry, the faster the incident electrons, the deeper they penetrate into the surface. The diffraction patterns are expected to approach steadily to that for a three-dimen

Abstract:

We report a cluster spin glass behavior, multiferroicity and magnetoelectric (ME) effects in the single crystals of 0.46[Formula: see text]-0.54[Formula: see text]. The crystals are found to possess a pseudo-cubic structure with a weak tetragonal distortion and show ferroelectricity at room temperature with a ferroelectric curie temperature of [Formula: see text] K. The cluster spin glass state in the crystal is evidenced by detailed dc and ac magnetic experiments, including thermo-remnant magnetization, aging effect, memory effect, etc. Magnetodielectric effects, poling enhanced magnetism, an

Abstract:

A 3D breathing MOF was synthesized for light-driven acceleration of the site-selective C(sp<sup>3</sup>)–H activation. The 1D channels of the assembled MOF can encapsulate reaction substrates via a breathing process that were observed by single-crystal X-ray analyses.

Abstract:

7075 aluminum alloy has been widely used because of its excellent mechanical properties. The fatigue crack acceleration induced by compressive overloading is detrimental to 7075 aluminum alloy in service, and the corresponding mechanisms are complex. To further reveal these mechanisms, the effect of microstructure on fatigue damage response ahead of the crack tip is simulated based on the damage-coupled crystal plasticity model for 7075 aluminum alloy. Results show that the ratchetting strain ahead of the crack tip at the compressive overload ratio of −3 is greater than that at the compressive

Abstract:

Crystallization of protein is still a "bottleneck" for the three-dimensional (3D) structure analysis of a protein molecule. Therefore, the study on the acceleration of the crystallization is important. Visuri et al. repoted, for the first time, that the crystallization of glucose isomerase (GI) crystals was significantly enhanced with increasing pressure [1], while they did not discuss further effects of pressure on the crystallization. We measured solubilities, growth rates of a crystal face, step velocities and two-dimensional (2D) nucleation rates, three-dimensional (3D) nucleation rates of

Abstract:

Acceleration environment (AE) simulation tests have been widely applied in various areas such as aviation, space, environmental medicine, medical science, biomedicine, and materials. Most existing AE simulation test methods adopt impact and flight overload simulation separately, which cannot realize the synchronous controllable loading of two-dimensional (2-D) dynamic acceleration. In this paper, we propose and implement an AE simulation test method using an air-cannon-started compound centrifugal turntable. Specifically, our method emphasizes two processes, i.e., orderly transition from impac
