Direct observations of a complex coronal web driving highly structured slow solar wind Astronomy

Posted by in categories: augmented reality, solar power, space

Thus, our SUVI observations captured direct imprints and dynamics of this S-web in the middle corona. For instance, consider the wind streams presented in Fig. 1. Those outflows emerge when a pair of middle-coronal structures approach each other. By comparing the timing of these outflows in Supplementary Video 5, we found that the middle-coronal structures interact at the cusp of the southwest pseudostreamer. Similarly, wind streams in Supplementary Figs. 1 3 emerge from the cusps of the HCS. Models suggest that streamer and pseudostreamer cusps are sites of persistent reconnection30,31. The observed interaction and continual rearrangement of the coronal web features at these cusps are consistent with persistent reconnection, as predicted by S-web models. Although reconnection at streamer cusps in the middle corona has been inferred in other observational studies32,33 and modelled in three dimensions30,31, the observations presented here represent imaging signatures of coronal web dynamics and their direct and persistent effects. Our observations suggest that the coronal web is a direct manifestation of the full breadth of S-web in the middle corona. The S-web reconnection dynamics modulate and drive the structure of slow solar wind through prevalent reconnection9,18.

A volume render of log Q highlights the boundaries of individual flux domains projected into the image plane, revealing the existence of substantial magnetic complexity within the CH–AR system (Fig. 3a and Supplementary Video 7). The ecliptic view of the 3D volume render of log Q with the CH–AR system at the west limb does closely reproduce elongated magnetic topological structures associated with the observed coronal web, confined to northern and southern bright (pseudo-)streamers (Fig. 3b and Supplementary Video 8). The synthetic EUV emission from the inner to middle corona and the white-light emission in the extended corona (Fig. 3c) are in general agreement with structures that we observed with the SUVI–LASCO combination (Fig. 1a). Moreover, radial velocity sliced at 3 R over the large-scale HCS crossing and the pseudostreamer arcs in the MHD model also quantitatively agree with the observed speeds of wind streams emerging from those topological features (Supplementary Figs. 4 and 6 and Supplementary Information). Thus, the observationally driven MHD model provides credence to our interpretation of the existence of the complex coronal web whose dynamics correlate to the release of wind streams.

The long lifetime of the system allowed us to probe the region from a different viewpoint using the Sun-orbiting STEREO-A, which was roughly in quadrature with respect to the Sun–Earth line during the SUVI campaign (Methods and Extended Data Fig. 6). By combining data from Solar Terrestrial Relations Observatory-Ahead’s (STEREO-A) extreme ultraviolet imager (EUVI)34, outer visible-light coronagraph (COR-2) and the inner visible-light heliospheric imager (HI-1)35, we found imprints of the complex coronal web over the CH–AR system extending into the heliosphere. Figure 4a and the associated Supplementary Video 9 demonstrate the close resemblance between highly structured slow solar wind streams escaping into the heliosphere and the S-web-driven wind streams that we observed with the SUVI and LASCO combination. Due to the lack of an extended field of view, the EUVI did not directly image the coronal web that we observed with SUVI, demonstrating that the SUVI extended field-of-view observations provide a crucial missing link between middle-coronal S-web dynamics and the highly structured slow solar wind observations.

Thermonuclear neutron emission from a sheared-flow stabilized Z-pinch

Posted by in categories: augmented reality, nuclear energy, transportation

Year 2021 viable fusion reactor in a z pinch device which is compact enough to fit in a van or airplane ✈️ 😀


The fusion Z-pinch experiment (FuZE) is a sheared-flow stabilized Z-pinch designed to study the effects of flow stabilization on deuterium plasmas with densities and temperatures high enough to drive nuclear fusion reactions. Results from FuZE show high pinch currents and neutron emission durations thousands of times longer than instability growth times. While these results are consistent with thermonuclear neutron emission, energetically resolved neutron measurements are a stronger constraint on the origin of the fusion production. This stems from the strong anisotropy in energy created in beam-target fusion, compared to the relatively isotropic emission in thermonuclear fusion. In dense Z-pinch plasmas, a potential and undesirable cause of beam-target fusion reactions is the presence of fast-growing, “sausage” instabilities. This work introduces a new method for characterizing beam instabilities by recording individual neutron interactions in plastic scintillator detectors positioned at two different angles around the device chamber. Histograms of the pulse-integral spectra from the two locations are compared using detailed Monte Carlo simulations. These models infer the deuteron beam energy based on differences in the measured neutron spectra at the two angles, thereby discriminating beam-target from thermonuclear production. An analysis of neutron emission profiles from FuZE precludes the presence of deuteron beams with energies greater than 4.65 keV with a statistical uncertainty of 4.15 keV and a systematic uncertainty of 0.53 keV. This analysis demonstrates that axial, beam-target fusion reactions are not the dominant source of neutron emission from FuZE. These data are promising for scaling FuZE up to fusion reactor conditions.

AI-designed structured material creates super-resolution images using a low-resolution display

Posted by in categories: augmented reality, robotics/AI, virtual reality, wearables

One of the promising technologies being developed for next-generation augmented/virtual reality (AR/VR) systems is holographic image displays that use coherent light illumination to emulate the 3D optical waves representing, for example, the objects within a scene. These holographic image displays can potentially simplify the optical setup of a wearable display, leading to compact and lightweight form factors.

On the other hand, an ideal AR/VR experience requires relatively to be formed within a large field-of-view to match the resolution and the viewing angles of the human eye. However, the capabilities of holographic image projection systems are restricted mainly due to the limited number of independently controllable pixels in existing image projectors and spatial light modulators.

A recent study published in Science Advances reported a deep learning-designed transmissive material that can project super-resolved images using low-resolution image displays. In their paper titled “Super-resolution image display using diffractive decoders,” UCLA researchers, led by Professor Aydogan Ozcan, used deep learning to spatially-engineer transmissive diffractive layers at the wavelength scale, and created a material-based physical image decoder that achieves super-resolution image projection as the light is transmitted through its layers.
