JT-60SA nuclear fusion comes to life

Japan's fusion power project has produced first plasma at the JT-60SA research facility, the National Institutes for Quantum Science & Technology (QST) reported. The research will advance to the next phase, building and testing an experimental fusion reactor.

The JT-60SA facility was completed at QST in Naka, Ibaraki prefecture, in 2020, with Japan and Europe providing the funding. QST and Fusion for Energy (F4E) are the implementing agencies responsible for the manufacture of components, assembly and commissioning of JT-60SA.

JT-60SA was developed using much of the existing site infrastructure from the Japan Torus-60 upgrade experiment (JT-60U), which cuts project assembly time and costs, but most of the main components have been re-designed and manufactured.

The JT-60SA's central unit is around 16 metres high and 13 metres in diameter. It is the world’s second-largest plasma research facility exceeded only by the International Thermonuclear Experimental Reactor (ITER) under construction in France. Work undertaken by JT-60SA will support ITER.

Oct 2023:

The commissioning of the Equilibrium Field (EF) coils and Central Solenoid (CS) modules was completed up to 3 kA in October. Besides confirming that the each coil could be safely discharged by the quench protection circuits from plus or minus 3 kA, tests were also made on each coil to confirm the rapid response of the coils when high voltages were applied.

During the Inauguration Ceremony on 01 December a divertor plasma with one million amps of current was demonstrated

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

14 Oct 2020, being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station. The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station. previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
