Powerful picosecond generators are in demand in various fields of experimental electrophysics to produce ultrashort electron beams and X-ray pulses in vacuum diodes and to form runaway electron flows in gases.
They also have applications in high-power microwave electronics, but researchers are constantly striving to obtain shorter and more powerful pulses.
In Review of Scientific Instruments, by AIP Publishing, scientists showed compact solid-state pulse generators could generate electrical pulses of less than one-billionth of a second in duration and up to 50 billion watts in power.
“For comparison, the most powerful hydroelectric power plant in China has an output power of 22.5 billion watts,” said Sergei Rukin, one of the authors.
Improving picosecond generators and mastering higher peak power levels in the picosecond range sets the groundwork for new applications in the coming years.
“This also happened with the development of powerful nanoscecond pulsed devices during the last 60 years,”
Zeiss’ full-frame compact ZX1 compact full-frame camera debuted in 2018 with built-in Lightroom CC and other unusual features, but we’ve barely heard a peep about it since. Now, the camera has suddenly gone on pre-order for $6,000 at B&H Photo, nearly two years after it was supposed to go on sale (via DPReview).
The ZX1 has high-end specs for a compact, including a 37.4-megapixel sensor, 35mm fixed Zeiss Distagon F/2 lens, 255 area autofocus (B&H Photo doesn’t specify which type) and a 4.3-inch 1,280 x 720 pixel display. You can use the latter to run a version of Adobe Lightroom CC, though you’ll need a subscription if you want to share edited images to a desktop app, according to the Q&A. It also comes with a WiFi, Bluetooth and a USB Type-C interface so you can transfer and and upload your files to cloud services.
Scientists developing a compact version of a nuclear fusion reactor have shown in a series of research papers that it should work, renewing hopes that the long-elusive goal of mimicking the way the sun produces energy might be achieved and eventually contribute to the fight against climate change.
Construction of a reactor, called Sparc, which is being developed by researchers at the Massachusetts Institute of Technology and a spinoff company, Commonwealth Fusion Systems, is expected to begin next spring and take three or four years, the researchers and company officials said.
Although many significant challenges remain, the company said construction would be followed by testing and, if successful, building of a power plant that could use fusion energy to generate electricity, beginning in the next decade.
This ambitious timetable is far faster than that of the world’s largest fusion-power project, a multinational effort in Southern France called ITER, for International
MinisForum has been making some interesting moves in the last few months with their computing platforms, ranging from the DMAF5 based on the Ryzen 3000H-series SoCs to the Ice Lake-based DeskMini X35G. In early August, they reached out to us to pitch their first mini-PC sporting a discrete GPU – the EliteMini H31G. Intrigued by their claims of being able to cram a 65W CPU and a 75W GPU in a chassis measuring approximately 15cm x 15cm x 6cm, we accepted their offer of a review unit to put through our standard mini-PC benchmarking process. The sample arrived last week, but we have a few thoughts to share.
The EliteMini H31G is a compact mini-PC smaller than other dGPU-equipped mini-PCs we have reviewed before like the ASRock DeskMini Z370 GTX 1060 and the Ghost Canyon NUC. A look at the unit reminded me of the GIGABYTE BRIX Gaming BXi5G-760 we
Apple’s recent September event saw the launch of new iPads and two new versions of the Apple Watch but no new iPhones. Apple is expected to hold another event in October where-in it will announce the iPhone 12 line-up. The Cupertino-based tech giant looks set to launch four new iPhones this year and the smallest member of the family will reportedly be called the iPhone 12 Mini.
While multiple 5G capable Android smartphones have been launched already, iPhones still lack this crucial feature. With the iPhone 12 series, Apple is finally expected to make the transition to 5G connectivity. However, the feature might not be coming to all four smartphones. According to The Wall Street Journal’s analyst Tom Forte (via Gizchina), the iPhone 12 Mini will not feature 5G connectivity.
