Compact solid-state pulsed power generators achieve shorter, more powerful pulses — ScienceDaily

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,”

Ultrafast fiber laser produces record high power

Researchers have developed an ultrafast fiber laser that delivers an average power more than ten times what is available from today’s high-power lasers. The technology is poised to improve industrial-scale materials processing and paves the way for visionary applications.


Michael Müller, a Ph.D. student of Prof. Jens Limpert from the Friedrich Schiller University’s Institute of Applied Physics and the Fraunhofer Institute of Institute for Applied Optics and Precision Engineering in Jena, Germany, will present the new laser at the all-virtual 2020 OSA Laser Congress to be held 12-16 October. The presentation is scheduled for Tuesday, 13 October at 14:30 EDT.

High power without the heat

In lasers, waste heat is generated in the process of light emission. Laser geometries with a large surface-to-volume ratio, such as fibers, can dissipate this heat very well. Thus, an average power of about 1 kilowatt is obtained from today’s high-power

Apple may stop shipping power adapters with iPhone SE, other current devices

Apple is expected to ship new “iPhone 12” models without an AC power adapter, but it could also do the same for previously released devices like the iPhone SE.

The lack of a charging brick in the box is said to be a cost-saving move for this year’s iPhone models. Apple also stopped shipping power adapters with the Apple Watch Series 6, citing environmental reasons.

In a tweet on Tuesday, Bloomberg’s Mark Gurman suggested that the Cupertino tech giant would also stop shipping charging bricks with previously released iPhone models that “it’ll keep selling.”

Although Gurman doesn’t specify, his prediction suggests that Apple will — or already has — change the packaging for current

Tech Stocks Power Markets Higher

U.S. stocks jumped sharply Monday, propelled by technology stocks that led major indexes to their highest closing values in nearly six weeks.

All three major U.S. indexes climbed for the fourth consecutive session. The S&P 500 rose 57.09 points, or 1.6%, to 3534.22—its second-highest close in history. The Dow Jones Industrial Average rallied 250.62 points, or 0.9%, to 28837.52.

The Nasdaq Composite surged 296.32 points, or 2.6%, to 11876.26, its third-highest close. All three indexes are closing in on their early September highs after a recent stretch of volatility.

Megacap companies including

Apple

and

Amazon.com

were among the strongest performers, jumping 6.4% and 4.8%, respectively. Apple is set on Tuesday to unveil a 5G-enabled iPhone, which some investors hope could fuel the kind of sizable growth that stemmed from previous technological advancements for the iPhone.

Introduction to the fundamental technologies of power density

To better understand the fundamental technologies of high-power-density designs, in this article I’ll examine the four most important aspects of high-power-density solutions:

  • Reduced loss generation.
  • Optimal topology and control selection.
  • Effective heat removal.
  • Reducing system volume through mechanical and electrical component integration.

I’ll also demonstrate how partnering with TI, and using advanced technological capabilities and products that support these four aspects, can help improve your efforts to achieve high-power-density figures.

But first, let’s define power density and highlight some important details when comparing solutions based on their power-density figures.

What is power density?

For power-management applications, the definition of power density seems straightforward: it is the rated (or nominal) output power of the converter divided by the volume that the converter occupies as shown in Figure 1.

But even this simple definition demands a lot of clarification if you want to compare power supplies, based on their power-densities.

The output

Annabelle Southcoat, Government Scientist, On The Positive Power Of Champions In The Workplace

In honor of #WorldMentalHealthDay I’d like to share with a story from another inspirational woman in my network. Annabelle Southcoat is a genuine polymath – someone whose intellectual curiosity and drive for humanity and social justice has led her down so many fruitful paths already. Her story is interesting because she so nearly wasn’t. Her story is relevant to business leaders because she demonstrates the value of authentic adjustments to our inclusion practice and how, with the right champion, we can change the course and direction of lives. Ms Southcoat is now a Psychologist at the UK Defence, Science and Technology Laboratory (DSTL) a drummer in a band, an innovative thinker and a pussy cat mother.

The Significance Of Childhood Narratives

In Ms Southcoat’s own words. ”I’m also a dyslexic, gay, trans woman (though I tend to just say woman these days) and

Without nuclear power, the world’s climate challenge will get a whole lot harder

The Covid-19 crisis not only delivered an unprecedented shock to the world economy. It also underscored the scale of the climate challenge we face: Even in the current deep recession, global carbon emissions remain unsustainable.

If the world is to meet energy security and climate goals, clean energy must be at the core of post-Covid-19 economic recovery efforts. Strong growth in wind and solar energy and in the use of electric cars gives us grounds for hope, as does the promise of emerging technologies like hydrogen and carbon capture. But the scale of the challenge means we cannot afford to exclude any
