The newly presented concept, published in the journal Physical Review Letters (PRL), addresses the energy spread, one of the most pressing challenges of this novel technology, and could enable applications such as compact free-electron lasers, measuring just dozens of meters instead of kilometres as today.

Assume the solar energy spread equally in this distance, that's about 3*10^17 km2.

When Technology And The Future Of The Sun Collide

With its significantly smaller energy spread as compared to traditional thermal field emission sources, the cFEG provides a boost in image contrast owing to an improvement in the envelope functions, particularly in the sub-5[Angstrom] resolution region.

Thanks to the energy compression property, the SS signal which had energy spread over time, it now can be turned into single pulse.

The numerical simulations imply that the relativistic ponderomotive acceleration can produce high quality electron bunches characterized by an extremely short bunch duration of sub-femtosecond, the energy spread less than 1%, and the normalized transverse emittance less than 10: mmmrad.

Nevertheless, businesses, particularly small and medium enterprises (SMEs), that don't increase their headcount may struggle to grow, with their time and energy spread too thin handling non-core tasks.

The UC source improves imaging resolution at low accelerating voltages by decreasing the energy spread among beam electrons, which reduces chromatic aberration and permits the beam to be focused into a smaller spot on the sample surface.

But that's the difference between taking one of Mike Tyson's punches to the head, and receiving that same energy spread out over a week; one will kill you, the other you won't even notice.

But does it work?

Second-generation devices helped improve concerns of energy spread by hooking a computer up to measure the current.

Monopolar, bipolar, and laser instruments available at that time were inherently risky to use along the pelvic sidewall because of their potential for 1) considerable thermal energy spread beyond the area of treatment (bipolar, NG:YAG laser, monopolar) and 2) unreliable hemostasis (C[O.sub.2] laser).

While much of the quake's energy spread along the planet's surface, some radiated downward, traveled through Earth's core and then returned to the surface in Japan, where more than 700 seismometers picked up the vibes.
