The electrons within the field are staggered, so that those further back have more energy than those in the front. It&#8217;s sort of like runners staggered at the start of a track race, Emma explained.<\/p>\n<p>&#8220;We then send them around a bend, so the electrons in the back catch up with electrons in front, and then at the end, you have a bunch of electrons together in a focused beam.&#8221;<\/p>\n<p>The problem with this approach is that as they accelerate, electrons emit radiation and lose energy, so the quality of the beam deteriorates. That creates a tradeoff between beam energy and quality. &#8220;We can&#8217;t apply traditional methods to compress bunches of electrons at the submicron scale, while also preserving beam quality,&#8221; Emma said.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Lasers_for_the_win\"><\/span>Lasers for the win<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>To solve this issue, SLAC researchers compressed billions of electrons into a length less than one micrometer using a laser-based shaping technique originally developed for X-ray free-electron lasers, such as SLAC&#8217;s Linac Coherent Light Source (LCLS).<\/p>\n<p>&#8220;The big advantage of using a laser is that we can apply an energy modulation that&#8217;s much more precise than what we can do with microwave fields,&#8221; Emma said.<\/p>\n<p>But it&#8217;s not as simple as just shooting a few lasers down a tunnel. &#8220;We have a one-kilometer-long machine, and the laser interacts with the beam in the first 10 meters, so you have to get the shaping exactly right, then you have to transport the beam for another kilometer without losing this modulation, and you have to compress it,&#8221; Emma said. &#8220;So it wasn&#8217;t easy.&#8221;<\/p>\n<p>After several months of testing and finessing their laser shaping technique, Emma and his team can now repeatedly produce high energy, femtosecond-duration, petawatt peak power electron beams that are about five times higher in current than what could previously be achieved.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"An_incredible_new_tool\"><\/span>An incredible new tool<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This new beam will allow scientists to probe a whole <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/watch-movies-tv-seriess\/\" data-internallinksmanager029f6b8e52c=\"8\" title=\"Watch Movies &amp; TV Series\" target=\"_blank\" rel=\"noopener\">series<\/a> of natural phenomena, including testing hypotheses in quantum physics, materials science, and astrophysics.<\/p>\n<p>In astrophysics, for example, this beam can be directed to a solid or gas target to create a filament similar to those seen in stars. &#8220;Scientists know that these filaments occur, but now we can test how they occur and evolve in the lab with a level of power we haven&#8217;t had before,&#8221; Emma said.<\/p>\n<div class=\"ads w-100 my-4 article-main__more bg-light p-3 border\" aria-hidden=\"true\">\n<p class=\"mb-3\">\n        Discover the latest in science, tech, and space with over <strong>100,000 subscribers<\/strong> who rely on Phys.org for daily insights.<br \/>\n        Sign up for our <a rel=\"nofollow\" target=\"_blank\" href=\"https:\/\/sciencex.com\/help\/newsletter\/\" target=\"_blank\">free newsletter<\/a> and get updates on breakthroughs,<br \/>\n        innovations, and research that matter\u2014<strong>daily or weekly<\/strong>.\n    <\/p>\n<\/div>\n<p>Fellow FACET-II researchers pounced on the more powerful beam and have already applied it to advancing plasma wakefield <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>.
