That&#8217;s a quadrillionth of a second. However, measuring the properties of the pulses themselves is challenging. While determining a pulse&#8217;s maximum strength, or &#8216;amplitude,&#8217; is straightforward, the time at which the pulse reaches the maximum, or &#8216;phase,&#8217; is often hidden. A new study trains neural networks to analyze the pulse to reveal these hidden sub-components. Physicists also call these sub-components &#8216;real&#8217; and &#8216;imaginary.&#8217; Starting from low-resolution measurements, the neural networks reveal finer details with each pulse, and they can analyze pulses millions of times faster than previous methods.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2022-08-machine-reveals-hidden-components-x-ray.html\" target=\"_blank\" rel=\"nofollow noopener\">Machine learning reveals hidden components of X-ray pulses<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ultrafast pulses from X-ray lasers reveal how atoms move at timescales of a femtosecond.
