Machine learning reveals hidden components of X-ray pulses
Ultrafast pulses from X-ray lasers reveal how atoms move at timescales of a femtosecond. That’s a quadrillionth of a second. However, measuring the properties of the pulses themselves is challenging. While determining a pulse’s maximum strength, or ‘amplitude,’ is straightforward, the time at which the pulse reaches the maximum, or ‘phase,’ is often hidden. A new study trains neural networks to analyze the pulse to reveal these hidden … ⌘ Read more
