The laser's impact generated fast-moving electrons that rapidly heated the surface of the copper wire, producing shock waves.

In a series of precise measurements, the scientists varied the timing between the laser pulse and the X-rays passing through the target.Artistic view of the imploding wire: a strong current of high-energy electrons heats up the surface, thus driving subsequent shockwaves which compress the wire radially.

Explains Dr. Alejandro Laso Garcia, lead author of the paper, “This combination of short-pulse laser and X-ray laser is unique in the world. It was only thanks to the high quality and sensitivity of the X-ray beam that we were able to observe an unexpected effect.”In a series of precise measurements, the scientists varied the timing between the laser pulse and the X-rays passing through the target. This allowed them to create a detailed “X-ray film” of the process.
