Title
|
Photo of the world's most powerful X-ray laser at the European XFEL
|
|
Description
|
The extremely intense X-ray beam excites the nitrogen in the air to glow when the molecules cross its path. Despite the extremely high intensity of the beam, the glow of the nitrogen is comparatively weak and would not be easily visible to the naked eye. The beam only becomes as clearly visible as in the photo in complete darkness and with an exposure time of 90 seconds.
