By counting the number of such X-rays while scanning the frequency of the laser pulse, the team could make a very precise measurement of the photon energy required to drive the 2s-2p transition.
The pilots are expected to cooperate and contribute to common measurement methods and reporting formats in order to assess energy savings and carbon footprint reduction together.
