Your units don't add up: W = J/s -> W*s = J. What you calculated was 10^(-7) J, not W.

- sbierwagen 7y agoFortunately, the paper calculates pulse power: >The median pulse energy is 10 μJ at 905 eV and 25μJ at 570 eV. However, due to the intrinsic fluctuations of SASE XFELs we observe pulses well above the mean value (up to 250μJ for 570 eV, corresponding to a peak power in the hundreds of gigawatts). The only power consumption number in the paper is an aside that notes the magnetic chicane in the electron beamline is spiked at 10 kiloamps. (At how many volts? How much power does the rest of the laser consume?) Free-electron lasers are many things, but efficient isn't one of them.
