An Australian research group will use their new ultra-fast timing technology in combination with a new, extremely bright light source, the FERMI Free Electron Laser, Italy. FERMI makes picosecond wide light pulses - the timing technology measures times significantly shorter than a nanosecond. In combination, the way intense light effects the structure of atoms & molecules is studied, leading to an in-depth understanding of the processes involved. The new detector technology will be characterised using an electron recycling spectrometer, a new method for making electron beams of a particular energy by storing electrons in a racetrack orbit.

澳大利亚的一个研究小组将使用他们新的超快计时技术，并结合一种新的、极其明亮的光源--意大利费米自由电子激光。费米制造皮秒宽的光脉冲--计时技术测量的时间比纳秒短得多。结合起来，研究强光影响原子和分子结构的方式，导致对涉及的过程的深入理解。新的探测器技术将使用电子回收光谱仪来表征，这是一种通过在赛道轨道上存储电子来制造特定能量的电子束的新方法。
