Ultrafast relativistic electron diffraction<br />
Real time resolution <strong>of</strong> atomic motion<br />
Pulse length (100fs) comparable to time-scale <strong>of</strong> atomic<br />
<strong>and</strong> molecular motion<br />
De Broglie wavelength λ = h/p ~ 0.3 pm (for e- @ 5 MeV)<br />
Ultra relativistic beam easier to h<strong>and</strong>le space charge,<br />
larger bunch population <strong>and</strong> shorter bunch<br />
