TIMER
The TIMER instrument is purposedly designed to carry out FEL-based extreme ultraviolet transient grating experiments (XTG). Here, two non collinear FEL pulses generate an interference pattern at the sample with a spatial periodicity in the 2-200 nm range. The dynamic response to this nanoscale modulation is monitored via the diffraction of a third, time-delayed pulse. This XTG diffraction signal encodes information on several fundamental processes, ranging from transport phenomena to collective excitations and fast electron dynamics. |
