DiProI

MiniTIMER delay line

The MiniTIMER compact split and delay line can be set up inside the DiProI chamber before the sample region to split each FEL pulse into to branches and recombine them on the sample with tunable incidence angle and delay (in collaboration with the EIS-TIMER beamline). This set up has been used for transient grating, coherent anti-Stokes Raman scattering and time-resolved magnetic scattering experiments.
The typical crossing angle between the two beams is of about 6° and the delay can be scanned in the range of ±500 fs.
