Step-by-step guide
Femtosecond timing in sample chamber 1 (SC1) at CXI.
- Install a fast diode and mirror (roughly at 45 degrees with respect to the beam) on the SC1 sample_x stage
- Roughly align the fast diode and mirror using the reference laser at the time tool (-4 mm in position but this will soon be changed to 0 mm. If the "out" position is 92 mm, then -4 mm, if 96 mm, then 0 mm).
- Insert a nozzle rod with both a clear YAG and a frosted YAG.
- At CXI, the clear YAGs are typically thinner, around 20 um, whereas the frosted YAGs are thicker, around 50 um
