- Install a fast diode and mirror (roughly at 45 degrees with respect to the beam) on the SC1 sample_x stage (CXI:SC1:MMS:02.RBV)
- The fast diode has a small area and is therefore difficult to align. Ideally, a Y stage (PP-30 piezo) is used to allow remote motion of the diode to align to the laser and x-rays.
- Due to the limited travel range of the long X-stage in SC1, the diode and mirror must be installed as far as reasonable towards the -X side, overhanging away from the carriage
- 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).
- Install a regular diode connected to the Acqiris on the sample chambe door and aligned the reflected laser beam on the mirror onto that diode.
- Repeat with the fs laser and maximize the acqiris signal by moving the diode on the chamber door.
- 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
- Determine the position of the X-ray spot at the IP using the clear YAG and the beam with 1x10-4 Transmission
