|

|
||||
*** Goal
|
||||
The objective is to estimate how much perturbation is injected in the system by the control systems of each stages of the micro station.
|
||||
|
||||
Geophones are located on the structure.
|
||||
Each stage is turned on and off.
|
||||
The signals of the geophones are then compared when the stage is on and off.
|
||||
|
||||
*** Results
|
||||
- The translation stage seems to have effect on the tilt stage at 20Hz.
|
||||
- The Tilt stage and the Hexapod control systems have no effect on the motion of the other stages.
|
||||
- The spindle stage control system seems to induce a motion of the Hexapod on the Z direction around 20Hz.

||||

Each stage is statically moved of all its stroke on after the other.
|
||||
A metrology element is located at the sample position and its motion is measured in translations and rotations.
|
||||
For each small displacement, the stage is stopped and the motion of the sample is recorded and averaged.
