Sample Stacks
The Sample Stacks solution consists of three identical heavy loads (700 kg) and extremely high precision Sample Positioning Stacks for ISIS Target Station 2, Rutherford Appleton National Laboratory, UK. The first one was delivered in 2008, and two more in 2012.
The Sample Positioning Stacks have six (seven in 2012 version) degrees of freedom and load capacity.
The total height of the assembly in the lower position is 990 mm. All motions are encoded and can be operated in closed-loop, providing even higher accuracy. The 700 kg load capacity with accuracies as above are valid for +/-8° on the crossed arcs, and with +/- 50 mm offset in y-translation with a center of mass at 550 mm above the top plate. The 150 kg load capacity with accuracies as above is valid for +/-20° on the crossed arcs, and with +/- 300 mm offset in y-translation with a center of mass at 550 mm above the top plate.
Sample stacks are produced according to customer requirements.
