| - | * We need a laser beam that is perpendicular to the silicon bulk and that remains perpendicular also when we move it along $x$, $y$, and $z$. Is it possible to mechanically constrain the rails and the support for the module? Or is it better to put something on the rails that allows us to regulate the alignment? We can verify alignment by looking at signal from sensors. Maximum angle of inclination with respect to the silicon bulk is $0.5^\circ$. | + | * We need a laser beam that is perpendicular to the silicon bulk and that remains perpendicular also when we move it along //x,// //y//, and //z//.

| * How can we minimize vibrations of the module? In the previous test stand: a pre-tensioning plastic block put between the back wall of the test box and the module inhibits these vibrations. The exact pre-tension can be adjusted by placing hard-plastic disks between the block and the wall. | * How can we minimize vibrations of the module?
