This alignment information will change when the target insert is full cold, but only on the scale of ~0.3 mm. The twist and rotation from contraction is a concern and it would be good to follow the above beam scanning procedure to understand these effects very well.
Crosshair Cross hair and pencil targets that can be loaded into the existing inserts are intended for target-beam alignment. Crosshair Cross hair targets can be made out of a standard target cell with CuNi wire running vertical and horizontal. We have fine control of the y-direction with the actuator table. We can also make a machine SS target of the length of the target cell (8 cm) with a circular profile sitting dead center of the target cell to help determine this location with scalars.
