The scintillating screen is inserted into the beam under an angle of 45°. Through a viewport, located at 90° with respect to the beam, a camera observes the screen.
The drawing of the scintillating screen setup on a flange with a target under 45° in respect to the beam.
The mechanical constituents of one Scintillating Screen Setup are the following parts:
The linear actuator moves the detector (scintillating screen and holder) into the beam center and out of the beam. The four different detectors are foreseen correspond to four different linear actuators.

Technical drawing of linear actuator with camera setup.
The optical constituents of one Scintillating Screen are the following parts:
The detector consists of the scintillating screen (target) and the target holder. The scintillating screen is a round disk of scintillating material (solid or coated material), fixed in a holder with permanent alignment marks outside the active area.
