| 5 | The R3B (Reactions with Relativistic Radioactive Beams) experiment is a versatile reaction setup with high efficiency, acceptance, and resolution for kinematically complete measurements of reactions with high-energy radioactive beams. With the commissioning of the new FAIR accelerator facility, the R3B setup will be relocated to the newly constructed High Energy Cave (HEC), where it will receive high-intensity primary and secondary beams from the Super-FRS (Super Fragment Separator). | ||

| 7 | The installation of detectors in this new cave demands precise alignment, which involves the use of scanning and surveying tools such as laser trackers, laser levels, and laser grids. Proper alignment is crucial to ensure the accurate positioning of detectors and to maintain the required tolerances in distances and angles for experimental setups. | ||

| 9 | The summer student will be involved in the following tasks: | ||
| 10 | * A bibliographical review of alignment systems used in similar large-scale experimental facilities. | ||
| 11 | * An evaluation of commercial solutions for the alignment and surveying of detector components. | ||
| 12 | * The preliminary design and proposal of a permanent alignment station capable of reliably (re)locating detectors in the cave according to the positional tolerances specific to each detector system. | ||

| 14 | This work will contribute to the successful relocation and calibration of the R3B setup in the High Energy Cave and ensure the experiment's readiness for high-precision measurements at FAIR. |
