The influence of vibrations on the position of the target in the interaction chamber of the ELI-NP facility represents an important element in any experiment with gamma beam rays. Also, several detection systems are provided around the interaction chamber for tracking the nuclear reactions that occur inside the interaction chamber. They are fixed with very high precision in relation to the interaction chamber. In addition to tracking the gamma ray beam, it must to know with great precision the position of the sample holder and of these detectors placed in laboratory. The precision required for a gamma-ray experiment is determined by the size of the studied material. If there is enough target material, then the precision is not important, but if we have a very small amount of material, then precision becomes significant. For a common experiment, accuracy is considered satisfactory for a value of ۲μm. The paper analyzes the influence of anthropogenic and natural vibrations on the position of the target, located at the end of a guide beam.
