Mechanical design of interaction chamber for the ELIADE array at ELI-NP

This paper presents the analysis of the vibration of the interaction chamber (IC), a medium vacuum chamber, that uses linear actuators controlled on the basis of complex signals acquired from the IC and its surrounding space. This research mainly focuses on the kinematic precision assured by the mechanical system represented by the IC with component parts. The performance obtained by the quadrature acting system for the sample holder will be compared with the error introduced. The software implements two loops: the image acquisition from the digital camera and the detection of the target for the X–Y linear stage. Considering the vibration of the structure, the geometry of the whole system, the kinematics, and the dynamic model are detailed; the hardware’s influence, in conjunction with the corresponding firmware of the tracking installation, is analyzed with regard to positioning precision and dynamics. For the IC, the transmissibility from the ground to the target (which is an important measure for the correct functioning of the system) was determined. As a result, it is necessary to re-design the target’s lever in order to reduce the vibrations during the experiments.This paper presents the analysis of the vibration of the interaction chamber (IC), a medium vacuum chamber, that uses linear actuators controlled on the basis of complex signals acquired from the IC and its surrounding space.
