Abstract The ELI-NP Array of Detectors (ELIADE) is a project dedicated to be
the main experimental setups in order to use in practical applications the gammaray beam. The project is developed at ELI-NP Bucharest. The reaction chamber for
ELIADE array with all their devices are the goal of this research team. The level
off the research activities in ELI Institute imposes to obtain high precision of the
experiments. The study of the small deformation and the vibration of the equipment
becomes important. All the parts of the reaction chamber, to a greater or lesser
extent, consist of elastic elements. In the experiment, conducted by the Institute of
Atomic Physics, in connection with the ELIADE project, precision is so important
that it requires extremely small or undetected vibration of the device. Finite Element
Method is used to model the system and the sensitive element, the fixing device of
the target has been studied.
1 Introduction
Previous studies [1, 2] have analyzed the possibility of modeling the interaction
chamber and the influence of constructive parameters on system vibrations. To
accomplish this, a previous dynamic analysis [3–5] was made to determine to what
extent the rigid motion of the system influences the response to vibrations. In the
present paper, vibration analysis of the system as a whole and of the target fixing
rod is performed. This element has been shown to present vulnerabilities from the
point of view of design, resulting in a pronounced amplification of an external excitation for certain frequency ranges. The interaction chamber is clamped on two plans
where two actuators assure the movement of the interaction chamber on gamma beam
direction. The kinematics of the acting system was designed and simulated. In order
