Detector circular din scintilatori plastici utilizat la NICA (Dubna)
Diagram of the scintillation detector of small dimensions for luminosity measurements. Each detector has three planes of four rings centered at the collision axis.

Detector performance from plastic scintillators dedicated for absolute luminosity measurement at NICA(JINR-Dubna)
Responsible: Mădălina Cruceru

Taking into account the expertise in the performance of detector ensembles with scintillators and semiconductors, one of the research directions of DFNA is represented by the development of specialized detectors of small dimensions dedicated to be used in experiments conducted in the frame of the international collaborations.
