One of the key problems of modern relativistic nuclear physics is the study of the phase diagram of strongly interacting matter. These experiments try to answer the question of how the transition of the QGP to the hadron gas occurs. To resolve such ambitious problems of studying hot and dense baryonic matter occurring in the relativistic heavy ion collisions, a new mega set-up is currently being developed at JINR: Multi-Purpose Detector (MPD) at NICA collider [1]. The main element of this MPD set-up it will be tracking system, required for the precise determination of track vertices with subsequent track reconstructions of all detected charged particles in a wide range of transverse momentum and pseudo rapidity.
The monolithic active pixel sensors based on CMOS technology are also being considered as building block for the construction of the vertex and inner tracker of the NICA MPD. These sensors were developed for the upgraded Inner Tracing System of ALICE experiment in CERN [2].
In this overview the properties and characteristics of multicomponent detector modules as basic elements for the precise determination of primary and secondary vertices together with new ultralight, radiation-transparent carbon fiber support structures (all detector modules are mounted on these structures) will be reported. Also possible use of these technologies for the experiments SPD, BM@N and NA61/SHINE will be discussed.
The reported study was funded by RFBR according to the research project № 18-02-40075.
