Abstract
The Multi-Purpose Detector (MPD) is designed to study heavy-ion collisions at the Nuclotron-based heavy Ion Collider fAcility (NICA) at JINR, Dubna. The detector will comprise a superconducting solenoid equipped with three dimensional tracking system composed of a silicon microstrip vertex detector followed by a large volume time-projection chamber and a particle identification system based on time-of flight measurements and calorimetry. In this paper a few parts of apparatus are described and their tracking and particle identification parameters are discussed in some detail.
