Scientists and specialists of the Joint Institute for Nuclear Research tell about detectors system and superconductive magnet for NICA/MPD.

At the NICA collider that is under construction in the Veksler and Baldin Laboratory of High Energy Physics at one of the two beams cross points there will be the experimental facility MPD (Multi-Purpose Detector) aimed at analysis of heavy ion collisions in the field of large baryon density never studied before.

During experiments, researchers will have to deal with a large number of charged particles (more than a thousand). That is why the detector is supposed to successfully identify products of nuclear collisions and precisely measure their parameters. MPD consists of various subsystems of detectors that complement each other. They are necessary to measure energy, charge and types of charged particles. TPC (Time Projection Chamber) is the general detector in MPD that is used for registration of charged particles’ tracks and their identification in the MPD area.

Vladimir Kekelidze, Director of the JINR Veksler and Baldin Laboratory of High Energy Physics: “Almost 2 thousand charged particles produced in each interaction must be detected in MPD. There should be 7 thousand of such interactions per 1 second. Each of such events must be allocated by time, all tracks must be reconstructed, all parameters – measured, recorded on computer and transmitted for further processing. It is worth mentioning that such detectors are employed at all large facilities at CERN, in Brookhaven Laboratory. We followed the same example but we are improving the detector according to the latest technological developments.”
