The "Tracking Detector Department" named in the past as "The Group of gas-discharge devices" was formed in 1972 at PNPI. A.G.Krivshich heads this department starting from 1982.
      The first proportional chambers, have been designed and produced at PNPI by this team in 1973.
From that time till now most of the gaseous particle detectors for the high-energy physics experiments, carried out by PNPI HEPhD in different world scientific centers, have been designed and produced by this department. It was proportional and drift chambers with different types of readout (anode readout, cathode strip readout, charge division readout etc.), transition radiation detectors etc.
(See Historical overview of main activities).

      At present the Tracking Detector Department participates in several international projects carried out in the leading world scientific centres: CMS and ATLAS (CERN, Switzerland), Moun-capture (PSI, Switzerland), SELEX (FNAL, USA), HERMES (DESY, Germany) and some others.
