A physical justification of a correlation detector (CORD) system is present
ed. The results of CORD testing are described and its technical characteris
tics are presented. The detector comprises a three-layer array of scintilla
tion counters in the form of an elongated parallelepipeds whose cross-secti
ons are matched with the diameter of a multiplier phototube entrance window
. The total thickness of three layers is 15 cm, and the time resolution of
each layer is 0.2-0.3 ns. By measuring the energy deposited in the scintill
ators and the flight times of particles emitted from a target, it is possib
le to identify the particles and determine their energies. Measurements of
the time difference between the instants of light arrival to phototubes sit
uated on the scintillator ends allow the entrance coordinates of the partic
les to be determined with an accuracy of similar to 3.0 cm.
