- look for collective flow of photons and charged particles (like pions and protons)
- to estimate the percentage of the elliptic flow depending upon the centrality
The PMD is a Pre-shower photon Detector suitable for counting photons in high-energy nucleus - nucleus collisions.
The honeycomb chambers are fabricated in the form of unit modules, which can be handled conveniently.
The unit module consists of a rhombus of side approx. 260 mm containing a matrix of 24 x 24 cells.
This shape has identical boundaries on all four sides. The wall thickness at the boundaries is half of that of the inner walls.
The control system consist of three distinct subsystems:
