Abstract.

We shall discuss about the scientific motivation and construction of a 7 x 7 BaF₂ crystal array at Variable Energy Cyclotron Centre, Calcutta. This detector would be used to measure high energy g -ray photons from GDR decay and proton--neutron bremsstrahlung reactions at the present 88'' cyclotron and upcoming superconducting cyclotron at VECC, Calcutta. This detector can also be used to measure photons from quark--gluon plasma at the relativistic heavy ion collider (RHIC) in USA.

Keywords:  BaF₂ crystal; fast signal; slow signal.
