The PARIS calorimeter project, being realized in the international collaboration coordinated by IFJ PAN, aims at constructing of a large detector array of novel phoswich scintillators for measuring gamma-rays over a wide range of energy. It is envisaged to serve the dual purpose of a high energy gamma-ray spectrometer (or calorimeter) and a spin-spectrometer, capable of determining the multiplicity of low energy discrete γ rays associated with a specific reaction. Upon completion PARIS is designed to be an array of 216 phoswich detectors covering close to 4π solid angle.

A variety of interesting experiments in nuclear structure and reaction dynamics are foreseen to be pursued with PARIS using both stable and radioactive ion beams. The first experiments with few PARIS clusters were performed at IPN Orsay, GANIL and in IFJ PAN Kraków.

In the talk the main idea of PARIS gamma calorimeter will be described and the information about PARIS status and performance during the first experiments will be given. In addition, the perspectives for physics cases to be studied with PARIS will be discussed.
