The PARIS project — •Adam Maj — IFJ PAN Krakow, Poland

The measurement of high energy gamma rays with good energy resolution has always been experimentally challenging, with the best resolution obtainable from a scintillator detector being around 10% from sodium iodide. The novel scintillator material LaBr3(Ce) promises a step-change in what is achievable using scintillator detectors with an unprecedentedly high resolution of <3%. The PARIS array [1] is intended to comprise a double shell of this novel material and more conventional scintillator material. The array could be used in a stand-alone mode or in conjunction with an inner particle detection system (GASPARD, FAZIA), or with high-purity germanium arrays such as EXOGAM or AGATA. Initial designs and simulations for PARIS will be discussed as well as the potential Physics opportunities. The latter will focus on aspects such as the study of giant resonances, or of low- and intermediate-energy fragmentation and Coulomb excitations. The host laboratory for PARIS will be GANIL, nevertheless dedicated campaigns elsewhere (for example FAIR, RIKEN, Poland) are envisaged.
