Gravity modes are the best way to catch the internal dynamics of the radiative zone. These modes are difficult to detect for the Sun and hardly searched for with SoHO and the 3 seismic instruments. Candidates are now proposed (1) which are compatible with a non standard nuclear core. We present a new instrument, in construction with CNES agency which must improve by a factor 10 the performances of the previous generation of instruments and reduce substantially the solar noise. This small instrument could join the ILWS program.
