The “Laboratoire National des Nucléides Cosmogéniques” (LN2C) at CEREGE is one of the leading institutions worldwide regarding the development of the cosmogenic nuclides systematics and applications. The leading position of CEREGE has recently been consolidated by an Accelerator Mass Spectrometry (AMS) facility (ASTER), inaugurated in 2006 (See Figure A1). LN2C also houses state-of-the-art laboratory facilities for the routine chemical sample preparation for 36Cl, 10Be and 26Al measurements, used for a large variety of applications in Earth Sciences.
