The G1 cave hosts the VAMOS spectrometer.
VAMOS (VAriable MOde Spectrometer) is a large solid angle ray-tracing spectrometer employing numerical methods for reconstructing the particle trajectory. Complete identification of reaction products has been achieved by trajectory reconstruction. Equiped with a versatile detection system, VAMOS is capable of identifying reaction products from diverse reactions using beams at GANIL. The angular acceptance of the spectrometer reaches 80 mstrd, while the Brho acceptance +/- 25%.
The spectrometer is often coupled to high efficiency gamma ray detection array like AGATA or EXOGAM.
