What is VAMOS ?

VAMOS (VAriable MOde 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.
  Equipped 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 the high efficiency EXOGAM  array to obtain recoil coincidences for studying nuclei far from stability.
