Description
A high Light Yield Liquid Argon chamber has been radiated with an AmBe source to test the possible separation signal-to-background obtainable in a Dark Matter Liquid Argon based detector.
Apart from the standard nuclear recoil and electron events, from neutron elastic interactions and gamma conversions respectively, an intermediate population has been observed which is attributed to inelastic neutron scatters on Argon nuclei.
Taking account of these events results in determining the recoil-like to electron-like primary pulse shape separation.
The results of this recent study as well as from a previous study with a chamber with a lower Light Yield will be presented.
