Descripción

ANNIE is a 26 ton Gd-loaded water Cherenkov detector installed in the Booster Neutrino Beam at Fermilab. It will measure the neutron multiplicity, as a function of momentum transfer, of neutrino-neutron interactions on water. To achieve this, it is imperative that the neutron capture characteristics in the detector volume are well parameterised. This talk will introduce the Americium Beryllium calibration source, highlight its successful deployment, and present the resulting neutron detection efficiency map and measured neutron capture time.
