The neutron time-of-flight facility n-TOF at CERN: Phase II
(AIP Publishing, 2011)
Neutron-induced reactions are studied at the neutron time-of-flight facility n-TOF at CERN. The facility uses 6∼ns wide pulses of 20 GeV/c protons impinging on a lead spallation target. The large neutron energy range and ...
