Abstract
The neutron flux and energy spectrum from the renewed cold neutron source was measured at the C2-1 beam port in the guide hall of JRR-3. We confirmed that both the absolute flux of 2×1012n/m2s and the shape of energy spectrum were reproduced after the replacement of the liquid hydrogen tank. JAEA has a plan to increase cold neutron flux ten times as strong as that at present by introducing a new type of hydrogen tank and super mirror neutron guide in the next term.
