57Fe Left: Count rate measured with a C 6 D 6 detector for a 0.1-mm Au sample, right: with a<br />
1.5-mm Fe sample. The raw neutron capture spectra obtained in the May/June campaign<br />
(black hi<strong>st</strong>ogram) are compared with the results obtained after the in<strong>st</strong>allation of the<br />
3.2 m iron wall in the secondary area. The simulation spectrum is also shown in the<br />
case of gold.
