contactCopper foil is quite sturdy owing to its good mechanical strength. Its biggest advantage is the absence of resonance in thermal region. It behaves as a pure 1/ v -detector, all the way up to about 300 eV. The variation of activation cross section for 63 Cu (obtained from IRDFF-II library) is shown in Fig. 10.7.
