Becvár H. Beer J. Benlliure B. Berthier E. Berthomieux P. Baumann Física, Astronomía y Matemáticas A small-mass system has been developed for monitoring the flux of neutrons with energy up to 1 MeV at thenew time-of-flight facility at CERN, n TOF. The monitor is based on a thin Mylar foil with a 6Li deposit,placed in the neutron beam, and an array of Silicon detectors, placed outside the beam, for detecting the productsof the 6Li(n; ®)3H reaction. The small amount of material on the beam ensures a minimal perturbation of theflux and minimizes the background related to scattered neutrons. Moreover, a further reduction of the °-raybackground has been obtained by constructing the scattering chamber hosting the device in carbon fibre. Adetailed description of the flux monitor is here presented, together with the characteristics of the device, interms of efficiency, resolution and induced background. The use of the monitor in the measurement of neutroncapture cross-sections at n TOF is discussed 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434555 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.34 |
