Analysis of the FIC detector data at the n_TOF facility

Fission cross-section measurements with the Fast Ionization Chamber (FIC) at the CERN n\_TOF facility were challenged by intense signals due to gamma-rays and ultra-relativistic particles from the impact of the 20 GeV proton pulses on the neutron spallation target. A method for analyzing the data ta...

description Fission cross-section measurements with the Fast Ionization Chamber (FIC) at the CERN n\_TOF facility were challenged by intense signals due to gamma-rays and ultra-relativistic particles from the impact of the 20 GeV proton pulses on the neutron spallation target. A method for analyzing the data taken with Flash Analog to Digital Converters (FADC) was developed to treat these problems in an automated way to provide a reliable background subtraction and a fit routine for identifying fission events even at high energies. The analysis is illustrated at the example of the fission cross-section of U-238 relative to that of U-235 in the energy range from 40 key to 300 MeV. (C) 2010 Elsevier B.V. All rights reserved.
