  1. A new detection concept formeasuring (n, g) crosssectionswithimprovedsensitivity and resolution C. Domingo-Pardo, C. Guerrero, J.L. Taín. (everybodyiswelcometojoin)

  2. A new detection concept formeasuring (n, g) crosssectionswithimprovedsensitivity and resolution • Motivation : the204Tl(n,g) case • Origin of backgroundwith C6D6TEDs • AnalternativeapproachforTEDswithimprovedpeak-to-background ratio • Preliminarysimulations • Conclusions & Outlook

  3. Motivation: measurements in largebackgroundconditions weaklevels (of interest) “contaminant” resonances Background level (couldbehigher at EAR2) • Themeasurement of smallsamples, lowCSsorweakresonancesischallengedbythepeak/background ratio, whichdependsbothonthe experimental conditions and onthedetectionsystemused.
