Systematic Uncertainty due to Energy Reconstruction and Scattering in Beta Asymmetry Experiments

An analysis of sources of systematic uncertainty associated with conventional beta asymmetry experiments such as UCNA and PERKO III will be presented, focusing on effects associated with beta energy reconstruction and scattering. The impact of conventional calibration strategies using conversion line sources, sensitivity to hardware energy thresholds and some aspects of scattering will be analyzed, focusing on strategies for reducing systematic uncertainty in next generation experiments. Some aspects of the impact of energy reconstruction uncertainties on the sensitivity to Fierz terms will also be presented.
