Description
The purpose of the retardation spectrometer aSPECT is to determine the antineutrino electron angular correlation coefficient 'a' with high precision, by measuring the integral proton spectrum in free neutron decay. A precise measurement of 'a' allows high precision tests of the Standard Model and physics beyond, i.e. the unitarity of the quark mixing CKM matrix, right handed currents, or scalar and tensor interactions.
Latest measurements with aSPECT were performed during April/ May 2008 at the Institut Laue-Langevin in Grenoble, France. The physical motivation and the design and optimization of the spectrometer as well as the status of the data analysis will be presented in this talk. I will close my speech with a discussion of possible further measurements.
