Measuring the free neutron lifetime with τSPECT — •Noah Yazdandoost for the tauSPECT collaboration — Department of Chemistry, Johannes Gutenberg University, Mainz

The τSPECT experiment aims to measure the free neutron lifetime. Neutrons with energies in the range of nano electron-volts are loaded by spin flipping into τSPECT’s storage volume, where they are confined by magnetic fields only. Magnetic storage of the neutrons will reduce the systematic errors with respect to previous experiments with material confined neutrons since there is no interaction between stored neutrons and wall atoms. With the τSPECT experiment, the free neutron lifetime can be extracted by counting the surviving neutrons in the storage volume after different storage times. This talk gives an overview of the magnetic field configuration, the measurement process, and the data analysis strategies of the τSPECT experiment.
