Description
Ultracold Neutrons (UCN), neutrons with kinetic energies below 335
neV, provide a unique tool for fundamental neutron research with long
observation times.
The τSPECT experiment, which is currently being commissioned at
the pulsed UCN source of the TRIGA Mainz, aims to utilize this fact
in order to precisely measure the free neutron lifetime.
In order to reduce systematic errors with respect to previous storage
experiments using material bottles, τSPECT will implement 3D mag-
netic storage of spin polarized UCN and will be able to measure both
the decaying and the surviving UCN.
An introduction to UCN and their properties will be given as well
as a description of the τSPECT experiment and the planned neutron
lifetime measurements at the TRIGA Mainz.
