Abstract

PENeLOPE is a new high-precision experiment on the neutron lifetime τ_n planned at the Physik Department of Technische Universität München. Contrary to most lifetime experiments with stored neutrons so far, ultra-cold neutrons (UCN) are contained in a magnetic multipole field created by superconducting coils. The UCN are gravitationally bound in vertical direction, which allows extraction of the decay protons onto a detector. Using these techniques a precision of Δ τ_n < 0.1 s is aimed for. An updated experimental setup of PENeLOPE is presented, simulations and expected systematic effects are discussed.
