Abstract :
We present the new large neutron decay spectrometer Perkeo III designed to study neutron β -decay in-beam. It offers largely improved statistics over its predecessor Perkeo II. When used with a pulsed neutron beam, leading sources of systematic errors in other experiments are strongly suppressed or eliminated. The instrument was commissioned in a first run at the high flux reactor of the Institut Laue-Langevin, Grenoble. With a continuous polarized neutron beam, a neutron decay rate of 5 × 10 4 s - 1 was obtained.
