✦ Synopsis

We present the new large neutron decay spectrometer PERKEO III designed to study neutron b-decay inbeam. 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 Â 10 4 s À1 was obtained.
