At the new research reactor FRM II in Garching near Munich the beam guide with the highest cold neutron flux is dedicated to Prompt Gamma‐ray Activation Analysis (PGAA) and related neutron capture experiments. We have designed a partially ballistic form of the neutron guide with the aim of concentrating the cold neutrons at the target position of the PGAA experiment. The cold neutron flux with a mean energy of only 1.83 meV was measured about 10.5 cm far from the second exit window and reached intensity of at a gold foil. The PGAA installation is now prepared for three different kinds of measurements—standard PGAA, Neutron Tomography of small samples and position sensitive PGAA, or PGAI for short. We have also measured coincidences in In this paper, we want to introduce the PGAA facility, show the diversity of the recently performed experiments and discuss further possibilities.
