The described system is designed for automatic activation analysis with 14 MeV neutrons. The automatization comprises all operations and time control of the activation cycle. There is a possibility of independent programming of the irradiation time, the decay timè and seven consecutive measuring periods in large range (3 sec to 80 min) by means of a special time control unit. The dispatch of containers with samples is done with a very simple pneumatic device. The design and effectivity of shieldings against fast neutrons are also described.
