| Zusammenfassung | This paper describes a neutron monitor which consists of a spherical neutron moderator, 12″ in diameter, with a thermal neutron detector which detects delayed β-radiation from silver activation. The thermal neutron detector is based on four silicon diodes at the centre of the moderator, two of which are covered by silver foils, 250 μm thick, and two by tin foils, 360 μm thick. The latter two diodes are used to subtract the photon contribution. The system registers chiefly counts of β-rays from the 109Ag activation with a 25 s half-life. The performance of the neutron monitor in neutron and photon calibration fields is described by measurements and calculations. |
