Characterization of low output portable neutron generators operated at FNSPE CTU in Prague

Original language description

Low output portable DD and DT neutron generators are used at Faculty of Nuclear Sciences and Physical Engineering of the Czech Technical University in Prague for variety of research and educational applications. The paper summarizes some acquired experience related to characterization of these devices. Specifically, it includes determination of the total neutron generator emission, dependence of neutron emission on operational parameters, and characterization of pulsed mode operation. Whereas for ca. 1E8 n/s DT neutron generator, the total neutron generator emission has been estimated via foil activation technique, for 7E6 DD neutron generator the manganese bath technique has been applied. Further, the pulsed mode operation has been analysed over wide range of frequencies utilizing in-house developed set-up based on Red Pitaya Stem-lab. The verification of the set-up for the purpose is provided as well as the discussion of using epithermal (cadmium covered thermal neutron gas-filled detector) and fast neutron detector (of diamond type) for the purpose. Finally, the discussion is provided on measurement of neutron output dependence on operational parameters, as well as on self-activation of the devices and characteristic X-ray produced during their operation.
