Description
The Nuclear Physics Institute of the Czech Academy of Sciences operates several fast neutron generators. The generators are based on the reaction of accelerated protons (U120M cyclotron, energy of protons up to 35 MeV) with the lithium and beryllium targets. The produced quasi-monoenergetic and continuous neutron spectra with energies up to 33 MeV have been well characterized.
The neutron beams are shaped using a 160 cm long polyethylene/iron collimator with the 3 cm diameter. The array of NE213 scintillation detectors operating in the Time-Of-Flight mode is used to measure the neutrons scattered in the sample placed in the collimated neutron beam.
The obtained data are used for the validation of the nuclear data evaluations. In this work, the results of first irradiation with the carbon reference sample are presented.
