A well-defined neutron spectrum is an essential tool for calibration and tests of spectrometry and dosimetry detectors, and evaluation methods for spectra processing. Many of the nowadays used neutron standards are based on a fission spectrum which has a smooth character. In recent time, at the LVR-15 research reactor in Rez, an alternative approach was tested for the needs of fast neutron spectrometry detector calibration. This process comprises detector tests in a neutron beam, filtered by one meter of single-crystalline silicon, which contains several significant peaks in the fast neutron energy range. Tests in such a kind of field can possibly reveal specific problems in the deconvolution matrix of the detection system, which may stay hidden in fields with a smooth character and can provide a tool for a proper energy calibration. Test with several stilbene scintillator crystals in two different beam configurations supplemented by Monte-Carlo transport calculation have been carried out. The results have shown a high level of agreement between the experimental data and simulation, proving thus the accuracy of the used deconvolution matrix. The chosen approach can, thus, provide a well-defined neutron reference field with a peak character for further tests of spectra evaluation methods and scintillation detector energy calibration.
