Sledovani zatěže konstrukcnich casti reaktorových systemů neutronovým zařenim je zasadnim parametrem dozimetrie reaktoru. Neutronove spektrum v konstrukcnich castech systemů lehkých vodnich reaktorů je modifikovano vodou a železem, zatimco

The absorption cross sections of low energy neutrons obey 1/v law for most materials. Therefore, the detection efficiency of a particular detector increase with decreasing neutron energy. Consequently, most of neutron measuring instruments consist of

Recently invented plastic scintillator EJ-299-33 enables pulse-shape discrimination (PSD) and thus measurement of neutron and photon spectra in mixed fields. In this work we compare the PSD properties of EJ-299-33 plastic and the well-known NE-213 li

We present a digital system for measurement of neutron spectra in mixed gamma-neutron fields. The signal from a standard scintillation detector is sampled at rate up to 1 GHz, using 12-bit analog-to-digital converters. First stage of the signal proce

A well-defined neutron spectrum is essential for many types of experimental topics and is also important for both calibration and testing of spectrometric and dosimetric detectors. Provided it is well described, such a spectrum can also be employed a

LR-0 reactor is an experimental reactor in NRI Rez, Czech Republic. So far an analogue apparatus was used for measurements of the space-energy distribution of the neutron gamma mixed field inside the reactor vessel. Recently we measured in LR-0 with
