Methods of neutron detection
Arbeit, Vít ; Števanka, Kamil (referee) ; Mičian, Peter (advisor)
This bachelor thesis deal with neutrons, ways to detect them and with neutron detectors themselves. The theoretical part includes description of all principles by which it is possible to detect them and defines both already established neutron detectors and the latest type of detector. The practical part is focused on realization of Bonner spheres and the measurement of their properties on a neutron source 241Am-Be.

The neutron flux characterization on the microtron MT25
Chvátil, David ; Králik, M. ; Granja, C. ; Krist, Pavel
Microtron is a small cyclic electron accelerator. When it is used as a source of neutrons, electrons must be converted to neutrons by means of nuclear reactions. Spectra of neutrons produced by high energy X-ray photons in lead and uranium targets installed on the microtron MT25 were measured by the Bonner sphere spectrometer with passive detectors of thermal neutrons. Neutron yield from uranium target was nearly two times higher than from the lead one.
