Description

The Microtron MT 25 is a cyclic electron accelerator with a Kapitza type resonator. The accelerator is located in a laboratory belonging to the Nuclear Physics Institute of the CAS. The Microtron MT25 serves as a source of relativistic electrons (primary electron beam), secondary photon beams (bremsstrahlung) and neutrons from nuclear reactions. Photon beams are frequently used for instrumental photon activation analysis of geological, biological, environmental and others samples. This method allows non-destructive determination of number of elements not determinable by neutron activation analysis or determination some elements with a better sensitivity then INAA. The laboratory is equipped with coaxial HPGe detector and multichannel analyzer. In microtron laboratory was recently installed fully automatic pneumatic post for fast transport of samples between irradiation positions and HPGe detector. This system expands the possibilities of photon activation analysis, because it enables determination of samples with short half-life.
