Abstract
While designed primarily for X-ray imaging applications, the Medipix3 ASIC can also be used for charged-particle tracking. In this work, results from a beam test at the CERN SPS with irradiated and non-irradiated sensors are presented and shown to be in agreement with simulation, demonstrating the suitability of the Medipix3 ASIC as a tool for characterising pixel sensors.
Highlights
Neutrino is probably one of the most enigmatic and at the same time the most wide-spread particles in the Universe [1]
The most intensive laboratory neutrino source is provided by nuclear fission – for instance, a typical Russian 3 GWth industrial reactor WWER-1000 produces about 1021 antineutrinos per second
Additional uncertainty is caused by variation of the fuel composition within the reactor life-time: initial active 235U isotope burns out intensively, whereas so-called “weapon” 239Pu is produced from a ballast 238U which represents about 88% of the fuel mass 5
Summary
Neutrino is probably one of the most enigmatic and at the same time the most wide-spread particles in the Universe [1]. In addition to numerous equipment, thick walls of heavy concrete and the reactor body with more than 70 tons of uranium, there are several huge reservoirs with technological liquids placed above the room – repository of the primary coolant and boric acid for the reactivity adjustment, as well as a cooling pond for the spent fuel. These hydrogen-containing materials completely remove fast cosmic neutrons which are the main source of background in such measurements (see Section 4 below). The latter one was chosen, because it provides enough space for big dimension equipment
