Qualification of the Industrialized Libera MONACO 3 Digital Acquisition System dedicated to Fission/Ion Chamber Measurements in Research Reactors

Abstract

The CEA Sensor, Dosimetry and Instrumentation Laboratory (LDCI) has been working since 2011 on an integrated acquisition system called MONACO, ’Multichannel Online Neutron Acquisition in Campbell mOde’, for fission chamber measurements. Taking into account the feedback acquired up to the CEA TRL7 version, the LDCI Lab and the Instrumentation Technologies company (Solkan – Slovenia) initiated in 2020 a two years collaboration agreement to build the Libera MONACO 3 industrialized version required for reactor use and mass production. After a final qualification performed in the Slovenian TRIGA Mark II reactor in March 2023, the system will be available on the nuclear instrumentation market by the end of 2023.
