Within European Partitioning & Transmutation research programs, it becomes very important having the opportunity to use infrastructures specifically dedicated to the study of fundamental reactor physics of future fast neutron-based reactors. In this contest an Accelerator Driven System low power prototype, calls ISR Intrinsically Safe Reactor, was recently proposed and designed by the INFN Istituto Nazionale di Fisica Nucleare, in collaboration with Ansaldo Nucleare (Italy).
The ADS are systems that guarantee the production of nuclear energy thanks to the use of a fast subcritical core where fissions are maintained in a steady-state by supplying neutrons from an external source. The INFN proposal considers as external neutron source the 70 MeV, 0.75 mA proton cyclotron facility, already foreseen for the INFN SPES project at Laboratori Nazionali di Legnaro (LNL), Italy, and a Beryllium target as proton to neutron converter.
During the seminar I will discuss about my contributions to different topics related the project mentioned above, carried on during the two years fellowship spent at Laboratori Nazionali del Sud LNS of Catania. First of all, I will present the preliminary beam line design used to transport the 70 MeV proton beam, delivered by the SPES cyclotron, to the Be target, together with a description of the low power ISR facility. Optics design and magnetic elements arrangements, evaluated according to LNL building project, will be also discussed.
Moreover, I will describe my contribution to experimental tests conducted at LNS, devoted to the measurement of the neutron production yield from the Beryllium target. Due to the scarce amount of data in the energy region of interest, a dedicated and detailed yield measurement was performed at LNS, covering a large angular (from 0° to 150°) and energy range (from thermal up to beam energy). A description of the experimental technique adopted and the data results will be presented.
My contribution to the drafting of papers and my participations to international schools and conferences will be also mentioned.
