Title Development of high energy neutron counters for the ChipIr beam line at ISIS-TS2
Contributors
Abstract The measurements of the so-called Single Event Effects (SEE) are becoming of great importance to assess the robustness of integrated circuits featuring dimensions of tens of nanometers. SEEs occur when a highly energetic particle (e.g. a neutron present in the environment) causes a disruption of the correct operation of an electronic component by striking its sensitive regions. Commercial-off-the-shelf devices are becoming popular in mission- or safety-critical applications, since they satisfy the designers’ need for high performance computing at moderate prices. However, to exploit such devices, fault-tolerant design techniques must be employed, and extensive analyses are needed to qualify their robustness. Experiments with atmospheric neutrons at different altitudes can be carried out but, due to the low intensity, they require very long periods of data acquisition. Neutron sources represent an opportunity due to the availability of high-intensity fluxes which allow accelerated irradiation experiments. Recent experiments performed at ISIS on the VESUVIO spectrometer to measure SEE rate in chips of different technologies demonstrated the suitability of the ISIS source for this kind of application. The PANAREA project aims at the design and construction of a dedicated beam line for chip irradiation: the ChipIr instrument. A very important task for ChipIr design is the development of suitable and effective neutron beam monitors capable of locally measuring the neutron fluence in the energy region above 1 MeV up to 800 MeV. In this contribution, we will present the first test results obtained with Bonner Spheres and Single Crystal Diamond detectors.
