Abstract

Accelerated testing for neutron-induced SEE using spallation neutron sources is a well-established technique [1]. The best-known facility for this purpose is that at the Los Alamos Neutron Science Center (LANSCE) ICE House [2]. The VESUVIO instrument at the ISIS neutron source [3] is also available for such measurements, and results from this facility have begun to be published [4]. In this paper, we present the results of charge collection and SEU cross-section measurements made at ISIS, with comparison to equivalent results obtained at LANSCE. In so doing we characterise the VESUVIO beam for the purpose of SEE testing, using LANSCE as a benchmark. Charge collection statistics are used to determine LANSCE-equivalent flux [5] and the SEU behaviour of a static RAM-based FPGA is compared with previously published data from LANSCE [6]–[7][8].
