Construction of a scalable neutron source — •Eduard Friske — Universität Tübingen, Tübingen, Germany

The silicon strip detectors used in the Silicon Tracking System of the CBM project are expected to be subject to high doses of particles, including neutrons. To anticipate the effects of neutron irradiation of the detectors, a high rate neutron source is being constructed at the Rosenau accelerator facility. Using deuterium fusion and cooling via liquid nitrogen, this design will allow scaling of the neutron flux over a wide range of values. It also allows the online instrumentation of the sample during the irradiation process, as well as defined variations of the irradiation rate, e.g. to study annealing effects.
