Recently we observe a strong interest all over the world in compact neutron sources. This is triggered on one side by the demand to find a substitute for the closing fission reactor neutron sources, but also by the scalability of such a neutron source. Depending on science case and budget it is envisioned that such sources can be realized at universities to give an unprecedented easy and fast access to bread and butter instruments such as powder diffractometers and SANS instruments with immediate feedback into the ongoing research featuring then a rather low power, but also lower shielding constraints. On the other hand, accelerator driven neutron sources in the 100 kW power range will provide a source brightness that is comparable to nowadays medium flux sources.Despite the lower primary neutron production, the phase space provided by these sources at the moderator surface can adapted to the needs of a neutron scattering experiment with constrained and relaxed dimensions of the phase space depending on the demanded application. So the instrument can be optimized from source to detector and as such provides a highly specialized tool instead of an all-in-one device. We will discuss the conceptual instrument design based on the phase space arguments for different spectrometer types and continue from there to the optimization of a specific instrument with the help of simulation tools such as McStas or VITESS. |
