The main focus of the project is to perform a comprehensive ray-tracing calculation, using e.g. the McStas software package, in order to design a tailored Ultra Small Angle Neuron Scattering (USANS) option for the SANS instrument LoKI at the new European Spallation Source ESS. LoKI is designed such to best use the characteristics of the ESS source for the study of complex systems in soft matter, biophysics, biochemistry and in materials science. At present approximately one experiment over 3 would profit from extending the Q-range using USANS, which is a strong motivation to implement USANS as an optional setup on Loki. Using the ray-tracing techniques (as MacStas) we want compare different approaches to achieve the USANS Q-range and choose the design best adapted for implementing USANS as an option on LoKI, taking especially into account that LoKI is a Time-of-Flight instrument. The main focus will lie on the required detector characteristics in order to have at least one additional order of magnitude in Q compared to LoKI´s standard Q-range.
Opus e' un progetto per disegnare e ottimizzare un'opzione di Ultra Small Angle Neutron SCattering per lo strumento LoKI presso la nuova sorgente di neutroni europea ESS in Lund.

Abstract
The main focus of the project is to perform a comprehensive ray-tracing calculation, using e.g. the McStas software package, in order to design a tailored Ultra Small Angle Neuron Scattering (USANS) option for the SANS instrument LoKI at the new European Spallation Source ESS. LoKI is designed such to best use the characteristics of the ESS source for the study of complex systems in soft matter, biophysics, biochemistry and in materials science. At present approximately one experiment over 3 would profit from extending the Q-range using USANS, which is a strong motivation to implement USANS as an optional setup on Loki. Using the ray-tracing techniques (as MacStas) we want compare different approaches to achieve the USANS Q-range and choose the design best adapted for implementing USANS as an option on LoKI, taking especially into account that LoKI is a Time-of-Flight instrument. The main focus will lie on the required detector characteristics in order to have at least one additional order of magnitude in Q compared to LoKI´s standard Q-range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
