Abstract
We present the new guide design for the reflectometer AMOR at SINQ optimized for high intensity on the sample (gain factor 10) and reduced background. The design uses wavelengths longer than 3.5 Å and homogeneously illuminates horizontal samples with a 30 mm x 10 mm cross section. It allows for short counting times due to simultaneous measurement of Δθ = 1.5° in the specular regime. The beam transport relies on Selene guides using point-to-point focusing. We describe the application of this geometry to the conditions at SINQ including a focusing antitrumpet for transport to the virtual source. McStas simulations show a high performance of the new design. Shielding design has been checked with MCNP simulations.
