Abstract
A new design for Small Angle Neutron Scattering instrument based on utilization of multi-pinhole collimator is presented. The 7-pinhole structure has been proposed for 30 years by Glinka[1]. But due to the crosstalk issue, the SNR is not as high as traditional single pinhole system. Luckily, software nowadays helps us to analyze the system and optimize the parameters of the collimator. With the help of 7-pinhole collimator instead of single-pinhole, we can approach almost one magnitude higher flux than before, which is valuable especially in compact pulsed neutron source, whose flux is a big issue.
