Description

C3DP is a software solution designed to create and optimize complex, non-traditional scattered beam collimators. Scattered beam collimators are critical for enhancing the sample signal-to-background ratio, particularly in experiments involving specialized sample environments like pressure cells or diamond anvil cells. These environments often generate significant background noise, making it challenging to identify the sample signal accurately.An optimized scattered beam collimator is essential to mitigate such background contributions. However, when the optimized collimator size exceeds the capabilities of additive manufacturing, C3DP provides an innovative approach by tailoring the collimator's shape to meet printing constraints while maintaining optimal performance.C3DP enables the simulation and optimization of uniquely shaped collimators for specific sample environments. It integrates instrument simulations with the special sample setup, extracting geometries that transition from neutron-simulated models to engineering CAD designs, ready for 3D printing. In this talk, we will demonstrate the features and capabilities of C3DP through practical examples, showcasing its role in advancing neutron scattering experiments for challenging sample environments.
