Description
In the past years, the instrument NECTAR has been rebuilt from the ground up with many upgrades for thermal neutrons. Continuing in these foot¬steps, NECTAR will further enhance its capabilities for H-quantification and phase mapping via energy-resolved neutron imaging. This will be achieved using a unique and compact chopper design. At its core, the chopper consists of a 100 mm diameter 3D printed boron-containing PLA insert that rotates around its cylindrical axis and contains an array of 684 channels, each measuring 1 × 1 mm².
Costs of a portable chopper less than 10,000 Euros (material, machining and electronics).
The talk is about the development of the Chopper, its problems of the prototypes and changes.
