Detector Development

Detectors are a crucial part of neutron scattering instruments, responsible for measuring incoming neutron fluxes, as well as the positions and intensities of neutrons scattered by samples. Key performance aspects such as detection efficiency, time and spatial resolution, dead time, gamma sensitivity, and the ability to operate reliably under diverse environmental conditions are vital for ensuring instrument functionality, high-quality measurements, and ease of use. To meet the specific needs of different instruments, a wide range of established neutron detector technologies are employed.

Work on neutron detectors encompasses their development, commissioning, characterization, and maintenance, all aimed at ensuring high standards and reproducibility in measurements. The recent shortage of ³He gas, a key component in traditional detectors, has caused a significant price increase, prompting neutron centers to seek cost-effective alternative technologies. In response, the detector group at the Jülich Research Center has initiated the development of pixelated and high-resolution scintillation detectors. These alternative systems are designed to meet instrument requirements while enhancing performance and providing a more affordable solution.
