"If you think imaging neutron detectors are either bulky, slow or noisy, it's time to change your mind:
We offer a flexible single-event counting solution, based on neutron sensitive microchannel-plates with a large selection of active areas."
ADVANTAGES
Our demountable neutron detector product family is designed for scientists with the most demanding cold and thermal neutron imaging and timing applications. Highly user-friendly or “Plug-and-Play”, it comes as a complete turnkey neutron detection/imaging solution capable of extremely fast time-tagging of individual neutron events (~0.1 µs to 1 µs timing resolution) with excellent spatial resolution of ~50 µm or better. The system includes power supply, software, and firmware for displaying images in various data display configurations. There is nothing comparable available anywhere on the market for neutron researchers.

High Sensitivity of up to 80% for Ultracold Neutrons
PRINCIPLE OF OPERATION
TMTM
This combination allows complete flexibility in mounting the MCP neutron detector onto a vacuum chamber or evacuated neutron beamline. If preferred, an actively pumped detector with neutron-transparent front flange-mounted window for stand-alone operation can be provided.
Direct single neutron pulse counting operation is possible with the integrated Surface Concept delay line electronic readout, an exceptionally user-friendly readout allowing ~50 µm spatial and 100 ns (0.1 µs) timing resolution simultaneously – a unique and extremely powerful combination, unable to be matched by any other type of single unit neutron detector.

Based on the novel NeuViewTM Neutron Sensitive MCPs
Detection Principle: An impacting neutron produces charged particles by reacting with a 10B nucleus. This process releases electrons in the MCP, which in turn create secondary electrons that continue to multiply and create the output pulse.
