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.

"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."

Andreas Oelsner, CEO Surface Concept GmbH

Plug-and-Play Convenience

Large Active Areas up to 150mm

Based on the novel NeuViewTM Neutron Sensitive MCPs

High Sensitivity of up to 80% for Ultracold Neutrons

Neutron Sensitive Delay Line Detector with 40 mm active area

PRINCIPLE OF OPERATION

Surface Concept’s new open face detector, enabled by NOVA Scientific’s unique neutron-sensitive NeuViewTM MCPs is now available in a wide range of formats up to 150mm. These highly user-friendly and ‘turnkey‘ delayline readout systems are capable of very high spatial and ultra-fast timing resolution. NeuViewTM MCPs represent a patented technique of NOVA Scientific Inc.

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.

Operation Principle of NeuViewTM Neutron Sensitive MCPs

Neutron

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.
