Neutronic Detection
Neutron imaging is a non-destructive method used to see inside objects that may be inpenetrable by X-ray or other techniques.Neutrons offer the benefit of being able to see through heavy metals such as lead but can also be used to examine delicate processes.Photonis Neutron detector is designed to provide either still images or video using both cold and thermal neutron imaging techniquesfor non-destructive testing and neutron tomography.

Microwave Devices
Photonis Defense and its predecessors have been designing and manufacturing Traveling Wave Tubes (TWTs) since their invention in the early 1940’s. Photonis manufactures helix-type tubes that are constructed using the industry standard metal-ceramic construction. Our tubes are conduction cooled and feature rare earth periodic permanent magnets for power-free focusing.

Gamma Detectors
In Gamma detectors, the gamma radiations produce electrons by interacting with the cathode material and the filling gas.These electrons ionize the gas and the charge carriers are collected by the electrodes. The resulting anode pulse is detected by a load circuit. The primary electrons are created by several interaction mechanisms:- Photoelectric effect- Compton scattering- Pair production

Equipment & Vision Systems for Surveillance & Defense Applications
Photonis equipment systems are designed with Photonis sensors and cameras, while providing ease-of-use for in-depth image capture and analysis. These low light imaging systems are specifically developed with Night Vision, Observation & surveillance, Situation Awareness in mind.Two main equipments are proposed: the TacFusion is a handheld binocular combining low light camera core and thermal imaging sensor and the SR750 is a long range surveillance camera with powerful zoom and adapted ergonomics for rapid deployment. Both devices can be used for surveillance applications (police law-enforcement, borders and infrastructure surveillance) as well as SAR operations.

Neutron Detectors
As a neutron has no charge, a neutron detector incorporates a neutron-to-ionisation particle converter.The incident neutrons are captured by the converter material which then produces (detectable) ionising particles by means of a nuclear reaction.Photonis gas-filled detectors are designed to detect thermal neutrons (En < 0.025 eV), so the capture cross-section of the detecting material must be as large as possible for this low energy. We therefore use 235U (580 barn at 20 °C) for our fission chambers, and 10B (3840 barn at 20 °C) for our boron-lined proportional counters.

Mineral Insulated Connectors for Neutron & Gamma Detectors
The extreme operating conditions in which Photonis neutron and gamma detectors are operating can lead organic insulated cables to deteriorate, requiring repair. In order to have long lasting and reliable signal transmission Photonis offers high-immunity, mineral-insulated (MI) cable extensions and connectors. Our MI cable extensions allow transmission of low level impulse signals under harsh radiation and environmental conditions.Depending on the connector which is supplied with the detector, Photonis can provide either BNC, BNCHN or HN connectors. Photonis specific reinforced HN connectors can support up to 20 bar external pressure and remain tight at high temperature. Our cable extensions also provide efficient shielding to radiation and electromagnetic parasitic signals.

X-Ray Components
Photonis designed the Micro Pore Optics detector to be used in X-Ray imaging applications. Its perfectly square, flat channels are optimized to allow X-Ray and UV photons to be focused or collimated due to the total external reflection at a grazing angle (<2°). Micro Pore Optics are installed on a number of international space missions.
