1 The Sense of Safety NEUTRON & GAMMA DETECTORS High Temperature for the toughest of requirements Sub-miniature Detectors for the closest range of measurement High Dynamic Range for the widest of flux variations

2 Safety Culture As a 1E, Safety critical, component supplier, PHOTONIS defines the sense of safety as its overriding priority. The Nuclear Instrumentation staff answers to a Quality Management program that uses both training and independent inspections. This QM program guarantees that you always get safety class components for your systems. The Nuclear Instrumentation team is organized according to ISO9001. Product and supporting documentation are delivered according to your nuclear manufacturing standards such as IAEA50-C-G / KTA1401, RCCE (EDF rules), ASME, HAF604.

3 Customised products Customisation, development & innovation Adapt versions of industrialised products to customer specific requirements. Develop new detectors with our experienced R&D team. Long term collaboration with the CEA (theoretical approach, modelling, qualification tests in research reactors). Full control of the complete manufacturing process on site. Support from all of the PHOTONIS Group activities, experience and knowledge. Tests and qualifications PHOTONIS products have passed qualification tests that guarantee reliable operation in many harsh environments. However, new detectors or environments may require additional testing. PHOTONIS is committed to implement this qualification work. Customer support activities Certifications & QA programs adapted to the customer environment Technical support, applying detector expertise Export control, as an Authorised Economic Operator, PHOTONIS acts in accordance with EU and International regulations Fissile material management & product storage
