Essential training for understanding how gas detectors work, mastering total and coincidence counting methods, and being able to design and calibrate your own passive neutron measurement cell. ### Practical Information & Prequisites **Price:** €3975 excl. VAT per trainee **Location:** At Veolia | Nuclear Solutions offices in Aix-en-Provence **Duration:** 5 days (35 hours) **Prerequisites** - Reading, writing, understanding and speaking French - Module 1 or equivalent (understanding physical quantities such as activity, dose and the associated units) - Mathematical knowledge at A-level standard (logarithms, exponentials, solving equations with one unknown) ## Who is this course aimed at? Any staff who may be involved in the design of passive neutron measurement cells or in carrying out neutron counting measurements. Operators, technicians and nuclear measurement engineers. [Sign up](#contact) ### Learning objectives - Understand all neutron-matter interactions in order to comprehend neutron detection. - Identify and define the functions of all the modules that make up the passive neutron cell. - Apply the total counting method in passive neutron measurement. - Apply the coincidence counting method in passive neutron measurement. - Adjust the main electronic parameters of the neutron counting chain. ### Teaching methods and tools - Course materials and discussions with the trainer. - Tutorials and practical sessions. ### Assessment criteria Tutorials, practical sessions and a multiple-choice assessment at the end of the course. ### Detailed content - Neutron physics, neutron-matter interactions, moderation, and key reactions associated with detection. - Gas detector technologies: operating regions, ionisation chambers and proportional counters, advantages and disadvantages of 3He and BF3 detectors, sensitivities, wall effects. - Passive neutron measurements: total and coincidence counting, associated calculations, performance and limitations. - Implementation of a measured cell: specifying, designing and organising the testing of a measuring station. - Practical work: connecting the neutron measurement chain, setting the high operating voltage, setting the discrimination threshold, and performing passive neutron counting measurements.
