Development of a solid state radiation hard high temperature sensor for neutron and gamma detection has many potentialuses. With long term reliability suitable for use in nuclear power generation plant, high energy physics, synchrotronfavilities, medical devices and national resiliience the use of solid state diamond devices is an obvious choice. Diamondeliminates the need to use helium-3 and is very radiation hard. Diamond is an expensive synthetic material and challengingto process reliably so work needs undertaking on the use of less expensive poly-crystalline diamond. Areas of innovationinclude precise laser cutting and plasma processing of diamond to improve the production of multi-layer devices for neutrondetection. Diamond polishing needs to be improved and understood so that optimal and economic devices can bemanufactured. Advanced electron micropscopy techniques, nano-mechanical and tensile testing, radiation testing as wellas high temperature neutron performance and mechanical stability will be demonstrated to show how this technology canbe applied successfully to future power plant designs and radiation monitoring.
