Simulation and design of individual neutron dosimeter and optimization of energy response using an array of semiconductor sensors

The performance of the simulation scheme has been compared with the commercial and laboratory samples in the world. Due to the deviation of all dosimeters with a flat energy response, in this paper, has been used an idea of one semi-conductor sensor to have the flat energy-response in the entire neutron energy range. Finally, by analyzing of the sensors data as arrays for the first time, we have reached a nearly flat and acceptable energy-response. | Simulation and design of individual neutron dosimeter and optimization of energy response using an array of semiconductor sensors Nuclear Engineering and Technology 51 (2019) 293e302 Contents lists available at ScienceDirect Nuclear Engineering and Technology journal homepage: www.elsevier.com/locate/net Original Article Simulation and design of individual neutron dosimeter and optimization of energy response using an array of semiconductor sensors R.
