This study introduces the structure,type,and principles of the emitter of a self-powered neutron detector.The emitter materials are classified based on their reaction principles,and the characteristics and mechanisms of each kind of material are thoroughly explained.Analyzed data on the physical properties,reaction processes,and sensitivity data of rhodium,silver,vanadium,cobalt,hafnium,platinum,molybdenum,beryllium,and other materials were presented.Combined with literature data,the study presents an analysis of the future applications of several new emitter materials.The results indicate that iridium and tantalum are fast-responding emitter materials with highly sensitive characteristics and might be promising for future applications.Beryllium was also found to be efficient in measuring fast neutrons.
