The development of the process of electrophoresis deposition of the boron on aluminium substrate to be used in the construction of neutron detectors
Description
The development in the country of autonomous nuclear technology made it necessary to construct radiation detectors to substitute the imported ones among others the boron lined neutron detectors. For this reason was developed the process of boron electrophoresis deposition on aluminium substrate of large area for use in the construction of these neutron detectors. After the definition and optimization of the parameters involved in the process, depositions of 10B were made on cylinders to be used after wards as electrodes in gamma compensated and non-compensated ionization chambers and in proportional detectors. Prototype of ionization were designed, builted and mounted in the department of Application for Engineering and Industry (TE) of Nuclear Energy Research Institute (IPEN) belonging to the National Atomic Energy Comission (CNEN). Submited to caracterization tests at IPEN's IEA-RL reactor, they satisfied fully the technical especifications of the project. (author)

O desenvolvimento da tecnologia nuclear autonoma no pais tornou necessaria a construcao de detectores de radiacao nacionais para substituir os detectores importados, dentre os quais os detectores de neutrons com deposito de boro. Por esta razao, desenvolveu-se o processo de reposicao eletroforetica de boro em substratos de aluminio, de grandes superficies, destinados a construcao de detectores de neutrons. Apos a definicao e otimizacao dos parametros do processo, realizarem-se deposicoes de 10B em cilindros que foram utilizados como eletrodos em cameras de ionizacao compensada e nao compensada a radiacao gama e em detectores proporcionais. Os prototipos das camaras de ionizacao foram projetados, construidos e montados no departamento de Aplicacao na Engenharia e Industria (TE) do IPEN e submetidos a testes de caracterizacao no reator IEA-RL e atenderam satisfatoriamente as especificacoes tecnicas do projeto.
