Definitions

  • the electrodes are electrically connected to supply means so as to define a succession of anodes and cathodes delimiting between them ionization chambers. These electrodes must preferably be of a sufficiently dense material to limit the crosstalk between the ionization chambers which they delimit. This is how many such multidetectors are fitted with tungsten electrodes. This material is very expensive and difficult to machine. The invention aims to solve these drawbacks.
