  • If a thin layer of 10B is plated on the inside of the cathode surface, the detector can be used with a better proportional gas than BF3.
  • Less energy will be deposited in the gas compared to BF3, as either only the alpha or only the Li will be collected in one interaction.
  • It is this fact and the resultant spectral shape which suggests that such a detector will have a less clear cut discrimination with respect to the gammas than the BF3 detector, and a worse plateau.
