Main features
  • Structure: One coaxial mineral insulated cable connected to the detector.
  • Electrodes: The two electrodes consist of a concentric stainless steel tube assembly.
  • Filling gas: The gas type and pressure depend on the required sensitivity. Standard gases are nitrogen or xenon.
  • Insulators: As it is necessary to measure extremely low currents, insulators must be of very high quality and radiation resistant. Photonis only uses high-grade alumina insulators from qualified suppliers.
