Component Specifications

Definition
A collecting electrode is a critical component within an individual ionization chamber designed to attract and accumulate charged particles (ions or electrons) generated by ionizing radiation. It functions as the charge collection terminal, converting radiation-induced ionization into measurable electrical signals through precise electrostatic field control. This electrode maintains stable potential differences relative to other chamber elements to ensure efficient charge collection without recombination losses.
Working Principle
The collecting electrode operates on electrostatic attraction principles within an ionization chamber. When ionizing radiation interacts with the chamber's fill gas, it creates positive ions and free electrons. The electrode, maintained at a specific electrical potential (typically ground or biased voltage), attracts oppositely charged particles through the applied electric field. Collected charges generate a current proportional to radiation intensity, which is amplified and measured by associated electronics. The electrode's geometry and surface finish minimize field distortions and secondary electron emissions.
Materials
High-purity metals with low work function and excellent conductivity: Stainless steel (AISI 304/316), aluminum alloys (6061-T6), copper (OFHC), or gold-plated surfaces. Materials selected for radiation hardness, low outgassing, and corrosion resistance. Insulation typically uses ceramic (alumina) or high-performance polymers (PTFE, PEEK).
