Component Specifications

Definition
A high-voltage electrode is a critical component within an individual ionization chamber, designed to create and maintain a strong electric field between electrodes. This field ionizes gas molecules when radiation passes through the chamber, producing measurable electrical signals proportional to radiation intensity. The electrode operates at voltages typically ranging from 100V to 2000V, depending on chamber design and application requirements.
Working Principle
The high-voltage electrode applies a potential difference between electrodes within the ionization chamber. When ionizing radiation enters the chamber, it interacts with the gas, creating ion pairs. The electric field accelerates these ions toward the electrodes, generating a current that is measured to determine radiation levels. The electrode must maintain stable voltage to ensure consistent ionization and accurate detection.
Materials
Stainless steel (AISI 304/316), tungsten, or platinum-coated copper for corrosion resistance and high conductivity; ceramic or polymer insulators (e.g., PTFE, alumina) for electrical isolation.
