After installation, the work can be started. The CT tube is actually a large high-vacuum cathode. The ray diode is a system that generates x-rays. Its working process is as follows: the 12V current is supplied to the cathode filament for heating, and free electrons are gathered. At this time, when 40-150kV high-voltage electricity is applied to the cathode and anode, the potential difference increases sharply. Driven by a strong electric field, the free electron beam in an active state hits the anode molybdenum-based tungsten target at a high speed by the cathode, and energy conversion occurs.
