X-ray Tube

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard X-ray Tube used in the Computer, Electronic and Optical Product Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical X-ray Tube is characterized by the integration of Cathode Assembly (Filament) and Rotating Anode (Target). In industrial production environments, manufacturers listed on CNFX commonly emphasize Tungsten (Anode/Rotor) construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A vacuum tube that generates X-rays by accelerating electrons to strike a metal target.

Product Specifications

Technical details and manufacturing context for X-ray Tube

Definition
A critical component within a Radiation Therapy Simulator responsible for producing the X-ray beam used for imaging and localization. It enables precise targeting and verification of treatment areas by generating diagnostic-quality X-ray images that simulate the radiation therapy beam's path.
Working Principle
A cathode filament is heated to emit electrons via thermionic emission. These electrons are accelerated by a high voltage (typically tens to hundreds of kilovolts) towards a rotating anode (target). Upon striking the anode, the kinetic energy of the electrons is converted, with a small fraction (≈1%) into X-rays via bremsstrahlung and characteristic radiation, while the majority is dissipated as heat.
Common Materials
Tungsten (Anode/Rotor), Rhenium alloy (Anode target), Copper (Anode stem/heat sink), Glass or Ceramic (Envelope), Molybdenum (Cup/Support)
Technical Parameters
  • Maximum tube voltage, determining the maximum energy (penetrating power) of the produced X-ray photons. (kV) Standard Spec
Components / BOM
  • Cathode Assembly (Filament)
    Heats up to emit a cloud of electrons via thermionic emission when current is applied.
    Material: Tungsten wire
  • Rotating Anode (Target)
    Metal disc (often tungsten-rhenium alloy) that rotates to distribute heat; electrons strike it to produce X-rays.
    Material: Tungsten-Rhenium alloy on Molybdenum core
  • Glass or Metal-Ceramic Envelope
    Maintains a high vacuum to allow electron flow without collisions with gas molecules and provides electrical insulation.
    Material: Borosilicate glass or Aluminum oxide ceramic
  • Rotor/Stator Assembly
    Electromagnetic system that drives the high-speed rotation of the anode to dissipate heat.
    Material: Copper windings (stator), Steel alloy (rotor)
Engineering Reasoning
40-150 kV accelerating voltage, 0.1-1000 mA tube current, 0.1-10 kW power dissipation
Target temperature exceeding 2800°C (melting point of tungsten), vacuum pressure above 10^-4 Pa, anode heat load exceeding 300 kJ
Design Rationale: Thermal fatigue from cyclic heating/cooling (coefficient of thermal expansion mismatch), electron back-bombardment causing localized overheating, gas evolution from outgassing materials increasing pressure
Risk Mitigation (FMEA)
Trigger Exceeding 300 kJ anode heat load within 1 second
Mode: Tungsten target melting and vaporization
Strategy: Implementing rotating anode with molybdenum substrate (thermal conductivity 138 W/m·K), active oil cooling maintaining <60°C
Trigger Vacuum degradation to 10^-3 Pa due to outgassing
Mode: Gas ionization causing electrical arcing and filament oxidation
Strategy: Integrating non-evaporable getter pumps (SAES St707) maintaining 10^-6 Pa, using oxygen-free copper seals with 10^-9 Pa·m³/s leak rate
