Anode Target: Focal Spot Size 0.1-2.0 mm

Component Specifications

Definition

The anode target is a critical component in an X-ray source tube where high-energy electrons from the cathode strike its surface, producing X-rays through bremsstrahlung and characteristic radiation. It's typically made of high-atomic-number materials like tungsten or molybdenum to maximize X-ray production efficiency and heat dissipation.

Working Principle

When high-voltage is applied between cathode and anode, electrons accelerate toward the anode target. Upon impact, their kinetic energy converts to X-rays (bremsstrahlung) and characteristic radiation, while generating significant heat that requires efficient cooling systems.

Materials

Tungsten (W), Molybdenum (Mo), or Tungsten-Rhenium (W-Re) alloys; sometimes with copper or graphite backing for heat dissipation

Frequently Asked Questions

Why is tungsten commonly used for anode targets?

Tungsten has high atomic number (74) for efficient X-ray production, high melting point (3422°C) to withstand electron bombardment, and good thermal conductivity for heat dissipation.

What is the difference between stationary and rotating anode targets?

Stationary anodes have fixed targets for lower-power applications, while rotating anodes spin to distribute heat over larger surface area, allowing higher power and longer tube life.
