- **Caution**: 

### Q: What are the primary materials used in rotating anode targets?
**A**: Rotating anode targets are primarily made from tungsten (W) or tungsten-rhenium (W-Re) alloys for the anode disc/target, with molybdenum (Mo) commonly used for the rotor and stem components to withstand high thermal and mechanical stress.

### Q: How does a rotating anode improve X-ray tube performance?
**A**: The rotating design distributes electron bombardment across a larger focal track area, reducing localized heat buildup and allowing higher power operation, longer tube life, and more stable X-ray output for precision manufacturing applications.

### Q: What industries use rotating anode X-ray tubes?
**A**: Computer, electronic and optical product manufacturing relies on rotating anode X-ray tubes for quality control, material analysis, semiconductor inspection, and non-destructive testing where high-resolution imaging is critical.
