A 2D X-ray diffractometer requires strict daily maintenance to ensure accuracy. Key tasks include managing the operating environment (temperature 15–25°C, humidity 20–80%, dust and vibration-free). Regular cleaning of the sample holder and internal components is essential, alongside maintaining the recirculating cooling water system to prevent blockages. X-ray tubes need proper conditioning after extended inactivity and must be set to standby or shut down appropriately. The computer workstation requires data backup, and strict safety precautions, such as avoiding contact with beryllium windows and never bypassing safety interlocks, are critical.
