The Raja Ramanna Centre for Advanced Technology (RRCAT) has successfully developed an indigenous Gifford-McMahon (GM) cryocooler capable of reaching a freezing −243°C (30 Kelvin).
With this breakthrough, India officially breaks into a highly exclusive club of nations possessing closed-loop cryogenic refrigeration technology.
Key highlights
• 🧩 Indigenous Helium Compressor: The team built the helium compressor entirely from scratch—the most critical and difficult part of the achievement.
• 🔥 The Engineering Challenge: Helium gas generates immense heat when compressed and leaks incredibly easily.
