Cryocollimator for Accelerators

Cryocollimator for Accelerators


The cryocollimator is a highly precise special component developed for the FAIR accelerator at GSI in Darmstadt. It optimizes high-energy particle beams by capturing and containing unwanted particles under cryogenic conditions (down to 4 K). As a globally unique prototype, the cryocollimator was specifically developed for FAIR. Its construction from high-purity copper and stainless steel ensures thermal efficiency, mechanical stability, and vacuum compatibility – even under extreme radiation and thermal conditions.

Applications

Optimization and control of beams in particle accelerators

Used in superconducting experiments, material science, and nuclear physics

Demonstration of innovative beam control technologies at low temperatures

Key Features

  • Uniqueness: Custom-developed prototype with iterative optimization
  • Material Selection: High-purity copper for heat transfer, stainless steel for mechanical strength
  • Joining Technologies: Vacuum brazing, TIG and laser welding, explosion-bonded copper-stainless steel joints
  • Thermal Stability: Special design for centering and stress reduction at 4K
  • UHV Leak Tightness: Low-outgassing materials, helium leak testing, and vacuum-suitable design
  • Integration: Seamless integration into FAIR infrastructure (cooling and beam guidance systems)
  • Quality Control: Non-destructive testing to ensure dimensional accuracy and surface quality

The cryocollimator for FAIR represents a technological milestone in cryogenic particle physics. It combines state-of-the-art joining technologies, custom material combinations, and the highest thermal and mechanical stability.

As a one-of-a-kind prototype, it demonstrates how close collaboration, innovative spirit, and engineering precision can lead to groundbreaking research solutions.
