Senior Mechanical Engineer, Cryogenics Group

Brookhaven National Laboratory • Upton, NY, United States • 3d ago

Brookhaven National Laboratory (BNL) is the building site for the Electron-Ion Collider (EIC), a one-of-a-kind nuclear physics research facility.  The EIC will be a discovery machine for unlocking the secrets of the “glue” that binds the building blocks of visible matter in the universe. The machine design is based on the existing and highly optimized RHIC Ion-Ion collider.   It will consist of two intersecting accelerators, one producing an intense beam of electrons, the other a beam of protons or heavier atomic nuclei which are steered into collisions.  Beyond sparking scientific discoveries in a new frontier of fundamental physics, the Electron-Ion Collider will trigger technological breakthroughs that have broad-ranging impact on human health and national challenges.

The Cryogenics Group is responsible for upgrading existing cryogenic systems, designing and installing new systems, and operations of these systems that will be part of the Electron-Ion Collider. The existing central plant and existing Hadron Storage Ring cryo-distribution system will be upgraded/renewed and re-used. New 2K satellite systems and new 2K distribution systems will be added to meet EIC requirements. The cryogenic system cools various superconducting magnets and various superconducting RF cavities throughout the EIC collider complex.
