About

Nader Jamshidi is a leading engineer and innovator in accelerator vacuum technology, whose work has been critical to the performance of the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. His primary research focuses on the development of robotic plasma deposition systems for the *in-situ* coating of long, small-diameter vacuum tubes. Jamshidi’s major contributions address two critical problems in high-energy accelerators: the suppression of performance-limiting electron clouds and the mitigation of unacceptable ohmic heating in stainless steel beam pipes. He designed and fabricated a pioneering robotic "magnetron mole" capable of depositing thick, oxygen-free high-conductivity copper (OFHC) coatings inside the RHIC cold bore tubes. This technique, detailed in his most-cited works (each garnering 3–4 citations), provides a low secondary electron yield (SEY) surface that effectively suppresses electron clouds while reducing resistive heating. His work is notable for solving a unique engineering challenge—operating a plasma sputtering device in a constrained, cryogenic environment—and has directly enabled future upgrades to the RHIC machine. Jamshidi’s innovative approach to *in-situ* coating remains a benchmark for vacuum system maintenance in particle accelerators worldwide.
