Mechanical Engineering, Electron-Ion Collider
Mr. Holmes is the Mechanical Engineering Group Leader within the Technical Systems Division for EIC. He joined the Collider-Accelerator Division in February 2017 with over 20 years of experience in the design of particle accelerator systems and components.
Mr. Holmes has 35 years engineering experience with 25 years of that time dedicated to particle accelerator engineering design. He started his career working in the Advanced Energy Group of Northrop Grumman where he led various efforts to design and manufacture ion accelerator components and test cavities including a Radio Frequency Quadrupole (RFQ), and a Drift Tube Linear (DTL) accelerator as well as the RF power coupler for these cavities used on Northrop Grumman’s Ion Source Test Stand. More recently he worked at Advanced Energy Systems Inc. (AES) where he was responsible for the mechanical design and fabrication of many superconducting RF cavities and cryomodules for use at BNL, JLab and FRIB. This includes the BNL 704 MHz SRF gun/cryomodule, BNL 5-cell eCx ERL cavity/cryomodule, BNL-3 704 MHz 5-cell SRF cavity, JLab 2.25 GHz 3rd harmonic SRF injector cavity and the FRIB Beta 0.041 quarter wave SRF cavities. After his work at AES, Doug took on the role as Beamline Engineer at NSLS-II while working for the New York Structural Biology Center who is partnered with NSLS-II for the design, installation and operation of the NYX Beamline (Beamline ID-19).
