Mechanical Engineer RF​/Cryo

The National Synchrotron Light Source II (NSLSII) is a state-of-the-art, medium-energy (3-billion-electron-volt, or GeV) electron storage ring that produces x-rays up to 10,000 times brighter than the original NSLS. The mission of the NSLSII is to provide extremely bright x-rays for basic and applied research in biology and medicine, materials and chemical sciences, geosciences and environmental sciences, and nanoscience. To support this program, the NSLSII must design, fabricate, assemble, test, install, and operate unique research equipment to generate, transport, transfer, accelerate and focus electron and X-ray beams.

This includes a combination of custom designed and built parts and vendor produced components developed by a collaboration of the NSLSII scientific, engineering, and technical staff. The NSLSII supports an international user community of over 2,200 researchers from 400 universities. The NSLSII performs all these functions in an environmentally responsible and safe manner, under a rigorous conduct of operations approach.

The NSLS-II RF Group designs, fabricates, operates, and maintains multiple high power Radio Frequency (RF) systems, including klystrons and solid-state amplifiers. The group also designs, assembles and operates normal conducting and superconducting RF cavities and a liquid‑helium cryogenic plant consisting of two 870-watt refrigerator/liquefier coldboxes. This position is responsible for the continued analysis, development, operation and optimization of mechanical components and sub‑systems for the RF cavities, transmitters, the cryogenic plant, and utility systems.

The successful candidate is expected to learn on the job all mechanical‑related RF and cryogenics concepts. You will work as a productive and collaborative member of a multidisciplinary team of engineers and technicians through all phases of system design, component selection, prototyping, fabrication, installation, commissioning, operation, and troubleshooting.
