Alexandre Sitnikov

Cryogenic Engineer, Mechanical Engineering Group, NSLS-II Accelerator Systems Division

Prior to joining NSLS-II, Alex worked at the Canadian Light Source (CLS) in Saskatoon, Canada. At the CLS, he was responsible for managing all engineering aspects during design and bid reviews of components, such as vacuum vessels with the pumping systems, precision optical devices, diagnostics, electromagnets water and electrical services with elements of control systems.

Alex attained his MS degree in Mechanical Engineering from Novosibirsk State Technical University, Russia and was immediately employed as a mechanical design engineer by the Budker Institute of Nuclear Physics in Novosibirsk.

Reporting directly to Sushil Sharma, Alex’s responsibilities will include leading the cryogenic engineering effort for the superconducting RF cryogenic system of NSLS-II. This system will consist of a 900W helium refrigerator/liquefier and a 3000 liter dewar feeding up to six RF cavity cryostats, along with associated valve boxes, transfer lines and helium recovery systems.
