Working/Functional TitleHigh Power Targetry Staff Engineer

　　Position SummaryThe High Power Targetry Staff Engineer will support the establishment of various beam-intercepting devices in FRIB with a focus on the heat transfer engineering. Because those devices intercept high-power heavy ion beams, they suffer extreme heat load that other accelerator facilities have never experienced. To reach the ultimate goal of the 400 kW beam power, state-of-the-art heat transfer engineering is required to efficiently remove the heat deposited by the beams in the devices. The High Power Targetry Staff Engineer will lead the heat transfer engineering design and performance testing/validation of those advanced devices.

　　Major Duties/Responsibilities

　　Target and Beam Dump Systems (50%)

　　Lead the heat transfer engineering design and performance testing/validation of the advanced beam dump system to achieve efficient removal of the heat deposited by the primary beam.Support beam dump operations for user experiments. This includes technical support during normal working hours, on-call shifts at night, and over weekendsCollaborate with scientists who are knowledgeable in radiation damage of materials. Take into account that in the heat transfer design, the beam dump material property changes due to beam irradiation.Support other beam dump engineering design and performance testingCharge Selector (30%)

　　Lead the heat transfer engineering design and performance testing/validation of the high-power charge selector to achieve efficient removal of the heat deposited by the beam.Support charge selector operations for user experiments. This includes technical support during normal working hours, on-call shifts at night, and over weekendsCollaborate with scientists who are knowledgeable in radiation damage of materials. Take into account that in the heat transfer design, the charge selector material property changes due to beam irradiation.Support other charge selector engineering design and performance testingCharge Strippers (20%)

　　Support thermo-fluid dynamic analysis to understand the thermal response of the liquid lithium charge stripper thin film to high-power heavy ion beam irradiationSupport thermo-mechanical analysis to understand the thermal response of the rotating carbon foil stripper to high-power heavy ion beam irradiationSupport operations of charge strippers for user experiments. This includes technical support during normal working hours, on-call shifts at night, and over weekendsGeneral (occasional)

　　Work with stakeholders within the division as well as those outside of the division as necessary using clearly articulated (either verbal or written) communications to make sure smooth laboratory operationsCollaborate with scientists in world's leading heavy ion facilities to gain and apply the latest knowledge/discoveries to the FRIB's beam-intercepting devicesPublish papers in research journalsAttend conferences and workshops to share and exchange the latest knowledge with worldwide scientistsKnowledge, Skills, and Abilities

　　Through knowledge of fluid mechanics, thermodynamics and heat transfer theoryGeneral knowledge and ability to use SolidWorks and ANSYS (or other finite element methods as engineering calculation tools)Ability to communicate effectively and credibly, both verbally and in writing, with audiences at all management levelsAbility to accommodate shift work to support FRIB operationsAbility to problem-solve and demonstrate sound critical thinking skillsAbility to work independently, within a team, and in an extensive collaborationEqual Employment Opport
