Detector Specialist (Research Technologist 3)

Job Description
Organization Name P-27/LANSCE Weapons Physics

What You Will Do


The Physics Division’s P-27 group includes research areas in the studies of nuclear reactions, nuclear structure, studies of the fission process, and nuclear astrophysics. The intense neutron spallation sources at LANSCE are used in much of this work and cover a neutron energy range from sub-thermal to 800 MeV.
A broad range of expertise and background is desired in the team, and there are multiple distinct projects that a successful candidate could pursue within the research disciplines of the team. There may be additional opportunities for collaborative work with scientists on the P-27 group or from other groups or divisions at LANL.
P-27 is looking for a detector specialist to work on direct and indirect measurements of neutron induced reactions. The successful candidate will assist P-27 scientists in performing experiments and developing the suite of instruments located at the Los Alamos Neutron Science Center (LANSCE). These instruments include the Detector for Advanced Neutron Capture Experiments (DANCE), the Low-Energy (n,z) (LENZ) instrument, the Time Projection Chamber (TPC), Chi-Nu and SPIDER. The selected candidate will be actively involved in developing new instruments to take advantage of the unique time-of-flight neutron beams available at LANSCE. Through the collaboration with the Isotope Production Facility (IPF) in LANL, we perform neutron-induced reaction measurements on radioactive nuclei at LANSCE. Outside Los Alamos, the group is actively pursuing measurements studying nuclear reactions in inverse kinematics.
