APS Career Center

The primary responsibilities include conducting grant-specific scientific research, analyzing results, and reporting on findings, which may lead to further grant funding and opportunities for the NPRL. Supervise and train new students and employees on lab practices, techniques and equipment.

Job Responsibilities

- The primary responsibilities include work related to the design, development, and prototyping of integrated power supplies based on radioisotope batteries and photovoltaic power generation sources;
- Perform needs assessments and feasibility assessments, perform theoretical models/simulations, and prototyping for power supply systems to ensure the necessary components are utilized and the system can handle expected loads;
- Design and characterize wide bandgap photodiodes, Bragg reflectors, anti-reflective coatings, phosphor materials;
- Characterize photodiodes and phosphors, including optical (optoelectronic) characterization, structural characterization (x-ray diffraction), and radiation effects analyses;
- Determine minimum charging power specifics (current/voltage) for battery systems, and determine solar insolation for designated geographical regions;
- Design, fabricate, and characterize a rapidly deployable concentrator module which meets needs of customer, and integrate module with purchased solar cells and commercial off-the-shelf components;
- Assist with development of progress reports for research sponsors, prepare oral/poster presentations for scientific publication, prepare written manuscripts for journal publication, and deliver working prototypes of integrated power supplies;
- Additional duties as assigned.
