Los Alamos National Laboratory Experimental Low-Temperature Detector Post Baccalaureate Intern in Los Alamos, New Mexico

What You Will Do

We are seeking highly motivated and technically excellent recent graduates to join Los Alamos National Laboratory’s (LANL’s) Low-Temperature Detector (LTD) Research and Development (R&D;) team. Our focus is on the development of new sensors, systems, and analytical instruments for ultra-high precision x-ray and gamma-ray spectroscopy of radioactive and nuclear materials. The Low-Temperature Detector (LTD) Research and Development (R&D;) Team works on LTD-based systems for basic research, international nuclear safeguards, and national security. We are developing x-ray and gamma-ray spectrometers based on large arrays of transition-edge sensors (TESs) using microwave SQUID multiplexing readout and cryostat systems operated below 0.1 K.

Major goals include development and theory-validation of x-ray chemical analysis techniques and significantly increasing the technology readiness level of microcalorimeter-based measurement systems. This includes progressing from the current stage of development, physics experiments and engineering demonstrations, to the next level: complete analytical instruments that deliver calibrated spectra and spectral images to users. This is a very exciting time for the development and application of microcalorimeter-based technology, with major initiatives in gamma-ray spectroscopy, x-ray emission spectroscopy, and hyperspectral x-ray imaging (integration of large TES arrays with scanning electron microscopes).

Successful candidates will participate in one or more of the following areas:

  • Assist in the design, building, testing and use of innovative low-temperature-detector-based systems for ultra-high-resolution x-ray or gamma-ray spectroscopy.

  • Assist in prototyping analytical instruments based on TES microcalorimeter arrays with100-1000 pixels, microwave SQUID multiplexing, software-defined-radio readout, and low-latency data pipelines.

  • Assist in developing complete analytical instruments based on the integration of LTD arrays, microwave SQUID multiplexing, and scanning electron microscopes.

  • Develop or modify cryogenic systems optimized for low-temperature detectors.

  • Conduct spectroscopy campaigns using LTD-based systems as part of theory-validation of x-ray or gamma-ray spectroscopy techniques.

What You Need

Minimum Job Requirements:

  • Demonstrated experience showing initiative and follow-through in technical areas of responsibility.

  • Demonstrated experience working both independently and as part of team.

  • Demonstrated experience documenting and reporting on technical work, for example through written plans, proposals, reports, papers, articles, or theses.

  • Demonstrated experience showing excellent communication skills, written and oral, formal and informal.

Desired Skills:

  • Demonstrated experience conducting experimental R&D; in physical science or engineering.

  • Demonstrated experience developing, testing and using complex measurement systems or scientific instruments for physical science or engineering. This experience can be anywhere in the range from invention to prototyping to deployment.

  • Demonstrated experience with and understanding of ionizing radiation detection and measurement or hardware systems for operation at low temperature


  • Recent graduates (BS/BA Degree) would qualify for a 1-2 year appointment through our Post Baccalaureate program. To receive full consideration, candidates must have been awarded a bachelor’s degree in physical science or engineering.

  • All viable candidates must have a minimum GPA of 3.0/4.0 for consideration, and have earned the degree no more than 3 years ago.

  • A resume and current transcript, showing the above requirements, are required.

Additional Details:

No Clearance: Position does not require a security clearance. Selected candidates will be subject to drug testing and other pre-employment background checks.

New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing.
