Los Alamos National Laboratory Experimental Low-Temperature Detector Engineer (R&D Engineer 2) in Los Alamos, New Mexico
What You Will Do_
We are seeking highly motivated and technically excellent engineers 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:
Design, build, test and use innovative low-temperature-detector-based systems for ultra-high-resolution x-ray or gamma-ray spectroscopy.
Develop prototype analytical instruments based on TES microcalorimeter arrays with 100-1000 pixels, microwave SQUID multiplexing, software-defined-radio readout, and low-latency data pipelines.
Develop or modify cryogenic systems optimized for low-temperature detectors.
Develop complete analytical instruments based on the integration of LTD arrays, microwave SQUID multiplexing, and scanning electron microscopes.
Conduct spectroscopy campaigns using LTD-based systems as part of theory-validation of x-ray or gamma-ray spectroscopy techniques.

Where You Will Work_
Located in northern New Mexico, Los Alamos National Laboratory (LANL) is a multidisciplinary research institution engaged in strategic science on behalf of national security. LANL enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.
NEN-1 works to safeguard nuclear materials by developing techniques and systems for nondestructive assay of nuclear and hazardous material. Applications include nuclear materials control and accountability for domestic DOE nuclear facilities, nuclear waste disposal, material stabilization efforts, and international nonproliferation efforts. NEN-1 instrumentation and analysis technology measures nuclear materials by detecting and analyzing the neutrons, gamma rays, or heat given off by nuclear material. NEN-1 instrument development begins with conceptual research and physics and proceeds through engineering to an industrial-quality, finished instrument.
