Sensors Department

Sensors team

 

The Sensors Department has over a century of combined experience working in micro- and nano-fabrication clean rooms, with specific competencies in: Design, fabrication, and use of superconducting sensors and devices; High-density electronic interconnects and packaging; X-ray and particle detector system-integration, manufacture, assembly, and calibration; Semiconductor sensors and devices and micro-machining. The department works together with other TID departments and the Science Directorate in contributing to projects for cosmology, particle physics, neural science, medicine, accelerator diagnostics, and photon science. Furthermore, the Sensors Department develops TES spectrometers, soft x-ray cameras, and high-frame-rate detectors for LCLS-II first light and beyond.
