Welcome to the Cabrera Group at Stanford University
There are a number of research programs in the Cabrera Lab. All use TES in different ways and for different goals. Short summaries follow and more information about each can be found in the links below or to the left. Enjoy!
- Optical Imaging TES array - Currently using a 32 pixel array, the Optical TES program uses small tungsten pixels to directly absorb photon energy. With intrinsic energy resolution (~0.2 eV at 2.33 eV or R ~ 11), time resolution of 1 microsecond and a high quantum efficiency, an imaging array of optical TESs is naturally suited to observe faint and/or rapidly varying sources such as pulsars. The optical program is a collaboration with Prof. Roger Romani.
- The Cryogenic Dark Matter Search - The CDMS group at Stanford is part of a larger collaboration looking for evidence of weakly-interacting massive particles, or WIMPS. The experiemnt uses TESs patterned on large germanium and silicon crystals to collect phonon energy from WIMP-nucleon recoil.
- Phonon-mediated X-ray TES and ATSSI - In collaboration with Lockheed Martin Solar and Astrophysics Lab, the X-ray project has several simultaneous research paths, all working together to use the TES as an X-ray detector to observe the solar corona from a sounding rocket platform. At Stanford, research is focusing on designing a distributed TES that would give high position resolution with a limited number of pixels. At Lockheed, research is focusing on overcoming the inherent difficulties of launching a cold TES and ADR (~50 mK) into space.
