Event Details

Experiments seeking to detect rare event interactions such as dark matter or Coherent Elastic Neutrino Nucleus Scattering (CENNS) are striving for large mass detectors with very low detection threshold. After a brief review of the dark matter and CENNS searches and the interest in low threshold and large mass detectors, I’ll discuss possible detector alternatives using a thermal phonon low temperature readout in semiconductor substrates. I’ll present latest results from one of our detectors that has led to world best resolution of <7 eV and our path toward single electron resolution detectors.
