Description
The TESSERACT experiment will deploy 3 unique detector modules based on a common transition edge sensor-based readout to search for sub-GeV dark matter. HeRALD will use sensors with silicon or sapphire substrates to image radiative and quasiparticle emission from a target of superfluid helium-4 . SPICE will use sensors fabricated on sapphire and gallium arsenide substrates sensitive to both scintillation and heat signals produced by dark matter scattering within the substrates. Finally, a third module will use silicon or germanium substrates with applied electric fields and simultaneous charge readout. I will give an overview of the status of TESSERACT as we move toward deploying these modules for extended dark matter searches in Modane Underground Laboratory in 2028.
