The TESSERACT Collaboration is developing two experiments, SPICE and HeRALD, to search to low mass particle dark matter. TESSERACT stands for Transition Edge Sensors with Sub-EV Resolution And Cryogenic Targets. The TES sensors used are common to both SPICE and HeRALD, which used different target materials and are sensitive to different DM models. The Tesseract geometrical shape, pictured in the logo, is also evocative of the background shielding strategy using nested shields.
