Description

We report on results from the Askaryan Calorimeter Experiment (ACE) which uses the coherent microwave Cherenkov emission from high energy particle showers in dielectric-loaded waveguides as calorimetric timing layers. Above ACE's energy threshold, a single 5 cm thick (1.4 $X_0$) layer of ACE waveguides would provide ~1 ps timing, 3D spatial constraints on the scale of ~300 $\mu$m to 5 mm, and an additional energy measurement, making ACE a true 5D detector. When embedded inside another calorimeter technology, ACE layers could provide a powerful measurement for particle-flow algorithms as well as unique vertexing capabilities to significantly reduce pileup. Due to thermal noise limits, ACE elements have a relatively high energy threshold so they are currently limited to future high CoM colliders like the FCC-hh. We report on new simulations from deploying ACE layers in the barrel and forward calorimeters at future colliders and discuss ongoing research to further develop the ACE concept.
