Description

We report on new results and simulations 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 with ~1 ps resolution. Above ACE's energy threshold, a single 5 cm thick (1.4 $X_0$) layer of ACE waveguides would provide ~1 ps timing resolution, 3D spatial constraints on the scale of ~300 $\mu$m - 5 mm, and an additional energy measurement, making ACE a true 5D detector. When embedded inside another calorimeter technology, ACE timing layers could provide a powerful additional measurement for particle-flow reconstruction 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 proposed 100 TeV FCC-hh. We report on new simulation results from deploying ACE timing layers in the barrel and forward calorimeters at a future 100 TeV CoM collider and discuss ongoing research to further develop and improve the ACE detector concept.
