Description
Precision 4D tracking, combining fine spatial resolution with picosecond-level timing, has emerged as an important direction for future collider detector systems. Over the past decade, substantial progress has been made in fast-timing sensors, advanced CMOS readout electronics, precision synchronization, and heterogeneous integration. The next challenge is to bring these developments together into scalable detector architectures and, ultimately, large-area tracking systems suitable for future experiments.
In this talk, we will discuss a path toward a coordinated U.S. effort in 4D tracking, building on complementary expertise across national laboratories and universities. As a concrete step in this direction, a new multi-institution program involving SLAC, Fermilab, LBNL, Caltech, and UCSC proposes to develop a four-plane 4D tracking telescope as a common system-level validation platform, together with next-generation timing ASIC architectures and advanced hybrid-bonding technologies. The telescope provides an environment in which sensors, electronics, synchronization, mechanics, reconstruction, and integration can be developed and evaluated together under realistic operating conditions.
Beyond the specific program, the goal is to explore how such a platform could evolve into a broader collaborative framework for U.S. 4D tracking R&D, enabling additional groups and technologies to contribute and establishing the foundations for the large-scale collaborative effort that will ultimately be required to realize 4D tracking for future collider experiments.
