Description
We express interest to prepare a Time of Flight system to enhance the physics reach
of the FCC-ee detectors. The physics motivations are well established and we mostly
present here technical options considered and their possible implementations as ToF layers in the overall foreseen detector concepts. The performance target is to achieve a 30 ps MIP ToF precision with Monolithic CMOS sensor implementing at the same time
the position precision required to be part of a tracking systems. Such layers could also
be considered in a high granularity Si/W pre-shower calorimeter both to enhance the
calorimetry performance and the PID. The sensor R&D interests are outlined for two main technologies, with the prospect to simulate the performance of system configurations and to design the layer mechanical structures and services in a tracking configuration.
