Description

OCTOPUS and MANTA are DRD3 projects developing Monolithic CMOS pixel sensors suitable for full-silicon tracking at future e⁺e⁻ colliders. A key target of OCTOPUS is a spatial resolution of 3 μm for vertexing, while MANTA is a generic, configurable pixel sensor designed for a wide range of tracking applications. MANTA targets a slightly relaxed spatial resolution of below 10 μm and investigates the possibility of implementing time-of flight measurements with a precision below 100 ps for particle identification in the outer layers of the tracking system.

Both projects build on the 65 nm TPSCo process, allowing for shared design efforts. This presentation will outline the common features and challenges of the two sensors, describe the key features of their respective readout electronics architectures, and report on the current status of their simulation and design work.
