Description

The OCTOPUS project addresses the development and characterization of monolithic active pixel sensors in the TPSCo 65 nm ISC technology in view of vertexing applications at a future lepton collider. Meeting the corresponding requirements -- outlined in the ECFA detector road map -- will necessitate the simulation, design, and testing of prototypes and a demonstrator chip in this very process.

In this context, we have reviewed literature on existing prototypes, with a focus on the results from test-beam characterization. For the OCTOPUS project, the presented results suggest the feasibility of the endeavor while showcasing challenges and the need for further investigations and provide a foundation for imminent design choices.

Performing such a literature review shows how difficult it is to compare test-beam measurements because of differences in methods and systematics. We will use this experience to make some suggestions on the definition of observables and selection criteria as a guideline for future test-beam analysis and the corresponding publications.
