Description
The OCTOPUS project develops a monolithic pixel sensor in the 65 nm TPSCo process, targeting the vertex-detector layers at a future Lepton Collider.. A single-point resolution of 3 μm, a time resolution in the order of 5 ns, a hit-rate capability of up to 100 MHz/cm², maximal thickness of 50 μm, an average power consumption below 50 mW/cm² are required. Additionally a minimal inactive periphery area and a sensor architecture scalable to a large-area detector system are targeted. To achieve this, detailed simulations based on generic doping profiles are used to optimise the sensor layout and novel readout schemes are developed to process the high data rates with minimal power budget.
The first project stage aims at developing a high-resolution sensors for beam telescopes at DESY and CERN, with relaxed power-consumption (<500 mW/cm²) and timing requirements (100 ns).
The contribution will introduce the project and specifications, present the current status of the chip design and future plans. Additionally, simulation results optimising the sensor geometry will be highlighted.
