MightyPix - a novel HV-CMOS sensor for the LHCb Mighty-Tracker
MightyPix is a High Voltage Monolithic Active Pixel Sensor (HVMAPS) for the proposed LHCb Mighty-Tracker. It is designed to handle hit rates of over 32 MHz cm(-2) with 3 ns timing precision and a high radiation tolerance with NIEL of 3 x 10(14) neq/cm2 and 40 Mrad total ionising dose. Building on pr...

| Summary: | MightyPix is a High Voltage Monolithic Active Pixel Sensor (HVMAPS) for the proposed LHCb Mighty-Tracker. It is designed to handle hit rates of over 32 MHz cm(-2) with 3 ns timing precision and a high radiation tolerance with NIEL of 3 x 10(14) neq/cm2 and 40 Mrad total ionising dose. Building on prior prototypes, MightyPix1 and LF-MightyPix, MightyPix2 integrates a segmented matrix architecture with enhanced readout and control systems, including LHCb specific Timing and Fast Control (TFC) and Experiment Control System (ECS) interfaces, a synthesized double data rate (DDR) serializer, and an improved column-drain architecture with hit preloading. Designed in AMS' aH18 process, MightyPix2 achieves over 99.9 % readout efficiency in simulations and supports serial powering. |
