Implication

Randomized trial demonstrates improved readout efficiency and radiation tolerance in a novel HV-CMOS sensor, indicating enhanced tracking in particle physics experiments.

Key Points

  • This work aims to introduce the MightyPix sensor and its capabilities for the LHCb Mighty-Tracker.
  • Developed MightyPix2 using AMS' aH18 process with a segmented matrix architecture.
  • Integrated enhanced readout and control systems with LHCb specific interfaces.
  • Simulated performance to analyze readout efficiency and radiation tolerance.
  • MightyPix2 achieved over 99.9% readout efficiency in simulations.
  • Sensor design supports hit rates exceeding 32 MHz cm$^{-2}$ with 3 ns timing precision.
  • Radiation tolerance tested with NIEL of 3 × 14 neq cm$^2$ and total ionizing dose of 40 Mrad.
