Overview

Randomized trial explores hit detection efficiency in RD50-MPW4 detector, indicating high performance.

Key Points

  • The study aims to assess the performance characteristics of the RD50-MPW4 monolithic pixel sensor using TPA-TCT.
  • Analyzed RD50-MPW4 detector using Two Photon Absorption Transient Current Technique.
  • Measured depletion depth and charge sharing with micrometer-scale resolution.
  • Characterized the detector by illuminating it from the backside with a 1550 nm laser.
  • Achieved 100% hit detection efficiency under specified conditions.
  • Measured effective depletion depth of 226 μm.
  • Identified charge sharing at the boundaries of neighboring pixels.
