Strategic Insights

— 2 min read

Current research into the development of Monolithic Active Pixel Sensors (MAPS) has led to significant breakthroughs in particle physics, particularly in the design of future lepton colliders and beam telescopes. The TANGERINE project, supported by the Helmholtz Innovation Pool Project and the CERN EP RD program, aims to create a 65 nm MAPS sensor with a small collection electrode. This innovative design eliminates the need for flip-chip bonding, reducing material budget and improving sensor performance.

Key Takeaways:

  • The TANGERINE project focuses on the design and development of a 65 nm MAPS sensor with a small collection electrode, aiming to improve sensor performance and reduce material budget.
