What Does PPAC Stand For?

PPAC stands for Parallel Plate Avalanche Counter

The Parallel Plate Avalanche Counter (PPAC) is a sophisticated detector used in particle physics to measure charged particle trajectories and energies. It operates by utilizing an electric field between two parallel plates to generate an avalanche of ionization events from incoming particles. This enables precise tracking and identification of particles through the analysis of the resulting charge signals. PPACs are particularly valued for their fast response time and high spatial resolution, making them essential tools in various experimental setups, including nuclear and high-energy physics research.
