TL;DR: The BaBar detector at SLAC B-factory is based on a hexagonal cell design with 7104 cells arranged in 40 layers and drift gas helium:isobutane (80:20%). Performance optimization and integration requirements led to an electronics design that mounted the amplifier-discriminator and digitizing circuitry directly on the endplate as discussed by the authors.
