Bill Foster: Businessman, Scientist, Independent Solutions

Bill's Science Career

Over the 25 years before being elected to represent the people of Illinois in the U.S. Congress in 2008, Bill played a leading role in several groundbreaking experiments in elementary particle physics. He also managed several multimillion dollar accelerator construction and research projects, and led teams of engineers and physicists to help build the latest round of Fermilab's giant particle accelerators. Along the way he designed and built equipment using a number of advanced technologies, including high speed electronics, superconducting magnets, analog and digital integrated circuit design, and high power electronics. Bill received several awards for these technical developments.

The IMB Proton Decay Detector

In 1979, Bill joined the IMB (Irvine-Michigan-Brookhaven) collaboration as one of the key members who designed, built and conducted research. The IMB detector was a 60-foot cube of ultra-pure water constructed in a salt mine underneath Lake Erie. The water was surrounded by 2000 light-sensitive phototubes, designed to detect proton decay. The experiment became famous for the observation of the neutrino burst emitted by a nearby Supernova (exploding star).

CDF - The Collider Detector at the Fermilab Tevatron

In 1984, Bill moved to Illinois to work at Fermilab and join one of the largest and most exciting experiments in the world. The Collider Detector at Fermilab (CDF) is the first and largest detector at the Fermilab Tevatron, the world's highest energy particle accelerator. The goal of the experiment was to discover the identity and properties of the particles that make up the universe and to understand the forces and interactions between those particles. Bill designed and built significant parts of the original equipment, and Bill and his equipment participated in the discovery of the Top Quark, the heaviest known form of matter.

Bill's Integrated Circuit Designs

In the early 1990's Bill led the team that designed a new type of integrated circuit (computer chip) that allowed particle physics collisions to be measured with unprecedented speed and accuracy. Bill's design is still being used at high energy physics experiments being built today.

The silicon "chip" is about 2mm (3/32nd of an inch) in size and contains many thousands of transistors. A typical particle physics experiment will use thousands of these specialized chips.


Bill and Fermilab's Particle Accelerators

In 1994 Bill began working on Fermilab's giant particle accelerators. During this time he managed several multi-million dollar accelerator construction and research projects. Bill was the co-inventor of Fermilab's Recycler Ring, the newest of Fermilab's giant machines. Each time Femilab's machines operate, the particle beams go through over 500 magnets that Bill designed and led the teams that built them.
