Martin Perl, Nobel-winning physicist at the Stanford Linear Accelerator Center (SLAC), Stanford Linear Collider (SLC) experiment, Menlo Park, California. With a length of 3km, the Stanford Linear Accelerator is the largest of its kind in the world. The accelerator is used to produce streams of electrons and positrons, which collide at a combined energy of 100 GeV (Giga electron Volts). This massive energy is sufficient to produce Z-zero particles in the collision. The Z-zero is one of the mediators of the weak nuclear force, the force behind radioactive decay, and was first discovered at CERN, Geneva, in 1983. The first Z-zero at SLC was produced on 11 April 1989. Perl is credited with discovering the tau lepton particle in 1975 and received the Nobel Prize in 1995 for this discovery. He died in 2014.
