Caption: Silicon strip 'ladder' for particle detector. Gloved fingers hold a silicon strip 'ladder' which forms part of the silicon vertex detector at the core of the D-Zero subatomic particle detector at the Fermi National Accelerator Laboratory (Fermilab), near Chicago. The ladder's three lower segments consist of hundreds of microscopic strips of ultrapure silicon. Subatomic particles created in proton-antiproton collisions travel through the vertex detector, ionizing silicon atoms in the 400 strips and creating an electric charge that is recorded through the electronics at the top of each ladder. Some 400 'ladders', each worth $5000, go into the D-Zero vertex detector. Photographed at Fermilab in 1998.
