Assembling the anti-transformer in the power room of the Alcator C tokamak. From left to right: Technician/machinist Ed Thibeault, Head of Operations Dave Overski, and technical staff supervisor Frank Silva. The anti-transformer is an external decoupling circuit used to cancel the mutual inductance between the equilibrium (poloidal field) coils and the Ohmic transformer (center stack).
Photo taken by U.S. Department of Energy photographer Peter Schweitzer circa 1982–1983, while he was on site to document Alcator C operations.
