The Linac Coherent Light Source (LCLS) is the world’s first hard X-ray free-electron laser and generates ultra-fast, ultra-bright pulses of X-ray laser light designed to provide new insights into the atomic world. LCLS-II is the second X-ray laser facility at SLAC. A new injector was installed in the Sector 10 tunnel and the drive laser at Sector 10 was housed in a new Injector Support Building that Gordon Prill built on the surface directly above the injector tunnel. LCLS-II will give investigators access to new regions of the X-ray spectrum and improved control over the X-ray beam.

Gordon Prill provided construction services to replace the existing Sector 10 Building with a new structural steel frame with the necessary equipment to support the requirements for LCLS II. Tasks included: demolish existing building and site paving and furnish and install: concrete floor slab, foundations, exterior walkways, mechanical pads, structural steel frame for building and mechanical equipment canopies, metal cladding for walls and roofs, fabrications including bollards, insulation for walls and roofs, partitions, doors, and glazing, floor, finishes. fire protection systems including standpipe and sprinklers systems and fire extinguishers and instrumentation and controls. Size: 50,000 sq. ft. Construction value: $7 million.
