(PhysOrg.com) -- The temperature is now stabilized at a mild 68 °F (20 °C), support pedestals are in place and aligned, the paint is dry and physicists are moving in. That's the scene in the Linac Coherent Light Source Undulator Hall, where the last items on the civil construction punch list are being checked off. Last week, after extensive monitoring and testing of the air handling system, workers began moving in crates containing the heavy, precision-aligned steel girders that will support the LCLS undulators.
