October 2018 marks the 50th anniversary of the dedication of the Wilson Synchrotron Laboratory.
Initially built for $11million and promising to deliver cutting-edge research in elementary particle physics, it was the NSF’s largest project at that time. Fifty years later, the lab is going through its biggest upgrade in decades.
Chris Conolly looks at the concrete floor of Wilson Lab, eyeing up the numerous holes drilled by one of the contractors for the upgrade project. These one-inch holes pockmark the 10,000sf experimental hall of the Wilson Synchrotron Laboratory. In a way, these holes represent the numerous experiments conducted over the past 50 years.
There are a lot of holes. 652 to be exact, as the CHESS X-ray Technical Director and CHESS-U beamline project manager easily points out.
“It’s almost like being an archaeologist”, says Conolly, as he walks through the maze of newly constructed hutches in the experimental hall. He stops near the sector II hutches, “especially this spot here,” he says, presenting a repeating pattern of drilled holes arcing across the floor. The pattern spans a total of about 25 feet, and Chris, who has been with CHESS for the past 18 years, has no idea what was held down by the bolts marked in the floor.
