Brookhaven Lab to move major piece of equipment
Brookhaven National Laboratory's brigade of scientists and researchers are accustomed to highly specialized and rigorous work. But a recent challenge has given them their biggest equation ever to solve.
BNL officials had to figure out a way to send its sister institute Fermilab near Chicago a huge piece of equipment, a muon storage ring whose heart is a 50-foot-wide circular electromagnet.
The problem was the 14-ton electromagnet in the ring can't be taken apart or bent -- or even wobble more than an eighth of an inch along the way, lest the internal superconducting wires be destroyed.
So the BNL and Fermilab scientists had to come up with a way to ship the delicate electromagnet a circuitous 3,200 miles -- with nary a quiver -- in the largest move in the lab's history. With dozens of lab staffers involved, it is costing $3 million.
"It's an effective use of taxpayer money because it was built here and is now being reused," said Fermilab scientist Chris Polly, project manager in charge of the move. Building a new storage muon ring at Fermilab would cost about 10 times more than moving the original one, project officials said.
The muon storage ring helps the labs study the properties of tiny subatomic particles. With the more advanced facilities available at Fermilab, the scientists in Chicago will make better use of the muon storage ring for research that can shed light on new realms of science, lab officials said. "There's Nobel Prize-winning physics lurking out there," Polly said.
Officials first considered moving the ring by attaching it to a Sikorsky helicopter, but the risk of vibrations was too high -- as well as the public risk of flying such a large object strapped to a helicopter over half the nation.
"You can't even pick up something like an SUV and fly it over houses," Polly said.
They settled on a combination of trucking and barging the ring. The ring will be attached to a custom truck fixture and driven -- at a maximum speed of 10 mph -- out of BNL and down William Floyd Parkway to Smith Point Marina. The drive is expected to take four to six hours.
The ring will then be loaded onto a specially prepared barge in Fire Island inlet. "It will take us a couple days to get it on the barge and secure it, making sure everything is set to sail," said Terry Emmert of Emmert International, a Portland-based company hired for the move. "Once you sail, it's gone and you're not going to see a lot of it until it gets to New Orleans."
The ring -- held with special fixtures to keep it stable -- is to make its way down the Eastern Seaboard, around Florida, into the Gulf of Mexico, and then up the Mississippi River to Illinois. Once the electromagnet is loaded off the barge, it will be trucked to Fermilab in Batavia, Ill., over two consecutive nights -- a trip that will require shutting down a couple of highways in the Chicago area.
They said they hope to start the move about June 20. The entire journey to Fermilab may take nearly two months. Polly said if hurricanes churn up during the voyage, the barge will have to dock and wait out the weather.
"There are only certain areas where you can park this size of load, so we have to time it so that it's not impacting the public," Emmert said.
Christine Biber of Upton attended a May public information meeting about the move, on behalf of her retirement community, Colonial Woods Whispering Pines, which sits across William Floyd Parkway from BNL.
"We live across the street," she said, describing the move as fascinating. "We'll be watching."
