Grant for Upgrades

Thursday, October 4th, 2018

PSL, and three other universities, was awarded a $1.6 million grant from the National Science Foundation to improve the winding process for the Deep Underground Neutrino Experiment (DUNE) Anode Plane Assembly (APA). PSL has built four APAs for the ProtoDUNE detector at CERN in Switzerland, two other APAs were built by Daresbury Laboratory in the U.K.

The winder winds 24 kilometers (or 15 miles) of thin copper beryllium wire around a frame that is 6 meters (20 ft.) by 2 meters (6 feet). There are four layers of wire: the bottom and top layers are wound from one end of the frame to the other, the middle two layers are wound in a diagonal pattern. Winding is very difficult and time consuming, and with 300 APAs to be built for DUNE, it is vital to find efficiencies. This grant enables PSL, and its partner APA “factories” at the University of Chicago, Yale University, and Syracuse University, to further optimize the APA construction and winding process.
