Critical Decision-3A Clears Way Toward Standard Model Test

Thursday, June 1, 2023 - 16:03 in Physics & Chemistry

The U.S. Department of Energy has given the greenlight for the MOLLER experiment to begin procurement of key components with its granting of Critical Decision-3A (CD-3A): Approve Long Lead Procurements. The determination allows the MOLLER project at Jefferson Lab to begin spending $9.14 million for long-lead procurements of critical items for which designs are complete. The MOLLER collaboration formed in 2006, and more than 100 physicists from more than 30 institutions are now involved. MOLLER will make a measurement of the electron's weak charge that is five times more precise than any before. The electron's weak charge is essentially how much influence the weak force exerts on the electron.
