QMATCH: Quantum Measurement of Atomic Charge
ORAL
Abstract
The electric charge neutrality of atoms and bulk matter is an experimental fact established through classical measurements at the 10-21e/nucleon level. I will present the design of a new experiment, QMATCH: Quantum Measurement of Atomic Charge, which will use atom interferometry to test the charge neutrality of atoms at an unprecedented level using the scalar Aharonov-Bohm effect. The estimated sensitivity per shot is expected to exceed current bounds by more that a factor of ten. I will discuss sources of systematic error and the differential measurement strategies we will use to control them. I will also describe the design and construction of the high voltage in-vacuum electrodes needed for the experiment.
