Rotor electrometer: New instrument for bulk matter quark search experiments Journal Article uri icon



  • The rotor electrometer is a new instrument which we hope will make possible searches for rare fractionally charged impurities in very large quantities of matter. The ultimate goal of the project is to be able to measure the net charge of 10 mg samples of any material to an accuracy of 0.05 qe in a few minutes (qe is the electron’s charge). This paper reports the achievement of subelectron (0.3 qe) charge resolution with the new device. We discuss effects which limit the resolution and consider prospects for improving the performance to the point where a fractional charge search may be attempted.
