The Rotor Electrometer: A New Instrument For Fractional Charge Searches
- Stanford Univ., Stanford, CA (United States)
A very sensitive electrometer with a charge resolution of less than the charge of one electron is described. The instrument has been developed in hopes that it will allow fractional charge search experiments with very large samples. The method employed is electronic, in contrast to other fractional charge search techniques which involve the measurement of a small force. Pairs of conducting pads are placed around the perimeter of a high speed magnetically levitated rotor, with one member of each pair grounded, and the other capacitively coupled to a low noise JFET amplifier.
