ELECTROMETER Definition
An electrometer is an electrical instrument for measuring electric charge or electrical potential difference. There are many different types, ranging from historical hand-made mechanical instruments to high-precision electronic devices. Modern electrometers based on vacuum tube or solid state technology can be used to make voltage and charge measurements with very low leakage currents, down to ...
متن کاملModeling and thermal parametric analysis of U-pipe evacuated tube solar collector for four different climates in Iran
In this study, thermal performance of the collector with analytic and quasi-dynamic method is evaluated based on energy balance equations for each part of the U-pipe evacuated tube solar collector. Using this approach, effect of different parameters such as tube size, overall heat loss coefficient, absorber tube absorptivity, mass flow rate and air layer thermal resistance on thermal performanc...
متن کاملAn integrated-circuit based wide range electrometer implemented with automatically ranged linear display
In the measurement of dc current for the range of 10-6-10-‘2 A, a stable electrometer is required. The electrometer circuit is usually implemented by simply probing the voltage drop on a load resistor using a sensitive voltage amplifier.’ In this scheme, different values of the load resistor are needed to cover multi decade range without saturating the voltage amplifier. This results in differe...
متن کاملNarrow-band microwave radiation from a biased single-Cooper-pair transistor.
We show that a single-Cooper-pair transistor (SCPT) electrometer emits narrow-band microwave radiation when biased in its subgap region. Photoexcitation of quasiparticle tunneling in a nearby SCPT is used to spectroscopically detect this radiation in a configuration that closely mimics a qubit-electrometer integrated circuit. We identify emission lines due to Josephson radiation and radiative t...
متن کاملHigh-resolution Electrometer with Micromechanical Variable Capacitor
We have designed, fabricated, and operated an electrometer with a noise-equivalent resolution of 535 electrons rms (86 aC). The electrometer incorporates a silicon resonator that acts as a variable capacitor and is fabricated using a new self-assembly process that demonstrates for the first time the integration of lownoise, low-leakage JFETs with SOI structures. The resolution of the measuremen...
