The next generation of current measurement for ionization chambers
Low-loss sealed-gas-dielectric standards are readily available for this range: such capacitors can have phase angles less than 10 −5, resulting in a very small residual non-linearity to the voltage ramp, and have low relative sensitivity to temperature – a few 10 −6 / °C is typical. If a sealed-gas-dielectric capacitor is used, there is ...
