A novel ionization gauge was developed where the electron beam is guided through the ionization space in a straight path. This design was chosen in order to develop a more stable ionization vacuum gauge suitable as reference standard in the range of

Input and output stages of the second generation of ultrastable low-noise current amplifiers can be conveniently calibrated by means of a cryogenic current comparator. The uncertainty achievable for measurement durations of less than 2 h makes our ca

The noise and stability of a current source are limited by the quality of components used for construction, such as the voltage reference chips, resistors, and power supplies. A state-of-the-art commercial current source typically exhibits a stabilit

An ultrastable low-noise current amplifier (ULCA) has been transferred between two laboratories, NPL and PTB, four times, with three of the transfers yielding a relative change in the trans-resistance gain of less than $2 \times 10^{-7}$. This is a n

The ultrastable low-noise current amplifier (ULCA) was developed as an advanced instrument for the improved measurement of currents generated by single-electron transport (SET) devices. It was optimized for direct currents in the picoampere range, an

This paper describes the implementation of a digital robust controller in a cryogenic current comparator. The controller was designed applying $ {\cal {H}_\infty }$ control theory and it was programmed in a home-made digital unit. Experimental compar
