UKI LONDON (UK UNITED KINGDOM)
Description:
A complete primary voltage calibration system is needed that operates without liquid helium, providing SI traceable DC voltages up to 10 V and AC voltages up to a few kHz, along with automated calibration software.
The National Physical Laboratory (NPL) requirement is for a complete primary voltage calibration system built around a Josephson array quantum standard.
The purpose is to move away from the current generation of standards that use liquid helium to cool the sample to one that is liquid cryogen-free with the aim that no liquid helium should be required for either cool-down or routine operation, and hence the system should be capable of continuous operation for periods of at least several months.
The system should be capable of providing: SI traceable DC voltages up to 10 V, with an uncertainty better than 1 nV/V. software to run the system and automate the calibration of standards. the capability to generate AC voltages up to a few kHz.
