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.

The current projection contains one award release, not a verified chain of planning, tender, award, contract and modification records. Dates are shown in source-field order and are not silently repaired.
A company profile appears only when this release carries a usable company number. Name-only suppliers remain name-only.
No supplier is named in this projection. That does not prove the notice had no supplier in every source version.
