## Summary

The National Physical Laboratory (NPL) invites tenders for a Cryogen-Free Josephson Junction (JJ) Voltage System. This tender, titled "ITT_123111 - Cryogen Free Josephson Junction (JJ) Voltage System," falls under the industry category of laboratory, optical, and precision equipment. The procurement process currently stands at the "Tender" stage, with a deadline for submission on 11 February 2025. The contract is set to commence on 11 March 2025 and conclude on 10 March 2026. The system is required to operate without liquid helium, provide SI traceable DC voltages up to 10 V, and include software for automated calibration. This procurement will be conducted through an open procedure above the threshold, with a total value estimated at £350,000.

This tender presents significant opportunities for businesses specialising in advanced calibration systems and quantum standards. Companies with expertise in cryogen-free technologies and those capable of developing high-precision voltage systems are particularly well-suited to compete. Additionally, firms that can provide integrated software solutions for system operation and calibration will find this contract beneficial for business growth. Given the specialised nature of the requirement, larger enterprises with a strong track record in laboratory equipment and precision instruments are encouraged to participate.

## Notice

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.
