## Description

The National Physical Laboratory \(NPL\) requirement is for a refrigerator to house one of our Cryogenic Current Comparators \(CCC\)\. Currently the system is mounted in a dewar of helium to provide the necessary temperature, but this requires refilling periodically and we wish to move to a closed setup which does not need additional cryogens for sustained periods of operation\. The asset must therefore: 1\) Allow the existing CCC components to be mounting in the cold space of the fridge\. 2\) Hold a steady temperature of 4 K or less for a sustained period\. 3\) Not require any additional liquid cryogens for cool-down or whilst running\. Note: Due to the Prior Indicative Notice \(PIN\) Reference 2024/S 000-019150 Published on 21/06/2024 the Authority is reducing the tendering timescales to 21 days\.
