## Summary

UK Research & Innovation (UKRI) has initiated the tender process for the procurement of a Cryogen-Free Bottom-Loading Dilution Refrigerator System. This equipment is crucial for a research programme funded by a UKRI Future Leaders Fellowship at the Particle Physics Department (PPD). Categorised under laboratory, optical, and precision equipments (excluding glasses), and involving a contract value of GBP 204,000, the contract is set to start on 9th May 2025 and conclude on 8th May 2026. Based in the South East of the United Kingdom, the tender is currently in the planning stage with an end date for submissions on 31st March 2025.

This tender offers significant opportunities for businesses, particularly small and medium-sized enterprises (SMEs), to contribute specialised equipment for cutting-edge research in ultra-low temperature photosensor research and dark matter experiments. Companies that specialise in laboratory and precision instruments would be well-suited for this tender, which promises long-term engagement in a high-profile scientific research context. The open procedure procurement method ensures a fair competition, providing a platform for businesses to expand their portfolio and gain recognition in a prestigious, innovative research initiative.

## Notice

This procurement forms the basis for part of a research programme being undertaken at PPD and funded through a UKRI Future Leaders Fellowship, a prestigious funding opportunity designed to support exceptional researchers and innovators in the UK. Dedicated funds were awarded as part of this grant specifically for this procurement, since there is currently no such system within PPD for this research to take place. The system delivered through this procurement will be used for dedicated photosensor R&D at ultra-low temperatures (~20 mK) for the QUEST-DMC dark matter experiment, one of many experiments that STFC PPD is involved in. The system will be housed inside a larger, cryogenic laboratory ("cryolab") currently being established within PPD. The cryolab will provide a dedicated cryogenic facility within PPD for liquid noble R&D in the context of low background rare-event searches, and is applicable to several different experiments that PPD is presently involved with. The cryolab is in the process of being refurbished to specifically satisfy the requirements for this system, therefore there should be no service conditions or environmental factors that should impact the operation or performance of this system.
