## Summary

UK Industrial Fusion Solutions Ltd., based in Culham Campus, Abingdon, is spearheading the procurement process for the "STEP MAST-U EBW II Upgrade" project. This open competitive procedure under the industry's goods category is oriented towards sourcing suppliers to deliver microwave tubes and equipment, specifically Two Gyrotrons for the MAST-U upgrade in Oxfordshire. Prospective suppliers should note key dates: an enquiry period closing on 17th March 2026, tender submission ending on 25th March 2026, and an award period concluding by 3rd April 2026. The contract is intended to commence on 20th April 2026 and will run until 29th September 2028, with a gross contract value of £7.8 million.

This project presents significant business growth opportunities, particularly for SMEs specialising in microwave technology or similar engineering disciplines. Companies experienced in delivering complex goods within the scientific research sector may find this tender particularly well-suited, given the project's aim to validate microwave technologies with Electron Bernstein Waves. The procedural framework – incorporating a Pre-Qualification Questionnaire (PSQ) stage followed by an Invitation to Tender (ITT) – allows for a thorough competitive evaluation while offering suppliers a transparent and structured engagement pathway.
