Tank IV is the last section of the ISIS normal conducting drift tube linear accelerator. It operates whilst under vacuum. All components will be cleaned and conform to ISIS vacuum specification. The 12m long tank will consist of six 2m long by 1m diameter vessels bolted together. The new tank will be a direct replacement, as the frequency is dictated by the ISIS machine. For ease of maintenance and safe radiation working levels side hatches will be added to aid drift tube replacement, should the need arise in the future. The main requirements are: - The Tank needs to be a direct dimensional copy of the existing tank for the physics to operate correctly. - The Tank needs to hold a vacuum at pressures of 1x10-7 mbar, with an acceptable leak rate of 1x10-8 mbarl/s. - A method of aligning the tanks is important, so a rail alignment system will be used. - The tank will need to be cooled to 1 deg delta T and will operate at max gauge pressure of 3.85 Bar. - The tank will need surface treatment after manufacture using high conductivity oxygen free copper plating. - Delivery is required within 12 months of Contract placement. ## CPV classification Linear accelerators Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/4a42807f-bc06-4302-8d3d-3967d173aa05) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
