two.2.4) Description of the procurement
To design and manufacture a cryostat with closed cycle cryogenic cooling system, with a 20K test piece temperature in a vacuum. With an option to include an integrated superconducting 4 Tesla magnet, in addition to its associated removable mountings and cryogenic current leads.
The cryostat within its design will include, though not limited to the following:
• Cryocooler(s) with option to retro fit (if required) for an integrated superconducting magnet.
• Cryogenic coolant supply and recovery (closed cycle) to support cryocooler(s).
• Reservoir for the circulating Helium gas (if required).
• Cryogenic chiller compatible with the cryocoolers and be of sufficient capacity to support:
• A dedicated magnet cryocooler
• Cryocoolers such as: Sumitomo RDK-500B, 40/45W @ 20K or Cryomech AL630 100w @20K
• Temperature controller for the UUT / test sample range to be agreed.
• Vacuum chamber and associated depression gauge for the UUT test environment.
• Mechanical support of UUT.
• The UUT shall have a test temperature of 20k whilst being supplied a continuous current of 1kA at up to 5v dc.
• Ambient condition current leads to supply 1kA at up to 5v dc from dedicated power supply.
• Cryogenic current leads suppling current from ambient conditions (room temperature) to the UUT of 1kA at up to 5v dc.
• Mechanical support for power leads that interface face with UUT cryogenic leads.
If selected as an initial option, the 4T superconducting magnet is anticipated to be of ‘solenoid configuration’ with dedicated cryogenic current leads to minimise heat load on the cryogenic
• The magnet may require its own dedicated cryocooler.
Both the magnet and its current leads are to be demountable such that, if required the magnet can be replaced or upgraded.
