Supply and Installation of a 1.8 to 300 K Cryostat to the University of Birmingham

Tender description

A contract notice was published for this in Contract Finder on 6th January 2021 however the system cannot link this notice to the award. .SUMMARY OF THE REQUIREMENTS (MAIN DELIVERABLES) The University of Birmingham invited tenders for supply of a variable temperature cryostat system, for carrying out experiments in condensed matter physics. The cryostat should be able to maintain any temperature between 1.8 and 300 K. Extra points will be awarded for guaranteed temperatures below 1.8 K. The cryostat system should contain a superconducting magnet that can apply fields of up to 12 T, of either polarity. There should be a radiation shield between the sample space and the magnet, so that the magnet remains superconducting and able to apply a field of 12 T even when the sample space is held at a temperature of 300 K; this radiation shield is in general the defining feature of a variable temperature system. The tenderer should supply a power supply for this magnet. The system is to be a dry system, that is, it should operate without replenishment of any cryogenic liquids. The tenderer is expected to offer all of the pumps, compressors, reservoirs, and filters necessary for operation of such a system. The tenderer should pay particular attention to the sample space requirements, which are larger than for typical transport measurements. The system should include three measurement inserts: a standard insert, a sample-invacuum insert, and a helium-3 insert. The helium-3 insert is intended to allow temperatures down to 0.3 K.
