3993/JN/23 - Closed-Cycle Cryostat System (2 Lots)

Award outcome

Description

The University of Sheffield's department of Physics and Astronomy are looking to procure 2 types of closed-cycle cryostat systems for optical spectroscopy of semiconductor quantum dots (QDs). Lot 1 - Optical Table Cryostat for Photoluminescence Imaging: A closed-cycle cryostat system is required for optical spectroscopy of semiconductor quantum dots (QDs). The principal uses will be for micro-photoluminescence and photoluminescence imaging from self- assembled InGaAs QDs in the Department of Physics and Astronomy. Lot 2 - Standalone Optical Cryostat for Long Duration Measurements: Up to 2 closed-cycle cryostat systems are required for optical spectroscopy of semiconductor quantum dots (QDs). The principal use will be for micro-photoluminescence measurements of self- assembled InGaAs QDs in the Department of Physics and Astronomy, in particular long-duration measurements under resonant laser excitation that require very high stability and low vibration. This is an FTS open exercise. The ITT can be downloaded by registering and expressing your interest on the University`s e-tendering system https://in-tendhost.co.uk/sheffield If you have any questions or comments in relation to this tender they must be submitted via the In-tend system, this can be accessed at https://in-tendhost.co.uk/sheffield Completed tenders must be returned through the same e-tendering system. The University of Sheffield is not a contracting authority for the purposes of the Public Contracts Regulations 2015 (Directive 2014/24/EU) as amended by the Public Procurement (Amendment) (EU Exit) Regulations 2020. The University is, on a voluntary basis, operating under the Public Contracts Regulations (as defined above) for this procurement case and is therefore advertising this opportunity in Contracts Finder with an obligation to comply with these regulations.
