Procurement of a Cryogen Free Measurement System

University of Bristol has awarded a Cryogen Free Measurement System

The equipment will form part of the wider Quantum and Soft Matter (QSM) research theme's capabilities in the School of Physics, Faculty of Science and Engineering, at the University of Bristol. The QSM theme is recognised as one of the UK's leading centres in the study of quantum materials - notably exotic / high temperature superconducting and magnetic materials. Research in the QSM theme has attracted significant research income over the last decades, including a helium liquefier, a range of 'wet' cryogenic systems, as well as hosting a Centre for Doctoral Training in Condensed Matter Physics. Given the recent challenges around the price and availability of helium globally, this turn-key closed-cycle system will provide a key additional level of flexibility and fast-turnaround for sample screening and basic characterisation, before utilising lower temperature and/or higher magnetic field measurements either in Bristol or at a range of facilities worldwide.

The equipment is comprised of two main components: (1) a state-of-the-art closed cycle cryostat with base temperature better than 1.8 K; (2) a superconducting magnet capable of applying fields in excess of 7 Tesla with high uniformity to a sample stage mounted inside the cryostat.
