Tenders Are Invited For Laboratory, Optical And Precision Equipments (Excl. Glasses) – Two Cryogen-Free Dilu ... in Switzerland

Work Detail

Laboratory, Optical And Precision Equipments (Excl. Glasses) – Two Cryogen-Free Dilution Refrigerators. Epfl Wishes To Acquire Two Cryogen-Free Dilution Refrigerators For Advanced Research At Low Temperatures. Both Systems Must Allow Operation In The Millikelvin Regime And Be Equipped With Superconducting Magnets. The First System Must Be A Large Capacity Cryogen-Free Dilution Refrigerator, Equipped With A Superconducting Vector Magnet Providing Nominal Fields Of At Least 6 T Along The Main Axis And 1 T Along Each Of The Two Transverse Axes. This System Must Also Include A Bottom Loading System, Or An Equivalent System For Rapid Sample Exchange, Allowing The Replacement Of Samples Without Heating The Entire Cryostat And Allowing The Cooling Of The Loaded Sample Holder Insert To A Temperature Below 20 Mk In Less Than 8 H. The Second System Should Be A Smaller, Cryogen-Free Dilution Refrigerator, Equipped With A Single-Axis Superconducting Solenoid Magnet Providing A Nominal Field Of At Least 8 T. This System Should Allow Rapid Experimental Turnover, With A Cooling Time From Room Temperature To Base Temperature Of Approximately 12 H Or Less Without The Magnet Installed. The Supplier Must Specify The Cooling Time With The Magnet Installed. The Equipment Will Support Cutting-Edge Research In Quantum Magnetic Materials, Superconducting Quantum Circuits, Semiconductor Quantum Devices, And Hybrid Microwave/Semiconductor Quantum Technologies. Taking Into Account The Needs Of Epfl And The Specific Scientific Objectives Of The Lqm, Hqc And Lqp Laboratories, Particular Attention Will Be Paid To The Following Areas Of Research: • Materials With Correlated Electrons, Ranging From Local Spin Clusters To New Superconductors • Semiconductor Quantum Systems At Millikelvin Temperatures And Under High Magnetic Fields • Superconducting Quantum Circuits At Microwave Frequencies • Hybrid Semiconductor–Superconductor Quantum Devices • Quantum Materials And Devices Based On Iii–V And Group Iv Semiconductor Heterostructures, Superconducting Metals And Josephson Junctions
