Dry dilution refrigerator with anti-vibration system for mK scanning probe microscopy

Описание

NPL is seeking a solution for a new dry dilution refrigerator (“the system”) in which scanning probe microscopy experiments will be carried out at mK temperatures on live superconducting quantum circuits. NPL wishes to use the system for atomic scale scanning tunnelling microscopy and atomic force microscopy. As such, the system must provide a low vibration and high coherence environment (light tight mixing chamber volume). Significant emphasis will be placed on the lowest possible vibration levels that can be achieved. It is anticipated that a solution provides both a mK vibration isolation…
