An Economical and Efficient Helium Recovery System for Vibration-Sensitive Applications

POSTER

Abstract

Here, we report the design of a liquefaction system that is ideal for recovering the helium (He) vapor from vibration-sensitive cryogenic instruments. We demonstrate its performance by recycling the boil-off from a commercial low-temperature scanning probe microscope (SPM). It features a very high He recovery rate and induces negligible vibration noise to the SPM. Given its adaptability, affordability, and homemade-friendly nature, we anticipate that our system will impact a broad spectrum of research fields.
