Experimental Study on a New Low-temperature System for Cryomicroscope

A new scheme,which takes nitrogen as a cold source and utilizes a micro-throttle refrigerator to cool the nitrogen,is presented for satisfying the temperature-drop demands of cryomicroscope.An elementary diagram of cryo-microscope's novel cold source system is given.To determine the parameters...

Description
Summary:A new scheme,which takes nitrogen as a cold source and utilizes a micro-throttle refrigerator to cool the nitrogen,is presented for satisfying the temperature-drop demands of cryomicroscope.An elementary diagram of cryo-microscope's novel cold source system is given.To determine the parameters of throttle tubes(internal diameter and length),the optimum throttling pressure,temperature drop,the refrigerating capacity and nitrogen consumption,three experiments was conducted.The results show that the internal d...
