Simple Nitrogen Sublimation Cryostat for the Temperature Range of 77-45 K

摘要

A simple nitrogen sublimation cryostat for operating at 77-45 K was designed, built, and successfully tested. The major part of the apparatus is an SDS-6 commercial dewar vessel 6 L in capacity produced by NPO Geliymash. A temperature of 45 K was achieved after 5 h of forevacuum pumping at 5 L/s.
