✦ Synopsis

A single-stage nuclear demagnetization cryostat is reported with 33 moles of copper in a magnetic induction of 8 T developed for the investigation of low temperature thermometry. The lowest temperature measured with a Pt NMR thermometer was 130 PK, and the time dependent heat leak approached 0.3 nW after 80 days.

A compact 3He cryostat with a charcoal adsorption pump was constructed for use in thermometry. The cryostat fits into a liquid helium storage tank with a 51 mm neck. The 3He gas is held in a cylinder on top of the cryostat. The sample volume of the cryostat is 30 mm in diameter and 70 mm in height.
