Cryogen-Free Cooling Apparatus

A cryogen-free cooling apparatus for cooling a sample, comprising

• a vacuum chamber,
• a first cooling device which is configured to generate a first temperature in the vacuum chamber to provide a main thermal bath,
• a second cooling device, which is in connection with a sample stage on which a sample is to be arranged, wherein the second cooling device is a solid state cooler which is configured to provide a second temperature to the sample stage, and wherein the second temperature is different from the first temperature, and
• a sample loading device which is configured to change the sample while operating the first cooling device and the second cooling device,
• wherein the sample stage is held in the vacuum chamber by a first mechanical suspension of low thermal conductivity such that the sample stage is thermally decoupled from the main thermal bath, wherein the first mechanical suspension is provided by a plurality of first fibers.
