Abstract
A special bubble-free cryostat for precise optical measurements of sam ples compressed in a high-pressure cell has been built and put into op eration. Liquid nitrogen around the high-pressure cell is prevented fr om boiling thanks to a slight overpressure in the closed cryovessel; i nstead, cryoliquid is boiling at atmospheric pressure inside an evapor ator.
