Abstract

A cryostat and Raman tube suitable for observing Raman spectra at low temperatures is described. The cryostat is designed so that the sample may be maintained at any desired temperature between 20°K and room temperature, using only liquid air or liquid hydrogen as refrigerant. Samples which are liquids, solids, or gases at room temperature can be studied. The refrigerant is confined to an all-metal system, an extremely desirable feature when liquid hydrogen is used for cooling, but, nevertheless, good thermal contact with the sample is achieved. The cryostat is used in conjunction with a Lane-Wells Raman spectrograph and power supply. The intensity of illumination is about half that obtained with the standard Lane-Wells lamp housing at ordinary temperatures.
