Résumé

The authors investigated cooling performance of pulse tube refrigerators in a temperature range from about 270 to 80 K from the viewpoint of expanding the application temperature range from cryogenic to low temperature. An orifice pulse tube refrigerator, that was designed and optimized for helium, was tested. Nitrogen, and also helium, was used as working gas. It was found that the performance of the refrigerator with nitrogen was more influenced by an orifice valve with a connecting tube between a hot end of a pulse tube to a reservoir than that with helium, and that the pulse-tube refrigerator designed and optimized for helium did not always work as refrigerators with high performance for nitrogen.
