Popis: | A fully automated adiabatic calorimeter for a temperature range from 20 K to 670 K has been constructed. The system is used for specific heat measurements on solid state phase transitions with an absolute accuracy of 0.4 %. Usual temperature increments are 0.2 K or less per measuring cycle. The sample temperature is determined bv thermistors or diodes with a resolution of 0.1 mK. The whole measuring process is computer controlled: all received data are storedon data tape so that they can be easily evaluated. The performance of the apparatus is illustrated by results obtained on a sapphire sample. |
