摘要：

A novel apparatus, based on cryocooler, for rapid thermal conductivity measurements between 8 K and 300 K is presented. It consists of a removable sample test bar on which bulk samples can easily be mounted and then placed in the described measurement device. This fast mounting measurement system uses a standard steady-state absolute thermal conductivity measurement and allows for excellent thermal stability and mechanical vibration isolation from the cryocooler. The distinction of this system is rapid mounting and measurement of thermal conductivity with high accuracy and precision in data acquisition. In addition, this system allows for versatility in its use, such as the specific heat and the linear thermal expansion measurement. The design of this apparatus, measurement specification, and thermal conductivity of standard materials measured in this system are presented.
