| Abstract: | The temperature distribution of different graphite tubes were measured withfiber optic and thermoeletricity. By comparison of the results, it shows that a tube-in-tubehas most homogeneous temperature distribution over others, therefore it has high sensitivityand high ability for the inhibition of interferences. |
