Abstract
A new proportional counter for CEMS, in which the sample temperature can be raised up to 740 K, is described. Unlike the reported design by Isozumi et al. [1], where the entire chamber was heated from outside, only the sample and sample holder as well as the flow-gas were heated in the present design. Counting characteristics of several flow-gases were compared at room temperature and at 507 K, and 90%He/10%CH 4 gas was found to give the most stable counting. Promising applications of the counter are demonstrated by presenting the CEM spectrum of the stainless steel surface at 738 K, the comparison of Mössbauer parameters of α-iron for TMS and CEMS up to 600 K and the determination of nitrogen content together with the chemical states of iron in the ion nitrided steel surface.
