【摘要】 本文描述了工作在三厘米波段的,利用半开放式梳形慢波结构作为吸收室的行波式波谱仪,同时还描述了高频调场、高频调频和高频调幅行波式波谱仪的工作原理,线路结构,以及它们的某些性能的比较。最后还从理论上考虑了行波式波谱仪的灵敏度。实验结果表明,行波式波谱仪其有结构简单,操作容易,工作稳定等优点。提高慢波结构的慢波系数和利用高频调制,可以提高波谱仪的灵敏度。计算结果表明,行波式波谱仪的灵敏度是可以同腔式波谱仪的灵敏度相比较的。更多还原

【Abstract】 The Comb type slow wave structure of Open boundary has been usedinstead of the ordinary absorption cell in this X band traveling-waveEPR spectwmeter. The principles and block diagrams of the traveling-wave EPR spectromter with high frequency field modulation, high fre-quency FM and high frequnecy AM have been deseribed, and the charac-teristics of spectrometer with different schemes of modulation have beencompared. The sensitivity of the traveling-wave EPR spectrometer hasbeen determined theoretically at the end of this paper. It has been shown experimentally that, the traveling-wave EPR spectro-meter had its own advantage of simple construction. easy operation andhigher working stability. The sensitivity of spectrometer could be stillmuch incresed by means of the rasing of frequency of modulation andthe value of slow wave coefficent of the structure, It was shown thoretic-ally that the sensitivity of traveling-wave EPR spectrometer could be com-pared with the spectrometer of cavity type with the same scheme ofmodulation.更多还原
