Abstract

Sülfür heksaflorür (SF6), küresel ısınma potansiyeli olmasına rağmen yalıtkanlık özellikleri nedeniyle endüstride sık kullanılan bir gazdır. SF6'nın elektron etkisi ile iyonlaşma çalışmaları, özellikle çarpışma sonucu açığa çıkan parçacıkların enerji ve açısal dağılımlarının ölçülmesi, iyonlaşma sürecinin temel fiziksel özellikleri ve SF6 molekülünün yapısı hakkında değerli bilgiler sağlamaktadır. Bu çalışmada, SF6'nın elektron etkisi ile iyonlaşma olayı için ikili diferansiyel tesir kesiti (DDCS) ölçümleri yapılmıştır. SF6 molekülü 50-350 eV enerjili elektronlar ile çarpıştırılarak ortaya çıkan elektronlar enerji ve saçılma açısının fonksiyonu olarak dedekte edilmiştir. Bu çalışmanın bulguları, SF6'ın moleküler yapısı hakkında önemli bilgiler sunmakta olup, molekülün yüklü parçacıklar ile olan etkileşimlerinin anlaşılmasına katkı sağlayacaktır.

Measurement of Double Differential Cross Sections for Electron Impact Ionization of Sulfur Hexafluoride Molecule

Abstract

Sulfur hexafluoride (SF6) is a widely used insulator in the industry, but it also has a high global warming potential. Studying electron impact ionization of SF6, particularly measuring the energy and angular distributions of the collision products, can provide valuable information about the underlying physics of the collision process and the nature of SF6 molecule. In this study, double differential cross sections (DDCSs) for electron impact ionization of SF6 have measured using a crossed beam experimental setup. The incident electron beam, with an energy range of 50-350 eV, was directed towards a target gas composed of SF6, and scattered electrons were detected as a function of the energy and scattering angle. The findings of this study offer significant insights into the molecular structure of SF6 and will contribute to enhancing the understanding of charged particle interactions involving SF6.
