Abstract

A spherical plasma focus device with two concentric electrodes is simulated using equal amount of deuterium and tritium mixture as a working gas. The developed model is used to investigate the effect of gas pressure and charging voltage on dynamics of current sheath in spherical plasma focus. While charging voltage is varied from 15 kV to 30 kV to see the effect of voltage, gas pressure is increased from 1 Torr to 20 Torr for gas pressure study. In this work, it is found that there is a strong correlation between current sheath dynamics and investigated parameters which are gas pressure and charging voltage.

BASINÇ VE VOLTAJIN KÜRESEL PLAZMA ODAK CİHAZI DİNAMİ ÜZERİNE ETKİSİ

Abstract

Eşit miktarda döteryum ve trityum gazlarının karışımı kullanılarak eş merkezli elektrotlara sahip küresel plazma odak cihazı modellenmiştir. Gaz basıncının ve voltajın küresel plazma odak cihazındaki plazma tabakası üzerindeki etkilerini incelemek için, geliştirilen model kullanılmıştır. Voltajın etkisini gözlemlemek için, voltaj 15 kV ile 30 kV arasında değiştirilirken, benzer şekilde gaz basıncının etkisini görebilmek için de gaz basıncı 1 Torr'dan 20 Torr'a doğru arttırıldı. Bu çalışmada araştırılan parametreler olan gaz basıncı ve voltaj ile plazma tabakasının dinamiği arasında güçlü bir bağlantı olduğu bulunmuştur.
