Abstract

Bu çalışmada, gelistirilen MHD modeli kullanılarak, uygulanan voltajın nötron ve iyon üretimi, radyasyon yayılımı ve iyon özellikleri üzerindeki etkileri, voltaj değerleri 15 kV ile 30 kV arasında 1'er kV değerler değiştirilerek incelendi. Joule ısınımı, elektron yakalama, bremsstrahlung radyasyonu ve çizgi radyasyonu radyasyon terimleri olarak hesaplanırken ışın-iyon hızı, enerjisi ve yoğunluğuda iyon özellikleri olarak bu çalışmada hesaplandı. Diyot voltajı altında hızlanan yüksek enerjili iyonların neden olduğu Işın-hedef nötron üretim mekanizması baskın nötron üretim mekanizmasıdır. Nötron üretiminin yanısıra diyot voltajıda hesaplanmıştır.
Bu çalışmada, 30 kV voltaj için maksimum nötron üretimi 2.63 x 10^13 iken, ışın-iyon enerjisi ve hızı sırasıyla 61 keV ve 240 240 cm/µs 'ye ulaşmıştır.

Neutron and Ion Production with Various Applied Voltages in Spherical Plasma Focus

Year 2020, Volume: 11 Issue: 1, 135 - 141, 27.03.2020

Abstract

In this work, the applied voltage effect on neutron yield and ion production are studied by varying the charging voltage between 15 kV and 30 kV with 1 kV increment to investigate neutron yield, radiation emissions and ion properties using the developed MHD model. While Joule heating, radiative recombination, bremsstrahlung and line radiation are calculated as radiation terms, beam-ion speed, energy and density are calculated as ion properties. The dominant neutron production mechanism is beam-target which results from the accelerated energetic ions under the diode voltage which is calculated along with neutron yield. In this study, while maximum neutron yield is 2.63 10^13 for 30 kV charging voltage, beam-ion energy and speed reach 61 keV and 240 cm/µs, respectively.
