تم استخدام نموذج لي لتوصيف البلازما المحرقية في جهازي البلازما المحرقية UNU/ICTP PFF و امير كبير
Amirkabir plasma focus device (APF و حساب مردود الأشعة السينية اللينة منها عند العمل مع غاز النتروجين، و ذلك بالاعتماد على وسطاء بنك المكثفات و وسطاء الأنبوبة و وسطاء التشغيل المعتمدة حالياً.
وجد أن مردود الأشعة السبينية اللينة يتغير بتغير الضغط و يزداد حتى يصل إلى قيمة مثلى من أجل كل جهاز بلازما محرقية، و ذلك مع الحفاظ على وسطاء بنك المكثفات و كمون التشغيل مع التغيير المنتظم للوسطاء الأخرى.
The Lee code is applied to characterize the plasma focus in two
plasma focus devices UNU/ICTP PFF and Amirkabir plasma focus
device (APF),
and for optimizing the nitrogen soft x-ray yields based on bank,
tubes and operating parameters. It is found that the soft x-ray yield
increases with changing pressure until it reaches the maximum
value for each plasma focus device, with keeping the bank
parameters, operational voltage unchanged but systematically
changing other parameters.
