پایان نامه حاضر به تحلیل و بررسی مرحله شکست و تخلیه الکتریکی در دستگاه پلاسمای کانونی نوع فیلیپوف پرداخته است.در فصل اول این پایان نامه،واکنشهای شکافت و گداخت بررسی شده و سپس از توکامک به عنوان راکتور گداخت و ازدستگاه پلاسمای کانونی به عنوان نمونه ای کوچک از دستگاهی که واکنش گداخت می تواند در آن صورت پذیرد،یاد شده است.مراحل مختلف دستگاه پلاسمای کانونی به طور اجمالی مورد بررسی قرار گرفته و سپس ب...

A capillary electrophoretic method (CE) with ultraviolet absorption detection for baclofen in human plasma was developed. The separation was obtained by CE with 50 mM borate buffer at pH 9, followed by detection with an ultraviolet detector at 225 nm. The plasma samples were deproteinized with acetonitrile to remove proteins and to induce sample stacking. With stacking, the limit of detection (...

The addition of Kr dopant to a deuterium or deuterium–tritium dense plasma focus (DPF) is conventionally thought enhance radiative cooling the imploding sheath, resulting in tighter pinch and, under optimized conditions, increased neutron yield [M. Krishnan, IEEE Trans. Plasma Sci. 40, 3189 (2012)]. In this work, 2D radiation magnetohydrodynamic (MHD) simulations are conducted DPF at peak curre...

The observed scaling of neutron yield in the dense plasma focus (DPF) as fourth power current was principal driver growth DPF research its early days. Subsequent discovery failure this law also reason for abandonment by major laboratories. Attempts to understand have so far been inconclusive. This Letter looks at context recently introduced Generalized Plasma Focus problem and suggests a possib...

The measured current traces of alow energy AECS PF-1 plasma focus device are used for studying the formed plasma, and produced ion electron beams. Anadapted version Lee model (RADPFV5.15FIB&REB) is applied, taking into account fitting procedures between computed waveforms each shot. experiments on AECSPF-1 were performed with three different gases—helium, nitrogen, argon—for effect atomic n...
