Meciianism of Secondary Emission and Single Particle Statistics from Low Density Films of Alkali Halides*
I AI3STI1ACT The mechanism of field enhnncctl secondary emission has been studied es-pcrimcntally in detail for KC1 low density transmission dynodes transferred in a dry nitrogen atmosphere. By means of a Kelvin probe located at the center of a collector, dynode surface potentials and their relationship with collector potential , secondary yield, primary energy and current density have been stu...
متن کاملDetailed Study of the Electron-phonon Interaction in Alkali Halides” Part Ii Transmission Secondary Emission from Alkali Halides
The phenomenon of secondary emission from alkali halides is studied in transmission. This allows the variation of one more parameter (thickness) than in conventional reflection studies. An empirical method based on published results of scattering by thin foils is used to determine the spatial dependence of the internal electron excitation function. The results of the Monte Carlo calculations pr...
متن کاملStatistics of Transmission Secondary Emission
The statistical distribution of the number of emitted secondary electrons per primary incident on transmission alkali-halide dynodes has been studied. For high primary energies (1 MeV), a model based on the theory of dielectric energy loss and the secondary electron-phonon interaction is proposed to account for statistical distributions. Measurements of distributions from 500 i-thick films of C...

15 صفحه اولthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
