Esr in Pulsed Fields
Very strong magnetic fields are needed to study magnetic resonances that are broadened by impurities, lattice deformation or other interactions such as the exchange energy in antiferromagnets. Certain phenomena that can be studied by means of magnetic resonances will occur only at very high magnetic fields, such as magnetic field induced phase transitions in the crystal lattice or in the arrang...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولA New Pulse Generator with Very Fast Rise Time
instrument displays voltage changes faster than 10 9 second and has a high sensitivity of 1 millivolt. With its aid much fruitful develop ment effort has been conducted by many groups. Now, fast circuit investigations are further assisted by a versatile new pulse generator which provides pulses as short as 1 nanosecond ( 10 9 second). The pulses are provided at a high signal level of 10 volts a...
متن کاملA Tesla-pulse forming line-plasma opening switch pulsed power generator.
A pulsed power generator based on a high-voltage Tesla transformer which charges a 3.85 Ω/55 ns water-filled pulse forming line to 300 kV has been developed at Loughborough University as a training tool for pulsed power students. The generator uses all forms of insulation specific to pulsed power technology, liquid (oil and water), gas (SF(6)), and magnetic insulation in vacuum, and a number of...
متن کاملSpectral Rotation in Pulsed ESR Spectroscopy*
The technique of pulsed Fourier transform NMR spectroscopy is well developed and understood. The equivalent technique for ESR has been slower to be developed, but recent developments in ESR instrumentation have now made FT ESR possible. In this paper we consider the requirements for rotating the magnetization associated with an ESR spectrum by a microwave pulse. In addition, techniques for reco...
