Pulsed Electron-Beam Heating
A pulsed, 20 kv electron beam is focussed upon a vapor-deposited thermocouple, and the resulting temperature vs. time response is studied. The experimental data show much scatter, but are consistent with the theoretical prediction that the characteristic thermal response time T is proportional to d , where d is the beam diameter at the thermocouple. From these data, for the soft-glass substrate...
متن کاملElectron Beam Generated Solitary Structures in a Nonuniform Plasma System
Recent observations by the FAST satellite have identified numerous occurrences in the downward auroral current region of fast solitary structures with a characteristic size of a few local Debye lengths. We utilize a 2.5D electrostatic particle-in-cell code to investigate the generation of such structures by the interaction of narrow energetic electron beams with a gravitationally-bound exponent...
متن کاملThree-dimensional model of electron beam generated plasma
A three-dimensional model for magnetized electron beam generated plasma is described, which includes a coupled fluid simulation of the bulk plasma and a Monte Carlo model for beam electrons. A modified form of the classical expressions for magnetized-plasma electron transport coefficients is used in the fluid plasma model. The plasma model is calibrated and validated using Langmuir probe measur...
متن کاملon the teacher-generated v.s. leaner-generated noticing-the-gap activities in language classes
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
On the Corotational Beam Element Formulation in Large Deformation Analysis
This paper sheds more light on the co-rotational element formulation for beams with uniform cross-section. The co-rotational elements are commonly used in problems in which a structure undergoes a large deformation. In this study, the foregoing element obeys the Euler-Bernoulli beam assumptions. Unlike the formulations presented in the literature, in this paper, a number of local nodal coordina...
