Scanning Electron

Ultimate resolution in the scanning electron microscope is determined not only by the diameter of the incident electron beam, but by interaction of that beam with the specimen material. Generally, while minimum beam diameter diminishes with increasing voltage, due to the reduced effect of aberration component and magnetic interference, the excited volume within the sample increases with electron energy. Thus, for any given material and imaging signal, there is an optimum volt age to achieve best resolution.In the case of organic materials, which are in general of low density and electric ally non-conducting; and may in addition be susceptible to radiation and heat damage, the selection of correct operating parameters is extremely critical and is achiev ed by interative adjustment.

Overall Performance

The electron source is the most important component of the Scanning electron microscope (SEM) since it is this which will determine the overall performance of the machine. The gun performance can be described in terms of quantities such as its brightness, its source size, its energy spread, and its stability and, depending on the chosen application, any of these factors may be the most significant one. The task of the electron gun in an SEM is, in fact, particularly difficult because of the very wide range of operational parameters that may be required e.g a variation in probe size of from a few angstroms to a few microns, and a probe current which may go from less than a pico-amp to more than a microamp. This wide range of operating parameters makes the choice of the optimum source for scanning microscopy a difficult decision.Historically, the first step up from the sealed glass tube ‘cathode ray generator’ was the simple, diode, tungsten thermionic emitter.

Abstract Technical support of producers of agrarian products has always been and will remain a topical issue in realities of agrarian sector of Ukraine. In recent years, integrated forms of agricultural enterprises have become more widespread, which make it possible to increase and renew a machine-tractor park of their participants. In course of study four main technologies of soil cultivation and their impact were considered, an amount of necessary machinery and equipment, energy and labor costs, and impact on quality indicators of soil health. Also, main organizational forms of enterprises that provide equipment rental services or perform fieldwork were analyzed. Proposals were made regarding a merger of existing enterprises into agro technical centers, which would increase an efficiency of their functioning and cover functions of regional self-government. Also, the most common forms of machinery usage by agricultural enterprises were considered.
