Paper presents the results of experiments on multicapillary carbon-epoxy as a candidate material for a cathode of a pulsed electron accelerator.
Introduction Widespread use of electron accelerators as sources of ionizing radiation in various fields of science and engineering [1, 2] stimulates different developments the research of which is aimed at improving the performance of the accelerator as a whole as well as its individual parts.
An important problem for pulsed electron accelerators is a choice of material for an emitter for an electron diode [7, 8].
When testing of a new type or material of a cathode one should consider life time of the cathode as wells as its emission ability.

Porosity is an important parameter for the characterization of materials' microstructures.
This parameter describes the rate of dispersion of the nanoparticle materials within the fluid which naturally would retard the velocity if more got dispersed within the fluid.
Physically, chemical reaction parameters play a significant role in fields such as chemical engineering, organic chemistry, and materials science, where reactions are fundamental to the production of various materials, pharmaceuticals, fuels, and many other products.

Recent days, nano ZnS samples which have different morphologies used in biomarkers materials has aroused great interests.
Combining water soluble ZnS and preparation water soluble quantum dots to biological detection that have became an important problem of biomarkers materials research[5] .
In 2005 JIANG et al.[9] presents the emulsion method with ZnCl2 and TAA as raw materials, and span-80, tween-80 as compound surface active agents and utilizes the a forementioned method to produce nanometer ZnS particles.
The starting materials were Zn(Ac)2 , TAA and ethyl alcohol,all the reagents used were analytical grade without further purification.

So, the deformation of materials will vary according to the force direction as well.
The materials were selected to represent the contact of hard material (WC) and soft material (SUS304).
The properties of the materials are shown here in Table 1.
This is because the materials in contact in the process line are the SUS410 (screw material) and tool steel (screw driver material).
