3D Construction View of Differential Pumping Chamber with Detector Board of Environmental Scanning Electron Microscope
 Neděla, Vilém
This paper deals with construction of the differential pumping chamber with a detector board for adaptation of the scanning electron microscope (SEM) to the environmental scanning electron microscope (ESEM). ESEM allows work at higher pressure in some parts of the microscope. It focuses especially on the 3D construction view of the differential pumping chamber together with the detector board of the differential pumping chamber and it comments reasons of necessity of the assembly of these parts into the environmental scanning electron microscope.

The system for 129Xe polarization - the operating modes
 Rychnovský, Jan
The main tendency of this paper is to bring a close view of polarization 129Xe that can be used in NMR analyses. Nuclear Magnetic Resonance - NMR, creates a base for an elementary spectroscopic analysis of unknown substances. The main experiment is still in theoretical preparations. But principle of the described system will be used in practice. We have a theoretical attainments about the research and small details are solved. Above all I write about operating modes which will occur during the polarization of 129 Xe.
